TRANSMITTING/RECEIVING ANTENNA AND DESIGN METHOD OF SLIT

摘要

PROBLEM TO BE SOLVED: To provide a transmitting/receiving antenna of a structure easy to design.SOLUTION: A transmitting/receiving antenna includes: two reflectors; a back plate; an isolator; a plurality of transmission elements; a plurality of reception elements; and a radome. The two reflectors are conductive plates and are arranged opposite to each other. The back plate is a conductive flat plate and is in contact with both of the two reflectors. The isolator is a conductive flat plate, is arranged between the reflectors in the way that they face both of the reflectors, and is in linear contact with the back plate. The isolators also have slits for detouring radio waves from the plurality of transmission elements to a side of the plurality of reception elements. The plurality of transmission elements are arranged between one of the two reflectors and the isolator. The plurality of reception elements are arranged between the other of the two reflectors and the isolator.SELECTED DRAWING: Figure 2
