摘要： A novel design of dual-band reconfigurable slot antenna is proposed in the paper. The configuration of the proposed antenna is based on a folded slot with a branch edge formed by multiple strips loaded with circuit components. In the design, the antenna is decomposed into networks, and the corresponding equivalent circuits are deduced. By applying resonant condition on the equivalent circuit at the desired center frequencies, the circuit components can be determined. The proposed design is later transformed into a reconfigurable antenna by using varactors. The antenna configuration is also modified for applying biasing voltages to varactors. Dual-band reconfigurable operation of antenna is studied and demonstrated for S-band applications at 2.45 GHz and GPS at 1.227/1.381/1.575 GHz. The design approach is described in details. Also, antenna measurements are conducted for design validation. 其他題名： TAP 出版者： IEEE 出版日期： 2015-02 出處： IEEE transactions on antennas and propagation, 2015-02, Vol.63 (2), p.508-516 資源來源： IEEE Electronic Library (IEL) 識別號： ISSN: 0018-926X 識別號： EISSN: 1558-2221 識別號： DOI: 10.1109/TAP.2014.2382121 識別號： CODEN: IETPAK
