“…PRS in literature 18,19 is traditional dielectric superstrate. Among them, the feed used in reference [18] is a 2 Â 2 CP circular patch array antenna fed by sequential rotation feeding network. A simple wideband stacked patch antenna that operates at X-band (8 GHz -12 GHz) is used as a radiation source to expand the bandwidth of the traditional patch antenna with truncated corners in.…”

“…Since the wavelength-frequency curve contributes a negative slope for formula (1), to enable the antenna achieve a broadband with a constant cavity height, the slopes of φ p -and φ g -frequency curves should be with positive slopes. For example, the reference [18] utilized a high-impedance ground plane, which provided a positive slope for the reflection coefficient phasefrequency curve, aimed at the bandwidth enhancement of the resonant cavity antenna.…”

“…To improve the gain performances of antenna, the Fabry-Perot (F-P) resonant cavity antenna was proposed, while some achievements have been obtained with the in-depth study of numerous scholars. For the application of CP antennas, the Fabry-Perot (F-P) resonant cavity antenna can efficiently increase the gain of the original CP patch antenna by loading partial reflecting surfaces (PRS) in the maximum radiation direction [6][7][8][9][10][11][12][13][14][15][16][17] Although there exist so many researches, the inherent narrow-band effect of F-P resonant cavity antennas and the negative reflection coefficient phase slope of traditional dielectric PRS [18][19][20] make them difficult to adapt to modern antenna broadband application scenarios. On the other hand, frequency selective surface (FSS), 21 which is widely used in antenna systems, provides a novel train of thought for the design of CP F-P resonant cavity antenna.…”

This paper designed a circularly polarized (CP) Fabry-Perot (F-P) resonant cavity antenna which utilized a frequency selective surface (FSS)-based partial reflecting surface (PRS). The loading thin single-layer FSS-based PRS is composed of patches on the top layer of the substrate and square loop slots on the bottom. With the obtained positive slope for the reflection coefficient phase of the loading PRS, the operating bandwidth of the F-P resonant cavity antenna is expanded. In order to further expand the bandwidth, we introduced a sequentially rotating feeding network to excite a 2 Â 2 CP patch array, which is used as a feed source for the resonant cavity antenna. By experiment, the actual measured |S11| < À10 dB impedance bandwidth is 26.9%, while the 3-dB axial ratio (AR) bandwidth is approximately 17%. A maximum gain of 15.4 dBic and a radiation efficiency is 86.8% are achieved, which indicate that the proposed antenna is a promising candidate for CP communication applications.
