“…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.

“…The filtering characteristics of the first type of filtenna mainly depend on the IBFC-based feed network, including bandwidth, gain selectivity, and out-of-band suppression. Different types of filtering circuits such as resonant cavity [23]- [32], microstrip resonator [33]- [45] and reconfigurable resonator are embedded in the feed network to obtain band-limited radiation characteristics. It should be noted that the bandwidth of the filtering circuit is usually narrower than the operating bandwidth of the radiating element to ensure proper system function within the desired frequency band [56].…”

The fifth generation (5G) mobile communication systems employ technologies such as massive MIMO, millimeter-wave (mmWave), and ultra-dense networks to support higher transmission data rate and lower latency, thereby enabling commercial deployment. Furthermore, the forthcoming sixth generation (6G) networks will integrate terrestrial and non-terrestrial networks, aiming to achieve full spectrum, full applications, and global coverage. Whether in the context of 5G or 6G networks, base transceiver stations (BTS) require a substantial number of radio frequency (RF) transceiver chains and antenna array, particularly in mmWave frequency bands. It is known that bandpass RF filters between antenna elements and transceivers are key components for suppressing out-of-band spurs and interference. The single board seamless integration of transceivers and antennas has become a growing trend. It means there is no extra room for a large number of filters at mmWave bands, leading to the emergence of integrated designs that combine filtering circuitry with antennas, known as filtenna or filtering antenna. With illustrated examples, the design methodologies, operational principles, and implementation strategies of filtennas are reviewed in this paper.

“…However, the gain variation of a single-mode OAM beam is rarely discussed in the frequency domain. The gain-filtering characteristic can enhance the accuracy and sensitivity of OAM communication and sensing, releasing the pressure on filtering circuit designs in transmitting/receiving chains [40,41].…”

A 3D transmitarray (TA) is proposed to generate dual-polarized orbital angular momentum (OAM) beams with gain and mode purity filtering responses. The TA units are realized by square cavity filters with the same passband and different orders and inner widths, resulting in different coupling cavity numbers. The evanescent modes in the coupling cavities will greatly decrease the propagation constant, thus generating a large phase variation. The square structure of the cavity filter makes it able to support dual-polarized wave propagation with the same phase delay and insert loss. Based on these transmission characteristics, eight different TA units are designed to realize a 3-bit phase gradient within the passband of 25.4 GHz to 26.7 GHz. It should be emphasized that the dispersed transmission phase and magnitude of the eight TA units in the stopbands will deteriorate the purity of the OAM beam. Therefore, the gain and mode purity filtering responses can be realized simultaneously. In order to verify the performance of the proposed OAM TA design, a TA prototype with the mode number l = -1 is fabricated by 3D printing technology. The TA can realize the maximum gain of 25.9 dB in the passband, and the rejection level is below –15.0 dB within the main beam direction. The purities of dual-polarized OAM beams are over 0.5 in the passband, and the cross-polarization is below –16.5 dB. The advantages of the OAM TA, including gain-filtering and mode purity-filtering responses, dual-polarization, and high efficiency make it a promising solution for millimeter-wave OAM sensing and communication applications.
