A roundabout microstrip fixes receiving wire is planned in this paper. The recommended receiving wire for remote neighborhood [WLAN] utilizes a 2.4GHz resounding recurrence. There are numerous different sorts of receiving wires, however, we'll zero in on roundabout radio wires, which are worked to support the resounding recurrence referenced previously. As a result of this recurrence determination, the radio wire is ideal for utilization in a remote Local Area Network [WLAN]. The High-Frequency Structure Simulator programming HFSS's optometric is used to make the proposed receiving wire more exact and proficient. Receiving wire plan enhancement is a term used to depict the way toward further developing the radio wire Model of a microstrip line. The HFSS programming was utilized to imitate the technique. This radio wire is made out of FR4 material, and the conditions for roundabout Patch configuration are presented and approved by all-around reproduced results. This radio wire has a 50-ohm input impedance and is based on an FR4 Epoxy dielectric substrate with a general permittivity of 4.4, a thickness of 1.60mm, and an overall permittivity of 4.4. The fundamental design and low profile characteristics of the recommended radio wire simplify it to deliver and are ideal for use in Wi-Fi organizations.

Purpose Purpose of this study is to design a compact gap coupled anchor shape patch antenna for wireless local area network/high performance radio local area network and worldwide interoperability for microwave access applications. Design/methodology/approach An anchor shape microstrip antenna is conceived, designed, simulated and measured. The anchor shape antenna is transformed to its rectangular equivalent by conserving the patch area. Modeling and simulation of the antenna is performed by Ansys high frequency structure simulator (HFSS) electromagnetic solver based on the concept of finite element method. The simulated results are experimentally verified by using Agilent E5071C vector network analyzer. Theoretical analysis of an electromagnetically gap coupled anchor shape microstrip patch antenna has been performed by obtaining the lumped element equivalent of the transformed antenna. Findings The proposed antenna has a compact conducting patch of dimension 0.26λ × 0.12λ mm2 (λ is calculated at lower resonating frequency of 3.56 GHz) with impedance bandwidths of 100 and 140 MHz and antenna gains of 1.91 and 3.04 dB at lower resonating frequency of 3.56 GHz and upper resonating frequency of 5.4 GHz, with omni-directional radiation pattern. Originality/value In literature, one does not encounter anchor shape antenna using the concept of gap coupling and parasitic patches. The design has been optimized for wireless local area network/worldwide interoperability for microwave access applications with a relatively low patch area (291.12 mm2) as compared to other reported antennas for wireless local area network/worldwide interoperability for microwave access applications. Transformed antenna and the actual experimental antenna behavior varies, but the resonant frequencies of the transformed antenna as observed by theoretical analysis and simulated results (by high frequency structure simulator) are reasonably close, and the percentage difference between the resonant frequencies (both at lower and upper bands) is within the permissible limit of 1-2.5 per cent. Results confirm the theoretical proposition of transformation of shapes in antenna design, which allows a designer to adapt the design shape according to the application.

The aim is to design a Rhombus microstrip patch antenna. The antenna operates at FL=1.447 GHz to FH=2.382 GHz frequency for wireless local area network (WLAN). This antenna operates at f=1.914 GHz resonant frequency. In microstrip patch antenna, many types of shapes like circular, triangular, rectangular, square, ring shape, etc. are used, but in this design a rectangular shape is used. In proposed antenna, the accuracy and efficiency are increased. Integral equation three-dimensional (3D) software (IE3D) is used for the optimize of the rhombus cross-slotted antenna design. The IE3D uses a full wave method of moment simulator. This antenna fabricated on FR4 glass epoxy double-sided copper dielectric material with relative permittivity of ∈ =4.4, thickness h= 1.60mm, and loss tangent is 0.013.

AbstractIn this work, simple, low profile, compact quarter-mode substrate-integrated waveguide (QMSIW)-based antennas are proposed for Wireless Local Area Network (WLAN) at 5.2/5.5 GHz and Wireless Body Area Network (WBAN) at 5.8 GHz, respectively. By implementing QMSIW technique, the electrical size of the antenna is reduced up to 1/4th of the conventional circular SIW cavities. Thanks to the quarter mode concept, the antenna size is reduced significantly by preserving its dominant mode. The resonant frequency of the dominant mode TM010 is independently tuned at 5.2, 5.5, and 5.8 GHz after loading the QMSIW cavity with metalized via holes, subsequently. The on-body performance of the antenna is verified on pork tissues at 5.8 GHz and it is found to be insensitive with respect to surroundings. The measured gain and simulated efficiency of the proposed antenna at 5.8 GHz in free space are 4.8 dBi and 92%, while in the proximity of pork tissues values are 3.25 dBi and 57%, respectively. Moreover, the measurement results demonstrate a good matching with the simulation results.

Low Profile

A low-profile repeater antenna with parasitic elements for on-on-off WBAN applications is proposed. The proposed antenna consists of a planar inverted-F antenna (PIFA), two parasitic elements, and a ground plane with a slot. Due to the slot, the impedance matching of the resonance formed by the PIFA is improved, which makes the proposed antenna operate in the 5.8 GHz industrial, scientific, and medical (ISM) band. To cover the 5.2 GHz wireless local area network (WLAN) band, a dual resonance characteristic is realized by the slot and the two parasitic elements. The first coupling between the PIFA and the slot not only makes the slot operate as a resonator, but also forms secondary coupling between the slot and the two parasitic elements. The two parasitic elements operate as an additional resonator due to secondary coupling. The antenna has the enhanced near surface radiation in the 5.8 GHz ISM band due to addition of the slot and radiation toward off-body direction in the 5.2 GHz WLAN band. In order to evaluate antenna performance considering the human body effect, the antenna characteristics on a human equivalent phantom are analyzed.

Abstract This paper presents a low-profile multi-slotted patch antenna for long term evolution (LTE) and fifth-generation (5G) communication applications. The studied antenna comprised of a stepped patch and a ground plane. To attain the required operating band, three slots have been inserted within the patch. The insertion of the slots enhances the capacitive effect and helps the prototype antenna to achieve an operating band ranging from 3.15 to 5.55 GHz (S11 ≤−10 dB), covering the N77/N78/N79 for sub-6 GHz 5G wireless communications and LTE bands of 22/42/43/46. The wideband antenna presented in this paper offers omnidirectional stable radiation patterns, good gains, and efficiency with a compact size which make this design an ideal contender for wireless fidelity (WiFi), wireless local area network (WLAN), LTE, and sub-6 GHz 5G communication applications.

Planar Monopole Antenna

This paper proposes a planar monopole antenna with a parabolic edge shape. This antenna, which has notch characteristics in the wireless local area network (WLAN) band, can be miniaturized. To obtain the notch characteristics in the WLAN band, a slot with a parabolic edge shape identical to that of the monopole structure was implemented. Because the planar monopole antenna with a parabolic edge shape possesses characteristics similar to those in self-complementary structure conditions, it can be miniaturized by reducing the antenna components at the same proportion. For the antenna fabrication, an FR4 dielectric substrate with a dielectric constant of 4.7 was used. The size of the miniaturized antenna that satisfies the ultra-wide band requirement was 15.6 × 18.6 mm2, and the 10-dB band was 3.013–12.515 GHz. At each frequency, the radiation pattern was similar to that of a dipole antenna.
