Low-Profile Wideband Reconfigurable Plasma Antenna Design

Abstract

In this paper, a metric wave wideband reconfigurable plasma antenna is proposed. The wideband technique is based on traditional transmission branch line theory and reconfigurable property. The plasma antenna performs a wideband operation which is from 30MHz to 512MHz, and reflected coefficients are lower than −6dB. Radiation pattern is measured by UAV system with spectrum analyzer. Compared with traditional metric wave antenna, this structure has a lower profile and the total height is 0.5m. The shape is similar to folded dipole, it can be applied in vehicular and shipborne communicating systems.
