Dual-Port Endfire Millimeter Wave Reconfigurable Antenna with Optimized Pixel Surface

A dual-port 1×2 antenna array incorporating a parasitic pixel surface in front of the array is proposed. By optimizing the pixel surface, different radiation patterns can be provided by each port. To demonstrate the effectiveness of the approach, a dual-port design, with patterns directed to 112° and 66° and gains of 7.87 dBi and 6.95 dBi respectively at 28 GHz, is provided. A feature of the design is that no RF switches are needed in the pixel surface. The proposed antenna array can be suitable for future fifth-generation (5G) wireless communication systems.
