“…the pattern changes from broadside to sectorial and then to conical for different frequencies in the band as shown in Fig. 6 (for a superstrate size of 2 0 & h 2 =0.6 0 ), which may suitable for some other application (Vettikalladi et al, 2009b). Here, the small superstrate size is due to the presence of the parasitic patch that disturbs the field in the cavity (thickness = 0.6 0 ).…”

“…Although DRA also has several drawbacks such as low gain and limited bandwidth, various gain enhancement methods of DRA have been reported such as using an antenna array [5], a superstrate structure [6], or using short horns around DRA [7]. The requirement to use circularly polarized antennas to obtain the required performances is linked to the fact that the techniques for a circular polarized DRA are still limited.…”

Abstract-This article focuses on the development of a high gain, broadband, circularly polarized Electromagnetic Band Gap (EBG) antenna operating at 60 GHz. The designed antenna is configured with a superstrate based on a frequency selective surface (FSS) placed in front of a cross dielectric resonator antenna (XDRA), installed into a ground plane, which acts as an excitation source. A fast Leaky-Wave approach based on transverse equivalent network (TEN) is used to deduce analytical radiation patterns formulas of the proposed antenna. The proposed analytical model was implemented and verified by a comparison with both numerical and experimental results. The reported results showed very satisfactory performances with an achievable impedance bandwidth (S 11 < −10 dB) of 11.7% from 56 to 63 GHz, an axial-ratio bandwidth (AR < 3 dB) of 5.4% from 58.9 to 62.1 GHz and a stable gain of 16.7 dBi within the passband. A good agreement among analytical, numerical and measured results is successfully achieved and falls well within initially set specifications.

“…There are several configurations for the design of superstrate layer which have been attempted in past. This includes the use of simple dielectrics [3], electromagnetic band gap structures [4], artificial magnetics [5] and highly reflective frequency selective surfaces (FSS) [6,7]. The technique of using a highly reflective frequency selective surfaces (FSS) for directivity and gain enhancement has been proved quite effective [7][8][9][10].…”

Abstract-Cavity reflex antenna (CRA) employing a circular patch type FSS (Frequency Selective Surface) superstrate is investigated. Analysis in terms of gain, bandwidth (impedance and gain) and radiation pattern has been presented. The aim of this work was to study low profile CRA having very thin superstrate sizes. In this CRA a circular patch antenna is used as a feeding source. The circular patch type FSS possesses some unique properties favorable for thin superstrate sizes. In practice when the excitation source of the CRA is a probe-fed microstrip antenna with finite ground plane, substrate and superstrate, cross-polarization increases. In the presented design, the cross polar level has been reduced by choosing the optimum air gap and superstrate geometrical and electrical properties. A CRA with circular patch type FSS offers better performance both in terms of gain and impedance bandwidth for, thin superstrates (0.008λ 0 ) while giving a gain of 13 dBi and considerably reduced crosspolar level. The proposed antenna exhibit nearly equal E-plane and H-plane radiation pattern. Measurement results are provided to support the simulated results (by Ansoft HFSS). The circular patch type FSS is easy to fabricate and can be embedded into the host profile.
