Planar antenna system for mobile radio applications, has coaxial waveguide whose inner and outer conductors make predetermined angle with axis of slit structure of conductive disk

摘要

A pair of conductive disks have segmented slit structure for arranging capacitive load elements. A coaxial waveguide is arranged such that the inner and outer conductors (3.1,3.3) make an angle of 90/!20 deg with axis of slit structure.
