Abstract
An integrated radiating and coupling device (30) for a duplex communication radio (26) is formed using a ferrite body (36) having first and second surfaces. A multi-port circulator (40) is mounted on the first surface. The circulator (40) has at least three ports; a transmitter port (42), a receiver port (44), and an antenna port (38). A patch antenna (32) is mounted on the second surface and connected to the antenna port (38) by, for example, a wire passing through a via hole in the ferrite body (36). The device (30) provides transmitter and receiver isolation, antenna coupling, and filtering in a single integrated structure.
