The objective of the paper is to design and investigate a rectangular microstrip antenna that covers the band from 2.4 to 3.6 GHz. The proposition consolidates investigation of fundamentals of microstrip patch antenna. A progression of simulation in Ansoft HFSS (High Frequency System Simulation) has been carried out to discover the dual operating frequency. The qualities of the patch antenna rely on its different geometrical parameters. The investigation is carried in terms of two prime factors: Return loss and radiation pattern.

The microstrip antenna required for higher frequency application is to be light in weight, easy to fabricate and small in size. As the applications in S-band and Ku-band are increasing with the increase in technology the requirement for higher data rate so the proposed work is to design a 24GHz (ka band) rectangular microstrip antenna with stripline feeding, return loss to be less than -20dB and VSWR less than 0.5. The substrate is chosen to be RT/duroid 5880 with relative permeability 2.2. it is capable of covering satellite application, telemetry. HFSS software tool is used to design the antenna.

Rectangular Microstrip Antenna

In this work, a simulated study was carried out for designing a novel spiral rectangular patch of microstrip antenna that is used in ultra-wideband applications by using a high frequency structure simulator software (HFSS). A substrate with dielectric constant of 4.4 and height 2.10 mm (commercial substrate height available is about 0.8-1.575 mm) has been used for the design of the proposed antenna. The design basis for enhancing bandwidth in the frequency range 6.63 - 10.93 GHz is based on increasing the edge areas that positively affect the antenna's efficiency. This design makes the designed antenna cost less by reducing the area of the patch. It has been noticed that the bandwidth of the antenna under this study is increasing to 4.30 GHz or 61% compared with 3.6% for the standard rectangular microstrip antenna with the same dimensions of the proposed antenna. The antenna also maintains the voltage standing wave ratio of 1.09 at resonant frequency 7.07 GHz, return loss -27.07 dB, and the amount of impedance in real and imaginary parts 51.5Ω and 3.3Ω, respectively.

<p>This paper presents Dual-Band proximity coupled feed rectangular Microstrip patch antenna with slots on the radiating patch and Defected Ground Structure. Initially a simple proximity coupled feed rectangular Microstrip patch antenna resonating at 2.4 GHz is designed. Etching out a ‘Dumbbell’ shaped defect from the ground plane and ‘T’ shaped slot from the radiating patch of the proximity coupled feed rectangular Microstrip patch antenna, results in a Dual-Band operation, i.e., resonating at 2.4 GHz and 4.5 GHz; with 30.3 % and 18.8% reduction in the overall area of the patch and the ground plane of the reference antenna respectively. The proposed antenna resonates in S-band at frequency of 2.4 GHz with bandwidth of 123.6 MHz and C-band at frequency of 4.5 GHz with bandwidth of 200 MHz, and a very good return loss of -22.1818 dB and -19.0839 dB at resonant frequency of 2.4 GHz and 4.5 GHz respectively is obtained. The proposed antenna is useful for different wireless applications in the S-band and C-band.</p>

A novel butterfly-shaped patch antenna for wireless communication is introduced in this paper. The antenna is designed for wideband wireless communications and radio-frequency identification (RFID) systems. Two symmetrical quasi-circular arms and two symmetrical round holes are incorporated into the patch of a microstrip antenna to expand its bandwidth. The diameter and position of the circular slots are optimized to achieve a wide bandwidth. The validity of the design concept is demonstrated by means of a prototype having a bandwidth of about 40.1%. The return loss of the butterfly-shaped antenna is greater than 10 dB between 4.15 and 6.36 GHz. The antenna can serve simultaneously most of the modern wireless communication standards.

This paper presents the design of a dual-band microstrip patch antenna for Wi-Fi that operates at 2.5 GHz and 5.8 GHz. The antenna contains a rectangular patch with two rectangular slots. The first slot is incorporated in the patch while the second slot is incorporated in the ground plane. The antenna is based on a microstrip fed rectangular patch printed on the FR-4 epoxy substrate with a dielectric constant of 4.4 and a thickness of 1.6 mm with patch size 24 mm × 21 mm. The simulated result shows that the realized antenna successfully works on dual-band and subsequently achieves a bandwidth of 100 MHz and 200 MHz as well as the return loss about -29.9 dB and -15.16 dB for 2.5 GHz and 5.8 GHz respectively. A stable omnidirectional radiation pattern is observed in the operating frequency bands. The antenna meets the required specifications for 802.11 WLAN standards.

Microstrip Patch

A microstrip patch antenna is designed for a wearable antenna. The performance of microstrip patch antenna loaded with reactive impedance surface (RIS) is described in terms of gain, bandwidth and return loss. The antenna is investigated in two conditions which are conventional microstrip antenna with RIS and without RIS. The designed antenna is also aimed at size reduction therefore it will be suitable for a wearable application. This antenna which is made fully using textile and it is designed for operation in the 2.45 GHz band. The performance of microstrip patch antenna loaded with RIS is described in terms of gain, bandwidth, return loss and radiation pattern. The antenna designed with RIS operates at 2.45 GHz. Bandwidth enhancement is achieved with RIS where the designed antenna can cater frequency from 2.4 GHz to 3 GHz. A gain enhancement is achieved of 20% is achieved compared with the conventional patch antenna. Although the size of the patch is reduced with the introduction of RIS, the overall size of the antenna with the substrate is almost similar to the conventional patch antenna. However, the performance of the antenna is greatly enhanced with the use of RIS.
