摘要

In this paper, we introduce a dual-, wide-band dual-polarized dielectric resonator antenna (DRA) with high isolation and low cross-polarization. The proposed antenna has realized dual-polarize by applying slot and balanced strip feed, which achieved high port isolation of -52 dB and low cross-polarization in operating band. The fundamental mode TE_(111) and higher order mode TE_(113) have been excited for dual-band application. TE_(112+δ) (δ<1) mode, a new kind of mode never be mentioned, and strip mode are merged with previous modes for wideband application, which achieved 23.9% (1.73-2.20 GHz), 6.1% (2.53-2.69 GHz) at lower and upper band, respectively, for port 1 and 12.4% (1.81-2.05 GHz) 16.4% (2.35-2.77 GHz) for port 2. The S-parameters, symmetric radiation pattern, antenna gains of the designs are studied. It's suitable for this application of base station antenna.

S参数,对称辐射模式,设计的天线增益研究过。它适用于此应用基站天线。
