“…Nevertheless, it should be emphasized that compared to all other FPAs, our design introduces the filtering characteristics using a very simple CAMS-integrated PRS (one substrate layer with only one type of PRS unit-cell), which is unique among others. As compared to the existing designs with high-gain and filtering features [28], [29], [30], [31], [32], only our FPA achieves RCS reduction.…”

“…Table 1 shows a comparison of the proposed design and the related works, including non-FPA antennas with high gain and filtering performances [11], [12], [13], [14], [15], [16], [17], [28], [29], [30], [31], [32]. It should be noted that this study targets a design with filtering performance, which is often required for narrow band operation so the radiation bandwidth is not a figure of merit in this particular case of comparison.…”

“…Also, the filtering antennas contribute to reduce losses, complexity, size, and cost in microwave devices. For higher gain, the filtering antennas are traditionally arrayed in the previous works, such as [28], [29], [30], and [31], which require complicated feeding networks and design configurations. Recently, a FPA with simple structure has been reported for both filtering and high-gain features [32].…”

A high-gain filtering Fabry-Perot antenna (FPA) with radar cross section (RCS) reduction is proposed. The design utilizes a partially reflecting surface (PRS) which is integrated with a chessboard arranged metasurface (CAMS) in a single-layered substrate. The CAMS is composed of periodic strip arrays to reduce monostatic RCS based on the phase cancellation principle. The PRS structure is a cross-slot array which is designed to work with both orthogonal orientations of the CAMS elements while yielding a high reflection magnitude. Accordingly, the proposed FPA achieves a high-gain broadside radiation and wideband RCS reduction. The filtering functionality is achieved from a T-shaped feed patch, which is, interestingly, enhanced by the integration of CAMS in the PRS. For validation, a prototype operating at 6.0 GHz has been fabricated and measured. The antenna with an overall size of 3.2λ 0 × 3.2λ 0 × 0.57λ 0 at 6.0 GHz exhibits an impedance matching bandwidth (BW) of 5.73−6.23 GHz, a 3-dB gain BW of 5.76−6.17 GHz with the peak gain of 14.63 dBi, and an out-of-band suppression of ≥ 20 dB. Meanwhile, it achieves an RCS-reduction bandwidth of about 4.0 to 9.0 GHz (76.9%).INDEX TERMS Fabry-Perot antennas (FPA), partially reflecting surface, radar cross section, chessboard arrangement, polarization conversion, filtering antenna.

“…Also, this structure reached a 31%-40% size reduction compared to a conventional square patch. Filtering or band notch patch structures are also used to band suppression and control the multiple transmission [19][20][21]. This proposed DGS area is more compact than other published related papers in this article.…”

To suppress higher order harmonic using Inverted “U” shapes defected groundstructure (DGS) with two symmetric inverted “L” shape stubs is presented here.At first, a study was made on the resonant frequencies of traditional line feedmicrostrip antenna. An Inset feed with inverted slots is introduced to eliminateall the higher-order modes up to the third harmonics in the WiMAX Band.To get wide-area stopband characteristics, dimensions and position of DGS andstubs are optimized. The proposed DGS area along with the radiated patch ismore compact and stable rather than in a few reported articles. This microstripantenna is designed and perfectly matches the WiMAX frequency band (3.3-3.7GHz) application while suppressing other frequencies. The proposed inverted‘U’ shapes DGS are designed with an equivalent circuit. Finally, the proposedStub with DGS Antenna(SDA) is fabricated and measured. The proposed structure is verified with measurements and it has satisfactory gain, radiation patternand reflection coefficient at 3.5 GHz. The results illustrate that the antenna hassatisfactorily gained
