Wideband Monopole Antenna for WLAN Applications
Abstract — This paper presents a circular patch antenna for WLAN applications with wideband characteristics. It is shown that the impedance of the antenna is matched over wideband by using the partial ground plane and quarter wave transformer with slotted TX-Line. Ansoft HFSS is used as a simulation tool to map the numerical results for …
