In this work, a broadband high gain frequency selective surface (FSS)-based microstrip patch antenna is proposed. The dimensions of the microstrip antenna and proposed FSS are [Formula: see text] and [Formula: see text]. A broadband high gain reference antenna has been selected to improve antenna performance. The reference antenna offers 1.2[Formula: see text]GHz bandwidth with 6.03[Formula: see text]dBi peak gain. Some modifications have been done on the patch and ground plane to enhance the bandwidth and gain. The impedance bandwidth of 7.70[Formula: see text]GHz (3.42–11.12[Formula: see text]GHz) with 4.9 dBi peak gain is achieved by the microstrip antenna without FSS. The antenna performance is improved by using FSS beneath the antenna structure. The maximum impedance bandwidth of 7.70[Formula: see text]GHz (3.32–11.02[Formula: see text]GHz) and peak gain of 8.6[Formula: see text]dBi are achieved by the proposed antenna with FSS. Maximum co- and cross-polarization differences are 21[Formula: see text]dB. The simulation and measurement have been done using Ansoft Designer software and vector network analyzer. The measured results are in good parity with the simulated one.

This research article gives a detailed insight of the design, simulation of a compact circular shaped microstrip patch antenna that is fed using a coplanar waveguide feed (CPW for practical wireless communication applications). The antenna is typically designed for Ultra wideband (1.46-6GHz), Bluetooth (2.4GHz), ZIGBEE (2.4GHz), WLAN (5.15- 5.35 GHz and 5.725- 5.825), Wi-Fi (2.4-2.485GHz) and HIPERLAN-2(5.15 - 5.35 GHz and 5.470 -5.725GHz) wireless applications with stop band characteristics for the H (partial C band). The proposed antenna has an overall packaged structure dimensions of 78 x75 x1.605 mm3 and is fabricated on FR4 substrate as a circular patch antenna with a coplanar ground .The commercially available laminate FR4 substrate that is used has a dielectric constant of 4.4, height of 1.6mm and a loss tangent of 0.0024.The prospective antenna shows a simulated impedance bandwidth of 4.54 GHz. The coplanar waveguide feeding used with this antenna helps in improving antenna performance in terms of its impedance bandwidth as this geometry helps in creating multiple current loops at the antenna structure, thereby exciting nearby frequencies that merge to show a broadband of operation. The antenna’s operational bandwidth is also improved by the concept of modified ground, in which triangular and rectangular shapes are added symmetrically on both sides of ground plane that provide a better fringing effect and hence an improved bandwidth.

This paper presents a simple broadband planar monopole microstrip patch antenna with curved slot and partial ground plane. The proposed antenna is designed and fabricated on commercially available FR4 material with εr = 4.3 and 0.025 loss tangent. Bandwidth enhancement has been achieved by introducing a curved slot in the patch and optimizing the gap between the patch and the partial ground plane and the gap between the curved slot and the edge of the patch. Simulated peak gain of the proposed antenna is 4.8 dB. The impedance bandwidth (defined by 10 dB return loss) of the proposed antenna is 109% (2–6.8 GHz), which shows bandwidth enhancement of 26% as compared with simple monopole antenna. The antenna is useful for 2.4/5.2/5.8-GHz WLAN bands, 2.5/3.5/5.5-GHz WiMAX bands, and other wireless communication services. Measured results show good agreement with the simulated results. The proposed antenna details are described and measured/simulated results are elaborated.

This work builds a metamaterial (MTM) superstrate loaded on a patch of microstrip antenna for wireless communications. The MTM superstrate is made up of four G-shaped resonators on FR-4 substrate with a relative permittivity of 4.4 and has a total area of (8×16) mm2, and is higher than the patch. The MTM superstrate increases antenna gain while also raising the input reflection coefficient. When it is 9 mm above the patch, the gain increased from 3.28 dB to 6.02 dB, and when it is 7 mm above the patch, the input reflection coefficient was enhanced from -31.217 dB to -45.8 dB. When the MTM superstrate loaded antenna was compared to the traditional unloaded antenna, it was discovered that metamaterials have a lot of potential for improving antenna performance.

<p>This paper presents the bandwidth enhancement of a Proximity Coupled Feed Rectangular Microstrip Patch Antenna using a new Defected Ground Structure - an ‘inverted SHA’ shaped slot on the ground plane of the proximity coupled feed rectangular Microstrip patch antenna. The parameters such as Bandwidth, Return loss, VSWR and Radiation efficiency are improved in the proposed antenna than simple proximity coupled feed rectangular Microstrip patch antenna without Defected Ground Structure. A comparison is also shown for the proposed Microstrip patch antenna with the antenna structure without Defected Ground Structure. The proposed antenna resonates in S-band at frequency of 2.4 GHz with bandwidth of 180 MHz. A very good return loss of -47.9223 dB is obtained for the Microstrip patch antenna with an ’inverted SHA’ shaped Defected Ground Structure. Implementing an ‘inverted SHA’ shaped defect in the ground plane of the proximity coupled feed rectangular Microstrip patch antenna results in 5.3% improvement in bandwidth with 16.01% reduction in the overall area of the ground plane as compared to the Microstrip patch antenna without Defected Ground Structure.</p>

Antenna Performance

The microstrip patch antenna is used in various communication applications including cellular phones, satellites, missiles, and radars, due to its several attractive features such as small size and weight, low cost, and easy fabrication. The microstrip patch antenna consists of a top radiating patch, a bottom ground plane, and a dielectric substrate in between. The patch can have different shapes, the rectangular patch being the most commonly used. In practice, the microstrip antenna suffers from narrow bandwidth and low gain efficiency. This paper aims to enhance the bandwidth and efficiency of a rectangular-patch antenna using the High-Frequency Structure Simulator (HFSS). Initially different patch sizes and substrate materials are investigated and optimal antenna parameters are achieved. Then, the antenna performance is further enhanced by inserting single and double slot designs into the patch. Two cost-effective feeding methods are involved in the investigation. The antenna is designed to operate in the Super High Frequency (SHF) band.

Abstract In this paper, a Tri-band microstrip-line-fed low profile microstrip patch antenna is proposed for future multi-band 5 G wireless communication applications. The proposed antenna is printed on a compact Rogers RT5880 substrate of dimensions 20×16.5×0.508 mm3 with relative permittivity, εr of 2.2 and loss tangent, tan δ of 0.0009. To improve return loss and bandwidth of the proposed antenna, a partial ground plane technique is employed. The proposed antenna operates at 10, 28, and 38 GHz, three of the selected frequencies which are allocated by the International Telecommunication Union (ITU) for 5 G mobile communications. To reduce interference between the 5 G system and other systems in the band, a pair of T-shaped slots is etched in the radiating patch to reject unwanted frequency bands. The proposed design provides a gain of 5.67 dB at 10 GHz, 9.33 dB at 28 GHz and 9.57 dB at 38 GHz; the radiation pattern is mostly directional. The proposed antenna is designed and optimized using two commercial 3D full-wave software, viz. CST microwave studio and Ansoft HFSS. A prototype of the designed antenna that was fabricated and showed good agreement between the actual measurements of S11 & VSWR and the simulation results using both software.
