Low Profile Beam Steerable Antenna using PI Axis Posts for Massive-MIMO 5G Applications

5G networks promised to provide increased coverage, capacity and end-user throughput. Advanced antenna radiating system plays a very important role for the establishment of 5G networks. In this work, a novel low size profile enforced terminating boundary patch antenna array is proposed. This antenna array achieves a Hybrid beam steering with a low size through PI axis posts up to 33%. The antenna has a three-layer structure where a single layer PTFE composite based Rogers 5880 is utilized with a dimension of 15× 16 mm2. It operates at frequency band of 35 GHz with a wide bandwidth of 530 MHz and with a mean return loss of -28 dB. This radiating device is designed with the microstrip feed for the massive-MIMO 5G requirements.

Additive Manufacturing of Steerable Antenna Systems for 5G and Adaptive Cruise Control Applications

This chapter gives an insight view of the evolving additive manufacturing technology and its application for designing steerable front-end (FE) array antenna architecture dedicated to mmWave for the 5G network and the adaptive cruise control (ACC) applications. The manufacturing of RF system is a challenging work because it comes with complex designs, a long realization time, and high cost as well as weight. Technically, all these challenges could be addressed up with the use of additive manufacturing technology. It allows an increased flexibility in the manufacturing of complex designs such as steerable beamforming and other advanced RF products. Traditional machining technologies used to manufacture RF products are limited in their ability to produce complex shape. The AM technology allows to realize the entire designs in one single time-phase which positively impacts mass, cost, realization time, assembly quality and RF performance.
