“…e profile in [18] is low, but the size is a little large. Compared with [18,19], the proposed antenna could cover the most frequency bands for sub-6 GHz communications. For the simulated radiation efficiency in the operating band, the minimum value is 91.62% at 3.60 GHz while the maximum value is 95.19% at 3.40 GHz, which exhibits the advantage of the proposed antenna because of the lossy substrate [20,21].…”

A dual-band base station antenna is introduced in this paper. The proposed antenna is composed of baluns, bowtie patches, and a split ring. The two pairs of bowtie patches excited by the two orthogonal balun structures can achieve dual polarization. The split ring is used to yield two additional resonances to broaden the impedance bandwidth. In this way, a compact dual-band base station antenna is obtained with the size of 0.41 λc × 0.41 λc × 0.13 λc (λc is the wavelength in the free space at the lowest operating frequency band) and the average gain of 8.2 dBi. Moreover, the operating frequency bands of the proposed antenna cover 2515–2675 MHz, 3400–3600 MHz, and 4800–5000 MHz, which can function as an element for macro- or microcells in sub-6 GHz communications.

“…It can be seen from the Table 2 that this proposed antenna has the widest operating bandwidth, relatively high gain, and a small size. Although Fu et al 6 has an approximate bandwidth, it has a larger aperture size compared with the proposed antenna. As such, the performance advantages mentioned prompt the proposed antenna a good candidate for UWB CP with a small aperture and unidirectional patterns.…”

“…In addition, dual polarization can increase channel capacity and achieve polarization diversity to reduce the impact of multipath fading. Therefore, wide band/multiband, dual polarized, and compact antennas have become a research focus in the field of wireless communication 4–6 . A dual‐polarized antenna composed of four vertical monopoles and four horizontal dipoles is proposed in Ta et al, 7 which has an operating frequency band of 1.7–3.9 GHz (78.6%).…”

Design of ultra‐wideband (UWB) dual‐polarized magnetoelectric (ME) dipole antenna with compact size is presented. The proposed antenna consists of a double‐layer ME dipole, a pair of cross‐placed Γ‐shaped probes, and a box‐shaped reflector. Total size of the final design is 95 mm (0.87λ0) × 95 mm (0.87λ0) × 65 mm (0.6λ0). Both simulated and measured results show that the proposed antenna has an operating bandwidth of 127.3% (1–4.5 GHz) with voltage standing‐wave ratio (VSWR) ≤ 2.2 and 5.1 dBic ≤ gain ≤ 9.6 dBic. A stable unidirectional radiation pattern is achieved over the whole band. The cross‐polarization level is less than −15 dB and isolation between two ports exceeds 15 dB. Due to its compact size and good performance, the proposed antenna can be a competitive candidate in most wireless communication application scenarios.

“…The isolation between ports is a critical parameter, specially when multiple-port solutions are mounted in limited space scenarios. Some of the techniques used for increasing isolation are based on using a decoupling element [10], a neutralization line [11], orthogonal polarizations [12]- [17], decoupling networks [18] and self-isolated/self-decoupled [19]- [21] antennas. In addition, the interest on Characteristic Modes Analysis (CMA) in modern applications [22] has increased due to the possibility of exciting different orthogonal modes on a radiating ground plane of a hand-held device for MIMO compatibility.…”

A four-port wideband cavity-backed antenna is presented for indoor base stations applications. The antenna is composed of a square open cavity with an X-shaped isolating block and 4 feeding monopoles symmetrically and orthogonally arranged in the aperture of the cavity. A novel methodology based on Characteristic Modes Analysis (CMA) is used for identifying the modes which are contributing to the coupling. As a result of this analysis, an X-shaped isolating block placed at the center of the cavity is proposed for increasing the isolation between ports. A wide-band four-port antenna with unidirectional radiation patterns is obtained with a measured impedance bandwidth (S 11 <-10 dB) ranging from 1.55 to 6 GHz (118%), covering most of the sub-6 GHz 5G bands. The proposed antenna provides four independent radiation patterns, with 16 dB of measured minimum isolation between ports and an efficiency higher than 84%. Multiple-input multiple-output (MIMO) compatibility is confirmed with a 4×4 MIMO simulated system with an envelope correlation coefficient (ECC)<0.5 in different propagation conditions. The antenna is easy to fabricate and presents a compact size of 129.5×129.5×28.2 mm 3 (0.68λ×0.68λ×0.15λ, at a frequency f=f min =1.55 GHz). Moreover, the antenna has the advantage of avoiding complex feeding structures with baluns or directional couplers.
