Title:
TRANSMISSION OR RECEPTION SYSTEM WITH WAVEGUIDE ANTENNA OUTPUT AND SUCH ANTENNA OUTPUT
Document Type and Number:
Japanese Patent JPS6059801
Kind Code:
A
Abstract:
Antenna output for a planar antenna comprising an array of receiving elements provided by two networks (20, 30) of high frequency transmission lines and three sheets (10, 40, 50). The first sheet (10) comprises first cavities (11), the first and second transmission line networks are planar, located respectively on either side of this first sheet and, for signal reception, coupled to each of the cavities by a corresponding number of distinct ends forming exciting probes along two perpendicular axes. The third and second sheets (40, 50) are located on the other side of both of these networks and comprise second and third cavities (41, 51) which are in line with the first cavities. The third cavities are short-circuited in a plane parallel to the surfaces of the sheets, and these sheets are made of a metal or of a dielectric material having metal-plated walls of the cavities. The antenna output is formed by ends (122, 132) of the two transmission line networks which form exciting probes coupled to a waveguide (60) which is located in and opens toward the rear of the antenna.
