Miniaturized Planar Holographic Antenna with Surface-Wave Launcher Feed

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 degrees off the normal. Two prototypes of miniaturized planar holographic antennas are designed by simply cutting out the inefficient region. The first demonstrates that the area of the miniaturized is 48% smaller and the gain is 0.7dB in simulation higher than that of the original antenna. Similarly, the second achieves that the area of the miniaturized is 72% smaller and the gain is 0.3dB in simulation higher than that of the original antenna.
