Microstrip line antenna with crank-shaped elements and resonant waveguide elements |
摘要 |
A microstrip line antenna generally used for receiving an electric wave from an artificial satellite, which comprises a plane dielectric substrate and a plurality of crank-shaped microstrip lines arranged on the substrate. The improvement comprises a number of half wavelength waveguide elements arranged on a plane lying parallel to the substrate in front of the microstrip lines at a predetermined distance therefrom for improving the signal-to-noise ratio of the antenna and reducing the number of antenna elements.
