Abstract

This paper investigates the impact of a left-handed grip on the coverage of a handset featuring three antenna arrays operating in the n257 frequency band of 26.5 GHz - 29.5 GHz. Beam steering is implemented using multi-bit phase shifters while the handset is held with a left-handed grip. Results are comparedto a right-handed grip, and a handset in free space. For a lefthanded grip, beam steering increased the coverage region (in which gain is greater than 0 dBi) from 23.8% to 57.7% through the use of 3-bit phase shifters. Similarly, coverage increased from 24.7% to 61.0% for a right-handed grip. This paper also investigates the benefit of increasing the number of bits available to the multi-bit phase shifters and results show performance improvement begins to plateau around 3 bits. From the data collected in this paper, a right-handed grip provides better coverage than a left-handed grip for the simulated scenario.
