Abstract
In this paper, a varactor-tuned filter-antenna (filtenna), for cognitive radio applications is proposed. The presented technique is based on electronically tuning the resonant frequency of a compact tunable band-pass filter, which is integrated into a wideband antenna. The change in the loading capacitance of the installed varactor results in frequency tuning of the whole filtenna system, while preserving its radiation characteristics.
