Abstract

An antenna with reconfigurable bandwidth is conceived and presented. It is a slot antenna that maintains its resonant frequency, and has two modes of operation, a wideband and a narrowband mode. The modes are activated by the state of the vanadium dioxide thin film that acts as a switch and varies the size of two metallic islands on the antenna aperture. The antenna was designed, simulated, and fabricated. The measurements validated the simulated results. Such antennas can find uses in weak signal applications, while this particular configuration is not easily achievable using traditional off-the-shelf components such as PIN diodes, MEMS or FET transistors.
