摘要: Cognitive radios seem to provide an answer the problem aroused from continuously increasing wireless applications that result in congestion of spectrum and increase interference. require agile components therefore antennas with reconfigurable characteristics. The current paper presents three use PIN diodes achieve frequency, pattern polarization reconfigurability respectively. An annular slot microstrip-fed antenna (ASA) is matched at different frequencies matching network results a operation frequency. same radiator used radiation by integrating two on circumference. Lastly circular patch presented which appropriate it can switch between left hand (LHCP) right (RHCP).
