In this paper, a electrically beam scanning leaky-wave antenna (LWA) based on composite right/left-handed (CRLH) rectangular waveguide (RWG) is presented. In the proposed LWA, liquid crystal (LC) is chosen as tunable material, which could be controlled by applied electric and magnetic field. The beam of LWA proposed can be steered at a fixed frequency as the electromagnetic parameters of LC change...
A design method for miniaturized planar holographic antenna with surface-wave launcher feed is proposed. The antenna is fed by a printed surface-wave launcher(SWL) instead of a monopole or a horn, which leads to a complete planar antenna structure (operating between 23–26GHz). For the design example radiated at 30° off the normal. Two prototypes of miniaturized planar holographic antennas are designed...
