A High-Gain Circularly-Polarized Holographic Antenna Based on Impedance-Modulated Surface
A high-gain circularly polarized (CP) holographic antenna (HA) based on impedance-modulated surface (IMS) is proposed in this paper, which is composed of a source antenna and the IMS. A monopole antenna working around 11.4 GHz can drive the IMS. Surface wave generated by the monopole can be converted into directional CP wave through the IMS. The radiation characteristics of the three kinds of phase modulated HAs are compared and 12-phase modulated HA is selected as the proposed antenna at last. The peak gain of the presented CP HA is up to 18.7 dBi at 11.4 GHz. The operating band of the CP HA is from 10.5 to 13.5 GHz (25%). In addition, a good agreement is achieved between simulation and measurement. Moreover, the proposed antenna has the advantages of simple production process and low cost.
