Design of Reconfigurable Notch Band Antenna for UWB Application using P-I-N Diodes

Abstract- The advantage of the antenna with reconfigurable band notch is to ably make use of the frequency spectrum resources and work collectively well along with the presented narrowband wireless services. In this article a compact design and analysis of reconfigurable triple notch band antenna using DGS for UWB applications is proposed. The basic design has main feature to reduce interference from narrow band applications after that design has ability to recall notch bands according to different states of switches placed on defected ground plane. The presented design consist of microstrip feed line reconfigurable antenna having size of 16 ×12.4 mm2. Keywords: DGS, Microstrip, Gain, Reconfigurable antenna, P-I-N diode
