Abstract: A mounting base (14) is fixed to an antenna (13) or an antenna bracket (15) for supporting the antenna (13). A baseband unit (11) and an RF unit (12) are fixed to the mounting base (14). The baseband unit (11) fixed to the mounting base (14) is disposed to face a back part (132) of the antenna (13) and to form a space between the back part (132) and the first enclosure (111). The RF unit (12) fixed to the mounting base (14) is disposed in the space formed between the back part (132) of the antenna (13) and the baseband unit (11) and is coupled to a waveguide flange (132) of the antenna (13). Thus, for example, in a configuration of a point-to-point wireless apparatus in which an RF unit and a baseband unit are separated, restrictions on installation space of the apparatus can be facilitated.

Abstract: Antenna 2 and radio communication apparatus 1 include mount portions 9 and 15, flat proximity opposing surfaces 13 and 20, and waveguide portions 12 and 19 penetrating through proximity opposing surfaces 13 and 20, respectively. For example, in proximity opposing surface 13 of radio communication apparatus 1, choke groove 14 is formed outside waveguide portion 12. With mount portions 9 and 15 of antenna 2 and radio communication apparatus 1 abutted against and fixed to each other, proximity opposing surfaces 13 and 20 are set parallel to, and directly opposite to each other with a clearance interposed therebetween so that waveguide portions 12 and 19, opposite to each other and with a clearance, form a waveguide.
