High gain planar antenna using optimised partially reflective surfaces

Abstract-This paper presents a high-gain cavity resonant antenna (CRA), consisting of an FSS layer placed above an aperture coupled microstrip patch antenna (ACMPA). Geometry of the proposed FSS superstrate is highly reflective with |Γ > 0.9|. Ray-tracing method has been employed for determining the resonant condition of the antenna. ACMPA operating at S-band is serving as a feeding source. The coupling aperture of the antenna is of novel design, and several figures of merit have been presented for the proposed coupling aperture. Analysis of CRA has been carried out with the design parameters of the CRA. HFSS-13 has been utilized as simulation tool. Measured results are in good agreement with the simulated ones.

“…A highly reflective superstrate layer is the key part of CRA of high gain and directivity [1] and [6].…”

A Novel Design Approach for a 60 GHZ Circularly Polarized Ebg Antenna

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.

“…The partially reflecting sheet arrays were firstly introduced to antenna design by Trentini in 1956 [3], and then referred to as "Fabry-Perot cavity antennas (FPCAs)" by Feresidis and Vardaxoglou [4]. FPCAs provide several advantages of low complexity feeding network, high gain, and compatibility with the printed circuit board (PCB) process [5].…”

A Dual-Polarized Fabry-Perot Cavity Antenna at Ka Band With Broadband and High Gain

et al. 2015

Abstract-A broadband Fabry-Perot cavity antenna (FPCA) operates at Ka band with high gain and dual-polarization is reported. The proposed antenna employed a double-sided complementary-circular partially reflective surface (PRS) to enhance the directivity bandwidth. A square patch coupled by two orthogonal slots and fed by two microstrip lines was applied as the primary feed to achieve dualpolarization operation. To further improve the impedance bandwidth and directivity, a series of metal vias were suggested to surround the primary patch. This FPCA design was verified by the measurements. The experimental results show that the common impedance bandwidth of the two ports for the reflection coefficient (S 11 ) below −10 dB is 2.5 GHz from 34 GHz to 36.5 GHz (7.1%), which covers the common 3 dB gain bandwidth of the two ports. At the center frequency of 35 GHz, the measured peak gains at the two orthogonal ports are 16.1 dBi and 15.1 dBi, respectively. The isolation between the two ports is higher than 30 dB within the bandwidth.
