Design of broadband microstrip patch antenna for FDD-LTE/WCDMA
摘要
Abstract
A T-shaped microstrip patch antenna which was fed by coaxial line was proposed. The antenna can realize the function of wide bandwidth by changing the rectangular patch surface current path. At the same time, a new type of feed structure was introduced and a vertical feed plate was used to form a linear feed to improve the impedance matching characteristics of the antenna. The antenna was simulated, and the structure parameters of the antenna were obtained by analyzing the influence of slot shape and length on the radiation characteristics of the antenna. The simulation results show that the frequency channels of the antenna are within 1.7-2.3 GHz when S11≤-10 dB, and the relative bandwidth of the antenna is 30%. Moreover, it has good unitary radiation. The peak gain of 1×2 antenna array is 12.6 dBi, which could be applied to the mobile communication base station of FDD-LTE and WCDMA.关键词
