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.
