摘要：
A circularly polarized(CP) antenna array with the capability of beam-scanning based on liquid crystal(LC) is proposed. TUD-649 LC is adopted to realize beam steering by controlling the permittivity of LC. Circular polarization is obtained using two orthogonal slots. The radiation array is fed by four-port power dividers. The peak gain of the antenna is 10.5 dBi. The scanning angles from -20 degrees to 20 degrees are achieved at 12.6GHz.
