A wideband dual‐polarized planar antenna with triple radiators is proposed for the LTE600/LTE700/GSM850/GSM900 base station in this paper. A novel concept of multi‐radiator for multi‐resonance by close coupling feed is presented and analysed . The proposed antenna is mainly composed of two pairs of loop dipole, L‐shaped radiator, step dipole, two L‐shaped feed lines, balun and reflector. The reflector is designed with a centrosymmetric partible baffle for directional radiations, which contribute to stable radiations as well. Owing to the novel closely coupling scheme for multi‐radiators, three resonances are simultaneously excited within the desired band, producing a wide bandwidth of 47.7% (from 0.59 to 0.96 GHz) for |S11| < −15 dB with high isolation more than 30 dB. Moreover, an average gain of 8.8 dBi as well as stable radiation patterns are achieved simultaneously.

A compact wideband dual-polarized antenna for base station application is proposed. The antenna element consists of a main radiator, two baluns, and a reflector. Two methods are used to enhance bandwidth and improve the port-to-port isolation. Firstly, by integrating the parasitic elements to traditional dipoles, new resonant modes are introduced to realize broadband, which can be controlled flexibly. Subsequently, part of the parasitic elements is removed to form asymmetric dipoles. Due to the asymmetry construction of the design, the polarization isolation of the antenna achieves more than 30 dB in the whole working band with stable radiation patterns. In addition, the specially designed parasitic elements achieve enhanced bandwidth without increasing the size of the radiator. The Simulation and measurement results show that the antenna has an impedance bandwidth of 32.7% (690-960 MHz). Moreover, a stable half-power beamwidth (HPBW) of 68°±5°and a high gain of 8.5±0.3 dBi is achieved. To verify the performance of the antenna, a compact high-gain base station array was designed and manufactured. The good performance of the proposed antenna makes it a promising candidate for 4G/5G base station application.

“…In order to obtain directional radiation and high gain, base station antennas generally use a perfect electrical conductor (PEC) as the reflector, and at the same time to improve the radiation efficiency of the antenna, the height of the antenna from the reflector is usually 0.25λ 0 . [1][2][3][4][5][6][7][8] Therefore, low-profile antennas have important research for minimizing the manufacturing charge of operators and improving the antenna's anti-risk capability.…”

In this article, a height-reduction dual-polarized antenna suitable for base station applications with a simple structure is proposed. By adopting the form of bilateral coupling feed, the height of the antenna has been significantly reduced. The working mechanism of height-reduction of the antenna is given. The experimental resultsshow that the antenna operates at 0.698-0.96 GHz for reflection coefficient <À12 dB with isolation (ISO) of more than 30 dB. It has a stable gain of 8.4 ± 0.6 dBi and a half-power beamwidth (HPBW) of 66.8 ± 6.8 in the working band, and the height of the proposed antenna is only 0.115λ 0 , which is much smaller than the traditional 0.25λ 0 (λ 0 denotes the free wavelength corresponding to the center frequency).
