Portable radio antenna performance in the 150, 450, 800, and 900 MHz bands 'outside' and in-vehicle

Abstract

Portable radio antenna performance on the human body was measured for several different radio models in the 150, 450, 800, and 900 MHz. bands. In-vehicle measurements were made at an outdoor antenna range equipped with a vehicle turntable. All other measurements were made in an anechoic chamber. Tests were made at the head level, at the side-level swivel-type carry case, at the side-level belt-loop type carry case, and at the shoulder level with a speaker microphone antenna. A statistical analysis was made of the data for use in coverage propagation predictions, and system designs. The results of the statistical analysis are presented.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
