Frequency-Reconfigurable Archimedean Spiral Antenna
IEEE Antennas and Wireless Propagation Letters, 2013In this letter, a frequency-reconfigurable Archimedean spiral antenna is presented. The proposed antenna consists of a two-arm spiral fed by a coplanar waveguide (CPW) feeding line. A pair of meandered slotlines is implemented at both sides of the CPW-fed slot on the spiral antenna to introduce frequency reconfiguration.

Frequency reconfigurable metamaterial resonant antenna
2009 Asia Pacific Microwave Conference, 2009In this paper, a frequency reconfigurable metamaterial resonant antenna is presented. In order to realize the proposed antenna, a mushroom structure-based zeroth order resonant (ZOR) antenna is used. The left-handed mode of the ZOR is utilized to realize small antenna.

Miniaturized frequency reconfigurable slot antenna
2015 Asia-Pacific Microwave Conference (APMC), 2015A frequency reconfigurable slot antenna is proposed. By inserting three p-i-n diodes inside a U-shaped short slot and two L-shaped open slots, which are etched in the ground plane, the antenna can achieve four states: 2.3/5.8 GHz in two single band modes; 2.3/4.4GHz and 4.4/5.8GHz in two dual band modes. The antenna has a size of 25 mm × 27 mm (0.31 λ1

Frequency reconfigurable microstrip patch antenna
2012 IEEE Asia-Pacific Conference on Applied Electromagnetics (APACE), 2012A frequency reconfigurable microstrip patch antenna is proposed. Three switches are used to produce six reconfigurable frequencies. Those switches are positioned in the slot places underneath the patch. A reflector is placed behind the antenna. It was found that, at all frequencies, directional radiation patterns are obtained.
