“…To clearly show the advantages and high performance of the proposed design, comparisons with other state-of-theart designs are conducted. Firstly, compared to the previous dual-polarized filtering antennas [2]- [14], the proposed FPA achieves a much better gain and isolation while having comparable suppression level. The proposed design's bandwidth of 17.1% is also considered as wide and sufficient for many applications.…”

“…Dual-polarization is necessary for base station in cellular systems because it mitigates multipath fading effects and increases channel capacity. Accordingly, dual-polarized filtering antennas [2]- [14] have received much attention in recent years. Furthermore, in order to directly connect to differential RF/microwave circuits without additional balun, differential-feed scheme has applied to the dual-polarized filtering antennas [15]- [21].…”

In this paper, a dual-polarized filtering Fabry-Perot antenna (FPA) with high-isolation is proposed. It consists of a feed element of differential-fed dual-polarized square patch and a partially reflecting surface (PRS). The patch is capacitively coupled with T-shaped resonators and shorting-vias to obtain broadband characteristic and radiation nulls. The PRS structure is composed of two complementary metasurface layers are selected for achieving a positive reflection phase gradient within the broad frequency range. More interestingly, thanks to the frequency selectivity feature, the PRS significantly enhances the filtering characteristic of the FPA. For verification, a prototype of the proposed antenna operating at the 5.5-GHz center frequency has been fabricated and measured. The prototype with an overall size of ∼2.0λ min × 2.0λ min × 0.49λ min (λ min is the free-space wavelength referring to the lowest operational frequency) result in an impedance bandwidth of 17.1% (5.02 − 5.96 GHz) for 10-dB return loss and a high isolation of ≥ 45 dB. Moreover, the far-field measurements result in a good dual-polarized radiation with the peak gain of 13.0 dBi, cross-polarization level of ≤ -25 dB within the passband, and out-of-band suppression level of ≥ 20 dB.

“…Recently, direct modifications to the antenna radiation structure have been used to solve these issues. [5][6][7][8][9][10][11] Examples include etching slot in Chen and colleagues, [5][6][7] using multiple patches in Yuan and colleagues, 8,9 and moving the coupled feed line in Zhang et al 11 All of these have the ability to alter the antenna's surface distribution current, cancelling the far-field radiation at a particular frequency to produce the filtering effect. Due to the absence of the filtering circuit, the antenna structure is more straightforward.…”

A compact high‐gain filtering patch antenna with harmonic suppression characteristic is proposed. The antenna mainly contains a coupled transmission line and a central rectangular patch. The capacitive coupling between the coupled transmission line and the rectangular patch generates a radiating null at high frequencies. Then, acrossing the hybrid coupling principle, the structure of the microstrip‐to‐slotline transition builds two coupling paths, which generate a radiating null at low frequencies. In addition, two vertical slots are carved into the rectangular center patch to truncate the lateral current. That removes the higher order resonant modes and suppresses the parasitic passbands at high frequencies outside the passband. A fabricated 2 × 2 filtering antenna array is measured, showing a bandwidth up to 3.9% (8.68–9.03 GHz), a peak gain of 14.43 dBi, and two near‐band radiation nulls located at 8 and 9.55 GHz, demonstrating good radiation performances and an isolation of 25 dB.

“…To meet the needs of users, dipole antennas are widely used in base station antennas [1,2,3,4,5]. The advantages of the dual-polarized antenna are wideband, multi-frequency, and multi-mode, which can be used to resist channel attenuation and increase channel capacity [6,7,8,9]. At the same time, in order to save the space resources of the base station, miniaturization of the antenna is required.…”

A low-profile wideband dual-polarized antenna with nonuniform metasurface is proposed for 2G/3G/4G/IMT applications. The proposed antenna maintains broad bandwidth and stable gain but has a low profile of only 0.17λ0 at 2.0 GHz, which contributes to the metasurface designed above the radiator. The nonuniform circular elements of the metasurface are set to reduce the coupling between each element, thus stable radiation patterns and low cross-polarization levels can be realized. The test results show a wide impedance bandwidth range from 1.4 GHz to 2.79 GHz (66.3%) for |S11| < -10 dB and high isolation is more than 27 dB. The measured stable gain is 9±1 dBi. In the entire frequency band, stable radiation patterns are achieved with low cross-polarization levels below -18 dB.
