A height‐reduction antenna with simple structure for base station

Abstract

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).
