Evaluation of a transmit-array base station for mm-wave communications in the Fresnel region

A dual-polarized transmit-array is evaluated as an indoor base station antenna for mm-wave communications at 28 GHz. The antenna is designed to produce a constant field distribution in a specific area generating different spots wherein the devices are placed. The antenna is fed in a multi-feed configuration, radiating a different coverage area each feed. The design technique is based on a phase-only synthesis (POS) and a proper distribution of the feeds. The transmit-array is simulated and finally manufactured. The prototype is based on dielectric-only elements which provide a low-cost solution. The results show a high agreement with simulations. Moreover, the presented results validate the design technique as well as transmit-array antennas for this purpose.
