Dual frequency reconfigurable microstrip antenna using varactor diodes
2011
2011 XXXth URSI General Assembly and Scientific Symposium
Preserved Fulltext
A varactor controlled electronically reconfigurable dual frequency microstrip antenna is presented. Dual frequency operation is realized by embedding an X-slot in a rectangular patch. High tuning ranges of 26.3% and 15.3% are realized for the two resonant frequencies respectively, when the bias voltage is varied from 0 to 16V. This design has an added advantage of size reduction up to 77% and 64% for the two resonant frequencies compared to standard rectangular patch. A maximum band width of
