Abstract
With the future LTE auction for TV white spaces
at 600 MHz, there is a strong need for efficient handset antennas
operating at very low frequencies. This paper shows a tunable
antenna covering the LTE bands from 600 MHz to 2.6 GHz.
The antenna uses state-of-the-art MEMS tunable capacitors in
order to reconfigure its operating frequency. In this work, the
design mitigates the tuning loss with a tunable extended ground
plane. The resulting dual-resonant antenna exhibits a peak total
efficiency of -3.9 dB at 600 MHz.
