A novel optically controlled reconfigurable antenna for cognitive radio systems. In Proceedings of the IEEE antennas ... and implementation of an integrated UWB/reconfigurable-slot antenna for cognitive radio applications. IEEE Antennas and ... Frequency Reconfigurable Antennas Design for Cognitive ... Abstract. This paper proposes frequency reconfigurable antennas using genetic algorithm, suitable for cognitive radio applications. The optimization is applied to find the slot shape and the switches locations in the ground plane of monopole antennas for adjustment of the bandwidth.

Integrated Cognitive Radio Antenna Using Reconfigurable ... reconfigurable antenna for cognitive radio communication. In [1], the authors present a reconfigurable antenna based on photoconductive switches. An UWB antenna is also incorporated for channel sensing. A reconfigurable slot antenna for cognitive radio applications is presented in [2]. A New Reconfigurable Antenna Design for Cognitive Radio ... This letter presents a new antenna design suitable for cognitive radio communication. It consists of two structures incorporated together into the same substrate. The first structure is an ultrawideband (UWB) antenna covering the spectrum from 3.1-11 GHz for channel sensing. The second structure is a frequency reconfigurable triangular-shaped patch for establishing communication with another ... A Novel Optically Controlled Reconfigurable Antenna for ...

Reconfigurable Microstrip Printed Patch Antenna for Future ... Secondly, the varactor diode was exploited to verify this; by changing the bias voltage across the varactor from 0.21V to 12.9V, the antenna operates over the targeted range from 1500MHz to 2300MHz. Both the simulated and measured results show a stable performance. The proposed antenna may be suitable for future cognitive radio system. A compact UWB monopole patch antenna with reconfigurable ...
