This paper presents a five‐element antennas system formed by integrating one sensing and four reconfigurable communicating antennas on a single substrate for cognitive radio applications in the 2.4 and 5 GHz WLAN bands. The five antennas are termed as A‐1, A‐2, A‐3, A‐4, and A‐5, where A‐1 is designed to sense in the 2.4 (2.4–2.484 GHz) and 5 GHz (...
This work presents a 12-element 360° azimuth plane scanning planar circular antenna array for compact THz wireless devices. Proposed array comprises of 12 bow-tie Yagi-Uda directional antennas, operating within 0.235–0.322 THz band where each antenna achieves a maximum radiation beam for an angle of around 30°, arranged in a circular fashion to cov...
A frequency reconfigurable 4-port integrated ultra-wideband and narrowband
antenna structure for cognitive radio application is reported in this article. The
proposed structure comprises four distinct antennas integrated on FR-4 sub-
strate of dimensions 42 42 1.6 mm. The first antenna, named as ANT-1, is
a CPW fed UWB antenna exhibiting 10 dB im...
