Summary:
As highly efficient and low cost planar antennas in millimeter- or quasi-millimeter-wave bands, dielectric leaky-wave antennas (DLWA) have been developed [1],[2] which consists of dielectric substrates periodically loaded by parallel metallic strips. One of the key technologies for DLWAs is a feed that launches a dominant surface-wave mode into the substrate slab. We have developed several types of the feeds so far [2]-[4]. Recently we proposed a new feed using a parallel-plate waveguide excited coupling slots which provides high antenna efficiency and good compatibility with a planar RF integrated circuit, and clarified its feasibility by computer simulation [5 ]. In this paper, we will describe experimental results of two types of 24 GHz high gain DLWA having the proposed feed.
