Multiband Reconfigurable Antenna for Cognitive-Radio

A Selective Frequency-Reconfigurable Antenna for Cognitive … Mar 11, 2014 · Abstract: This letter presents a selective frequency-reconfigurable antenna, suitable for cognitive radio applications. The proposed antenna is capable of switching between a wide operating band of 2.63-3.7 GHz and four different subbands, which allows using it for sensing the entire band and then adjusting its bandwidth to select the suitable sub-band and prefilter out the other ones. 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 Antennas Design for Cognitive Radio … Oct 28, 2017 · 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.

A Frequency Agile Semicircular Slot Antenna For Cognitive Radio ...

In this paper, a reconfigurable multi band notches antenna, for cognitive radio applications, is proposed. The antenna can be operated as ultra wideband, and is reconfigurable in terms of the ability to select one or two notches band in the SRR resonant frequency. Towards software defined antenna for cognitive radio networks ... The rest of this paper is organized as follows: Section 2 shows the related work about flexible reconfigurable antenna array and RF-switches technologies. Section 3 presents the design and fabrication of the proposed antenna. Section 4 introduces the cognitive radio model and performance metrics to compare between the different types of RF ...
