Reconfigurable slot antenna for cognitive radio applications

cognitive radio applications. A reconfigurable slot antenna for cognitive radio applications is presented in [4]. The antenna can be switched between any one of three discrete states. In [5], it is shown that once a cognitive design manages to learn the RF environment, one can use the collected data to train A compact UWB monopole patch antenna with reconfigurable ... The UWB antenna is designed on an FR4 substrate with a thickness of 1.6 mm. The relative permittivity of the substrate is Ɛ r = 4.4 and loss tangent is 0.02. The basic configuration of the antenna consists of an elliptical radiating patch with a slot loaded partial rectangular ground plane.

Frequency Reconfigurable Microstrip Antenna for Cognitive ... reconfigurable antenna, suitable for cognitive radio applications. Reconfigurability is achieved by inserting PIN diode switches in DMS(defected microstrip structure) ‘T’ slot filter. The proposed Reconfigurable Antennas for UWB Cognitive Radio ... In this chapter, reconfigurable antennas are reviewed for ultra-wideband (UWB) cognitive radio communication applications. The defected microstrip structure (DMS) has been reviewed and integrated into the UWB antennas to form the desired filtering antennas which can filter out unexpected narrowband signal interferences. Then, switches are incorporated into the filtering UWB antennas to ... Frequency Reconfigurable Microstrip Antenna for Cognitive ...

Design of Reconfigurable Band Notches Antenna for ... In this paper, an antenna with reconfigurable band notches, for cognitive radio applications, is proposed. The antenna can be operated as ultra wideband, and is reconfigurable in terms of the ability to select a notched band in the SRR resonant frequency. The reconfigurable band notches are induced using a band-stop filter based on split-ring resonators (SRRs), and are controlled using ...
