A circularly polarized curved surface array antenna with high gain
2012
A circularly polarized curved surface array antenna with high gain is presented. The array, which can perform circular polarization operation, is constructed on a cured plane. The measured 10dB return loss (RL) bandwidth is 15 % (5.25 to 6.1 GHz), and the measured 3dB AR bandwidth is 53% (5.4 to 8.4 GHz). Not only does the proposed antenna feature broadband operation, but it also possesses high-gain characteristic. The antenna gain is significantly enhanced to 20 dBic by the introducing of the multiple array.
