Abstract
The present disclosure aims to provide an antenna directivity adjustment apparatus and an antenna directivity adjustment method capable of preventing an antenna gain from being reduced and easily adjusting a direction of an antenna. An antenna directivity adjustment apparatus (1) includes: a second antenna (2) that is opposed to a radiation surface (100a) of a first antenna (100) and receives radio waves output from the first antenna (100); and an output unit (3) that is provided in the second antenna (2), converts a first beam width of the received radio waves into a second beam width wider than the first beam width, and outputs the radio waves having the second beam width.

An antenna directivity adjustment apparatus comprising:
- a second antenna that is opposed to a radiation surface of a first antenna and receives radio waves output from the first antenna;
- and
- an output unit that is provided in the second antenna, converts a first beam width of the received radio waves into a second beam width wider than the first beam width, and outputs the radio waves having the second beam width.
An antenna directivity adjustment method in an antenna directivity adjustment apparatus, the method comprising:
- receiving radio waves output from a first antenna by a second antenna that is opposed to a radiation surface of the first antenna;
- converting a first beam width of the radio waves received by the second antenna into a second beam width wider than the first beam width;
- and
- outputting radio waves having the beam width after the conversion.
