Connection structure for antenna apparatus and wireless communications apparatus

Abstract

An antenna (2) and a wireless communications apparatus (1) includes: mount portions (9, 15); flat proximate opposing surfaces (13, 20); and waveguide portions (12, 19) penetrating the proximate opposing surfaces (13, 20). For example, in the proximate opposing surface (13) of the wireless communications apparatus (1), a choke groove (14) is formed outside the waveguide portion (12). With the mount portions (9, 15) of the antenna (2) and the wireless communications apparatus (1) abutted and fixed to each other, the proximate opposing surfaces (13, 20) are directly opposed parallel to each other with a gap, and the waveguide portions (12, 19) are opposed to each other across the gap, forming a waveguide.

Description

technical field [0001] The present invention relates to a connection structure between an antenna device and a radio communication device. Background technique [0002] In a mobile communication system such as a mobile phone system, an access network for connecting radio base stations is constructed. An access network using radio communication by means of microwaves has the advantage of low network construction costs and flexibility in that radio base stations can be installed. A radio communication device for constructing such an access network includes: an antenna device installed in an unobstructed, high-altitude place such as a steel tower, a roof of a building; a radio communication device installed near the antenna device; and An indoor device that is separate from these and installed indoors to perform modulation and demodulation of transmission signals. [0003] The antenna device and the radio communication device transmit and receive high-frequency signals via th...

Problems solved by technology

However, if there is a gap between the waveguide portion of the antenna device and the waveguide portion in the housing of the radio communication device, a high-frequency signal leaks out of the waveguide from the gap, resulting in signal loss when the high-frequency signal is propagated.
