A Low-Cost Partially Reflective Surface with Corner Reflector Antenna for Gain Enhancement

This paper presents a metallic partially reflective surface (PRS) integrated with modified corner reflector antenna for size reduction while maintaining high-gain radiation. The 15-degree reflector fed by blended monopole probe is designed at 9.0 GHz. To improve the gain of the proposed antenna, the metallic PRS is properly designed and mounted on the top of the proposed antenna. The unit cell of the PRS is made from purely copper sheet to support high power application. The reflection parameters of the PRS (reflection magnitude and reflection phase) are investigated and optimized by using CST Microwave Studio. The gain of the proposed antenna without and with the metallic PRS are 5.5 dBi and 16.1 dBi, respectively. The proposed antenna also offers other advantages, such as ease of design, and low fabrication and material cost.
