Dual-Band Omnidirectional Circularly Polarized Antenna
IEEE Transactions on Antennas and Propagation, 2013 A dual-band omnidirectional circularly polarized antenna is proposed. The antenna comprises back-to-back microstrip patches fed by a coplanar waveguide. A very low frequency ratio of 1.182 has been achieved, which can be easily tuned by adjusting four lumped capacitors incorporated into the antenna.

Dual-band switched beam array fed by dual-band Butler matrix
Electronics Letters, 2011 A two layer dual-band switched beam system operating at two separate frequency bands is proposed. This system consists of a dual-band 4×4 Butler matrix at the bottom layer and a dual-band microstrip antenna array at the top layer. The antenna array is fed by a Butler matrix to produce four beams that can be tilted in different four directions.
