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 (...
