Abstract
A stacked multilayer circular patch antenna with wide bandwidth has been realized on a fourteen layer multilayer microwave board for the first time. The main radiator consists of eight layer disk plates, and the antenna is fed by a conductor-backed coplanar waveguide (CBCPW). The measured results show that the multilayer antenna can operate within 2.8GHz-5.8GHz and have a relative bandwidth of 70%. The antenna has potential application for wireless communications
