Design and Analysis of Monopole Antenna with Band pass Filters

A monopole antenna consists of single pole placed over a ground plane. This antenna is used to radiate or receive electromagnetic waves in all directions to the pole. A monopole antenna is used in various applications like broadcasting, communication etc. The proposed antenna consists of a monopole antenna with two band pass filters united into the feed line. Open loop filter and hair pin coupled filter are designed to improve the antenna's performance by rejecting unwanted frequencies. The antenna is simulated in Ansys HFSS. The simulation results show that the antenna has wide operating band width with high gain. So, the proposed antenna is suitable for applications such as wireless communication systems, UWB, WLAN applications etc..
