“…Our design for the size and thickness of the unit cell in the FSS is of subwavelength, making it a metasurface design. In an earlier work, I‐shaped unit cell has been used as mushroom‐like EBG on MPA 17 and as FSS superstrate 18 to enhance the gain. In Reference 17, they have simulated the design and then validated it by measurement, whereas in Reference 18, the use of I‐shaped unit cell as superstrate is presented only using the simulated results.…”

A compact, high gain, single layer substrate-superstrate configuration based Fabry-Perot cavity (FPC) microstrip patch antenna (MPA) is designed. It consists of a single-frequency MPA on a substrate, along with a frequencyselective surface (FSS) which acts as a metasurface-superstrate. The FSS contains a periodic arrangement of unit cells in a square lattice, where each unit cell is structured by a simple design of H-shape. It works as a partially reflecting surface and is used as a superstrate by mounting the FSS layer over the conventional patch antenna using a Teflon spacer. Our design of single layer and single resonance FSS structure is used to obtain triple-band resonance on loading it as a superstrate on the MPA. The enhanced reflection phase of FSS plays a key role in obtaining triple-band performance. The relationship between the cavity height and the cavity resonance frequency is the foremost reason to achieve triple-band FPC-MPA from a single resonance MPA. The prototype antenna is fabricated, and the measured results show that the FPC antenna yields a peak gain of nearly 9.30, 10.00, and 9.60 dB at 8. 90, 9.63, and 11.49 GHz, respectively in broad-side direction in both the planes.Gain enhancement of nearly 6, 4.50, and 5.50 dB, in all the three bands are achieved in both the planes, emphasizing the effect of stacking the superstrate on the conventional patch antenna. The triple-band frequency response shows 3 dB gain bandwidths of 11.79%, 11.45%, and 9.56% at the three frequencies. A significant improvement in impedance bandwidth has been achieved in the measurements in all the three frequency bands, with the highest bandwidth improvement of 6.71% of the FPC antenna at 11.49 GHz. It is also reconfigurable as its operating frequency can be tuned within the X-band (8-12 GHz) range by a small change in the spacer thickness. In addition, it shows rotation angle-independent performance features.

This paper mainly deals with performance comparison of various EBG antennas for WIFI applications.The proposed designshave a size of 28.11x32.40x1.59 mm3with RT / Duroid 5880 substrate having a thickness of 1.59mm and Ɛr = 2.2. In recent years the use of electromagnetic band gap structures, has grown rapidly in the antenna designs due to its unique properties. EBG structures are used in the antenna to enhance its performance characteristics. In this paper variousEBG antennasare designed and replicated using HFSS software. Various EBGs like Fork, Fractal, Spiral are placed on Ground plane and on the patch. Performance parameters such as return loss, radiation patterns and Gain are measured and are reported.

“…Further trade off exists between gain and bandwidth of the patch antenna. Several gain and bandwidth enhancement or broad banding techniques has been reported in the literature, such as multilayer patches [1], coplanar directly gap-coupled patches [2], proximity coupling [3], defected ground structures [4], loading of shorting pins in the radiating patch [5] and EBG structures [6,7].…”

In this paper a compact multilayer stacked patch antenna with high gain is proposed. The structure is composed of stacked patches with U slots and shorting pins. The proposed antenna is capable for resonating at the center frequency of 2.25 GHz. The performance of the antenna is characterized by the simulated result of bandwidth, gain and reflection coefficient. The antenna has reflection coefficient of less than -10 dB with a maximum gain of 7.07 dBi. The proposed antenna has bandwidth of nearly 400MHz and has less size with an overall height of 10.3 mm. The designed frequency range occupies S band which is used for various applications like weather radar, surface ship radar, Bluetooth and ZigBee.
