Prototype specification of antenna and radio front-end schemes for PAN devices

This document provides antenna system specifications for the MAGNET Beyond prototype.

Requirements on selecting antenna elements and diversity antenna systems are presented. A number of antenna elements and diversity systems suitable for MAGNET systems are specified. Presented antennas can be implemented in the prototype directly, or used as references in antenna selections for the prototype.

Interference mitigation on antenna system level for both HDR and LDR systems is investigated.

For the LDR system, interference from the HDR system and UWB systems is identified as most critical. Front-end filtering with high attenuation on 5.2 GHz is suggested to suppress interference from the HDR system. A low-complexity switching diversity antenna system is designed to mitigate UWB interference. The performance of proposed scheme is evaluated with measured channels. The implementation of the scheme is studied with the LDR simulation chain.

For the HDR system, an antenna switching diversity scheme is evaluated with measured channels. The potential diversity gains both in increasing received power levels and mitigating interference are investigated.
