Abstract
With the continuous development of the wireless communication, a device needs to integrate multiple antennas, which will lead to increased volume, increased cost, electromagnetic compatibility problems and increased weight. This paper presents a [Formula: see text] reconfigurable antenna array based on RF MEMS switches. The modeling script of [Formula: see text] reconfigurable antenna array is written in MATLAB by using MATLAB-HFSS-API. In order to quickly get a switch array with target frequency, genetic algorithm is applied to [Formula: see text] reconfigurable antenna array. Taking the [Formula: see text] reconfigurable antenna array as an example, a switch array with the resonant frequency of 3.81 GHz is searched from its 4096 switch arrays. The switch array found by genetic algorithm is 1 1 0 0 1 0 0 1 1 0 1 0. The resonant frequency and S11 parameter of this switch array is 3.81 GHz and −20.96 dB. The search takes 6.77 h and the efficiency is 17 times of the simulating all switch arrays.
