Title:
PARALLEL BOARD WAVEGUIDE ANTENNA
Document Type and Number:
Japanese Patent JPS5990406
Kind Code:
A
Abstract:
A parallel plate waveguide microwave antenna is presented in which transmission or reception of microwave energy is effected by radiating waveguide slots or apertures in a metallized glass plate or plate of other rigid dielectric material. The metallized glass plate cooperates with another metallized glass plate or other rigid dielectric material or a metal plate to define a parallel plate waveguide with air or an inert gas or vacuum as the dielectric between the plates. When used as a transmitter antenna, a central electrode propagates waves in the dielectric medium in expanding circles; and the slots or apertures in the metal layer act as scattering sites to couple the waves to free space. When used as a receiver antenna, the reverse will occur.
