Abstract
A new center-fed circular patch antenna with two coupled annular rings is presented. When the two annular rings are coupled properly, a wide band from 5.45GHz to 7.16GHz is achieved with a monopole-like radiation pattern. Measured results show that the antenna with a low profile of 0.027 wavelengths (at 5.45GHz) has a bandwidth of 27.1% and ameasuredmaximumgain of 6 dBi. The radiation pattern is omnidirectional and remains relatively stable within the operating band. Copyright © 2014 Authors.
