Abstract

With the progress in wireless communications techniques in recent years, a new promising concept of wireless sensor networks has received a well deserved attention by researchers all over the world. Embedded sensors offer intelligent devices and systems that are able to react to events and physical conditions of the real world. The most important component in sensor is its TX/RX antenna. In this paper, UWB printed monopole antenna with embedded reconfigurable multi band frequency rejection notches is proposed. Frequency notch is achieved by using a ground-plane slot (GPS) and lumped capacitors. Reconfigurabiltiy is introduced in a way you can independently switch ON/OFF the band notches by mean of RF switches. Simulation results are verified with measurements.
