Abstract

Design of antenna for cognitive radio application is proposed in this paper. The design consists of two printed monopole antenna printed over FR4 substrate, sharing a common partial ground. The first antenna is the sensing antenna for spectrum sensing, having wideband characteristic and omnidirectional radiation pattern. The second one is the communicating antenna which is a frequency reconfigurable antenna with the existing switch on the antenna´s structure. The measurement shows that the reconfigurable communicating antenna is working at 2.35 GHz when the switch is OFF and it is working at 1.8 GHz when the switch is ON.
