“…Non-coplanar parasitic structures are commonly employed by superimposing an additional metallic surface above the radiating aperture, encompassing configurations such as stacked patches [165]- [170], resonant structure [171]- [174], metamaterial [175], near-field parasitic antenna [176][177], vias [178], and the like. The stacked patch technique facilitates the attainment of favorable electrical performance across wide bandwidths, consequently rendering it extensively applicable in bandwidth enhancement.…”

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.

“…There have been a multitude of works that have employed various methodologies to design dual‐band dual‐polarized antennas, 1–9 which have achieved wide bandwidths in both bands. To improve spatial efficiency and achieve a more compact design, some researchers have utilized embedded or superimposed shared‐aperture antennas for dual‐band and dual‐polarization capabilities 3–9 . Additionally, filtering structures, 4,7–9 or frequency selective surfaces (FSSs) 3,6 have been incorporated to reduce the impact of mutual coupling among different frequency elements.…”

A dual‐band and dual‐polarized antenna based on a dual‐layer metasurface (DMTS) is proposed for 5G application. The proposed DMTS is designed on two substrates separated by an air loading layer using characteristic mode analysis (CMA). The upper metasurface (MTS) is an array of 4 × 4 square patches, while the lower MTS consists of a central rectangular patch and four parasitic patches. The DMTS is fed by a pair of orthogonal Y‐shaped microstrip line at its bottom through the I‐shaped slots located over them, while the loading slots are etched directly below the parasitic patch to effectively excite the edge portion. The proposed antenna offers −10 dB bandwidths of 13.6% (2.46–2.82 GHz) and 20.3% (3.18–3.9 GHz) and realizes peak gains of 9.53 and 10.9 dBi with an overall size of 0.88λ0 × 0.88λ0 × 0.057λ0 (λ0 is the free‐space wavelength of the center frequency at lower band), as well as an interport isolation of over 35 dB.

SummaryThis paper presents two different configurations of ±45° dual‐wideband dual‐polarized (DWDP) antennas. The antenna comprises eight end‐loaded broadband dipoles grouped into two sets based on the bands of operation. The high‐frequency dipoles are strategically placed within the low‐frequency ones to form the elementary unit. Further optimization has been performed on the elementary unit in terms of the radiator placement to suppress sidelobe levels for array formation. Both configurations are meticulously fabricated using an all‐metal structure, demonstrating durability and the simplicity of fabrication. The antenna designs achieve ±45° polarization, high gain, satisfactory cross‐polarization discrimination (XPD), and wide impedance bandwidth covering 0.67–1.04 GHz and 1.54–3 GHz bands. Despite the nested configuration, mutual coupling is well within acceptable limits. Formation of the array based on the optimum elementary unit has been investigated by simulation, revealing reasonable gain enhancement and low sidelobe levels across all bands. This comprehensive approach yields a robust, high‐performing antenna configuration suitable for indoor distributed antenna system (IDAS) applications.
