Abstract
Number of frequency bands that have to be covered by smart phones, are ever increasing. This broadband coverage can be obtained either by using a low-Q antenna or a high-Q tunable antenna. This study investigates high-Q antennas performance when placed in proximity of the user. This study is carried out through measurements, using Cellular Telecommunications Industry Association (CTIA) specified head and hand phantoms. The results of the high-Q antenna are, at low as well as high frequencies, compared to the results for a low-Q antenna. The results show that detuning of low-Q antennas is more severe compared to high-Q antennas. However, the drop in efficiency is comparable for both antennas in proximity of the user.
