Abstract
A small size broadband microstrip patch antenna with small ground plane has been fabricated using MEMS. Multiple layer substrates we used to realize small size and broadband characteristics. The microstrip patch is divided into 4 pieces and each patch is connected to each other using a metal microstrip line. The fabrication please process is simple and only one mask is needed. Two types of microtrip antennas are fabrication Type A is the microstrip antenna with metal lines and type B is the microstrip antenna without metal lines. The size of proposed microstip antenna is $8{\times}12{\times}2mm^3$ and the experimental results show that the antenna type A and type B have the bandwidth of 420MHz at 5.3 GHz and 480MHz at 5.66 GHz, respectively
