Abstract

This paper presents an ultra-wideband (UWB) antenna which has low cost, a compact size, and can achieve electronically beam steering across a range from 0° to 360° and adaptive beamforming. To reduce the size and cost, the antenna employs the configuration of electronically steerable parasitic array radiator (ESPAR). The parasitic elements consist of twelve folded monopole antennas which are placed surrounding a thick rod monopole antenna. The thick rod monopole antenna serves at the driven element. Each folded monopole is loaded with a PIN diode, and by controlling the DC voltages applied to the PIN diodes, the antenna can achieve electronically beam steering and adaptive beamforming. To prove the concept, a prototype at S band is developed and the antenna is shown to be able to operate over the frequency band from 2.0 to 3.1 GHz while the height of the antenna has been reduced to 15% of the wavelength at 2.0 GHz. The antenna is promising for UWB communications and radar applications.
