摘要：

This article presents a new reconfigurable modified Vivaldi antenna with improved gain. A simple Vivaldi antenna is modified by adding slots in the extremities to demonstrate good radiation characteristics. The antenna reconfiguration is attended by inserting diodes PIN switches at specific localizations in the aperture antenna to change its resonance frequency. A wide bandwidth from 2 to 5 GHz and several narrow bands are obtained. This antenna is a good candidate for multi-applications necessitating frequency reconfigurable antenna.
