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° 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.
