A steerable linearly-polarized antenna design based upon a novel variable signal splitter

This paper presents the design of a linearly-polarized antenna with extended steerable angle of orientation. Polarization agility is attained by the adoption of a novel 0°/180° variable power splitter and a dual-fed antenna. The proposed circuit features simple structure with minimal number of RF components, single voltage operation and zero dc power consumption. For experimental demonstration, the measured results of a 1.4 GHz antenna implemented on microstrip are shown.
