Investigation of user effects on mobile phased antenna array from 5 to 6 GHz
12th European Conference on Antennas and Propagation (EuCAP 2018), 2018•ieeexplore.ieee.org
The goal of this paper is to evaluate the impact of the user to the performance of a phased
antenna array in the frequency range from 5 to 6 GHz. The design consists of four quarter
wavelength dipoles printed on the short edge of an FR4 substrate. Simulations including a
105° phase shifter proved that the antenna array can cover a 120° beamwidth, with a gain of
7 dBi. The analysis of the user effects in terms of total scan pattern (TSP) and coverage
efficiency is carried out via simulations both in data mode and in talk mode. The comparison …

The goal of this paper is to evaluate the impact of the user to the performance of a phased antenna array in the frequency range from 5 to 6 GHz. The design consists of four quarter wavelength dipoles printed on the short edge of an FR4 substrate. Simulations including a 105° phase shifter proved that the antenna array can cover a 120° beamwidth, with a gain of 7 dBi. The analysis of the user effects in terms of total scan pattern (TSP) and coverage efficiency is carried out via simulations both in data mode and in talk mode. The comparison with the performance in free space shows a loss in gain from 2 dB up to 7 dB, due to the user hand and the user hand-head respectively. Simulation results have been confirmed by the measurements of the prototype with a hand and head phantoms.
