“…Patch antenna is popular with low profile, potential low cost, conformal nature, and ease of mass construction, but the use of patch antenna is limited because of its narrow bandwidth. The bandwidths of [1] and [2] are only 26% and 37% for return loss higher than 10 dB, respectively. Similar to patch antenna, wideband and dual-polarized characteristics can also be achieved with slot antenna.…”

“…A number of broadband dual-polarized antennas have been developed for base stations. The conventional choices mainly include patch antenna [1][2][3], slot antenna [4][5][6] and cross-dipole antenna [7][8][9][10]. Patch antenna is popular with low profile, potential low cost, conformal nature, and ease of mass construction, but the use of patch antenna is limited because of its narrow bandwidth.…”

Abstract-A novel wideband dual-polarized antenna is presented for 2G/3G/LTE base-station applications. The proposed antenna consists of two orthogonal modified bowtie dipoles, parasitic elements and a cavity. By using parasitic elements and compact cavity, the antenna achieves a wide impedance bandwidth about 77.3% (VSWR < 1.5) for both ports. Both simulated and measured results show that the proposed antenna has a port isolation higher than 31 dB and high gain (> 8.5 dBi) over the entire operating band. Moreover, good cross-polarization (> 25 dB) performance and a front-to-back ratio better than 20 dB are also verified by measured results.

“…The overlapped fractional bandwidth is improved to 11.5%. In [2][3][4][5], feeding methods such as meandering/T-type probe, aperture coupling and probe & aperture hybrid feeds are proposed to excite patch antennas for a wide bandwidth up to 26%. However, it is still far from enough to cover PCS, UMTS and WLAN applications at the same time.…”

Abstract-A low-profile, wideband dual-polarized antenna with unidirectional radiation patterns is the design goal of this paper. To obtain such antenna characteristics, the design is divided into two steps. First, a coax-feed wideband antenna element with a simple geometry is proposed. The antenna element consists mainly of a quasi-square patch-dipole, a coupling E-shaped feeding structure and a shorting pin. The electromagnetic coupling between the feeding structure and the non-contact quasisquare patch can be flexibly controlled by a pair of fan-shaped stubs. Secondly, two pairs of the proposed antenna elements are selected to construct a dual-polarized antenna. To further reduce the profile of the antenna, two techniques are utilized. One is the mutual coupling distributing among the elements while the other is to add four rectangular stubs within the inner region. A prototype of the dual-polarized antenna is fabricated and measured. Measurement results demonstrate that the prototype antenna obtains an overlapped fractional bandwidth of 38.9% from 1.7 to 2.52 GHz with a good isolation higher than 32 dB. Both unidirectional radiation patterns with front-to-back ratios better than 20 dB across the whole frequency band and cross polarization levels lower than −22 dB in most operating frequency band are obtained. Additionally, the dual-polarized antenna achieves average gains about 9.9 dBi and 10.1 dBi for Port 1 and Port 2, respectively.

“…By embedding a U-slot or V-slot in a suspended rectangular patch [10][11][12], good impedance matching over a wideband can be obtained. M-shaped meandering probe was used to feed the patch antenna in [13] to increase the bandwidth. However, all these proposed antennas have high cross-polarization levels.…”

Abstract-A wide bandwidth folded V-shaped patch antenna with high gain and low cross polarization is presented. The proposed antenna is composed of a folded V-shaped patch, an H-shaped coupling slot cut in the ground plane and a feed line with a stub printed on the bottom layer of the grounded substrate. By folding the V-shaped metallic patch, the proposed antenna can achieve a low profile structure and good performance in radiation patterns. The antenna element and the antenna array operating at 2 GHz were fabricated and tested. The prototypes with the single element can achieve a −10 dB return loss bandwidth of 28.5% (1.65 to 2.2 GHz) and a stable gain of 8.6 dBi, while the 1 × 2 array exhibits a bandwidth of 34.1% (1.58 to 2.23 GHz) and a stable gain of 11.5 dBi.
