Title:
FREQUENCY SHARING ANTENNA
Document Type and Number:
Japanese Patent JPS6018004
Kind Code:
A
Abstract:
PURPOSE: To obtain the equivalent efficiency among antennas with use of each exclusive primary antenna by piercing a horn antenna through the area at the center of a print antenna where no radiating element is formed.
CONSTITUTION: For higher frequencies, a primary reflector 1 is irradiated by a horn 9 for high frequencies which is piercing through a hole drilled at the center part of a print antenna 13 where no irradiating element 16 is formed. Then the reflector 1 reflects two radio waves of high and low frequencies radiated from the antenna 13 to the spaces along radio wave routes 7 and 7' respectively.
