DESCRIPTION:Multifunctional Filtering Antennas\n\nJawad Y. Siddiqui\n\nUniv
 ersity of Calcutta\, Queen&#39;s University and Royal Military College of Cana
 da\n\nSummary:\n\nModern RF systems often require multiple antennas to sup
 port various frequency bands. Reconfigurable antennas address this need by
  providing frequency agility\, compact size\, and reduced hardware complex
 ity. The proposed antenna achieves this through electrical reconfiguration
  enabled by the embedded SRRs and PIN diodes.\n\nThe techniques proposed i
 n this work have been implemented on two types of UWB antennas\, a printed
  monopole antenna and a printed antipodal tapered slot antenna (ATSA) to v
 alidate the concept on radiators with distinct radiation characteristics: 
 omnidirectional and directional\, respectively. In both cases\, split ring
  resonators (SRRs)\, magnetically coupled to the CPW feed line\, function 
 as band-stop filters\, introducing a frequency notch in the UWB response a
 round their resonance. When a set of PIN diodes embedded in the feed line 
 are forward biased (ON)\, the antenna transforms into a narrowband band-pa
 ss filter centered at the same resonance frequency\, thereby realizing com
 plementary frequency responses from a single antenna structure.\n\nA key f
 eature of the design is that it preserves the original radiator geometry. 
 The work demonstrates a compact\, versatile\, and effective approach to ac
 hieving multifunctionality in UWB antennas. The integration of reconfigura
 ble filtering into the feedline enables real-time switching between wideba
 nd and narrowband operation\, making the design especially suitable for co
 gnitive radio\, multi-standard wireless systems\, and MIMO applications.\n
