Abstract

The paper describes an antenna system for portable lightweight cognitive radios employing opportunistic spectrum access. Our approach comprises a frequency-agile narrowband antenna that is capable of sensing over a wide bandwidth and over different spatial directions within a miniaturized single-radio system assisted by parasitic antennas.

Keywords: Antenna arrays Broadband antennas Chromium Directive antennas Narrowband Sensors
