Abstract

A broadband unidirectional CPW-fed rectangular slot millimeter wave antenna based on MEMS (Micro-Electro-Mechanical Systems) micro-fabrication technology was discussed. A wide impedance bandwidth of 80% with VSWR≤2 is achieved. By adding several cut-off slots and a guiding slot, the antenna radiates unidirectional, and the max gain of the antenna rises from 3.8 dB to 6.8 dB. Ansoft HFSS and CST microwave studio, two high frequency structure simulation software based on finite element method (FEM) and finite integration method (FIM), were used to analyze the antenna performances.
