Abstract

To contribute to the improvement of a communication environment and a reception environment of radio and television by providing a device that reduces the influence of jamming, etc.SOLUTION: According to settings of a computer built into a radio communication device, radio waves of the same frequency as received radio waves are made to be received and simultaneously radiated from an antenna with an amplitude of the radio waves being in reverse phase instead of in phase. As a result, an interference phenomenon occurs in a space around the antenna, which reduces interference damage.SELECTED DRAWING: None

Description

本発明は、電波の特性と無線通信機の応用技術に関する。The present invention relates to radio wave characteristics and applied technology of a wireless communication device.

電波とは、振幅と周期性をもつという特性がある。
同一の周波数の電波が同一の空間に２つある場合、合成波による干渉現象が起こる。
干渉とは、２つの電波の位相が同じ場合（同位相）は、互いに強め合い増幅され２つの電波の位相が反対の場合（逆位相）は、互いに弱め合い相殺されるという現象である。Radio waves have the characteristics of having amplitude and periodicity.
When there are two radio waves of the same frequency in the same space, an interference phenomenon due to a composite wave occurs.
Interference is a phenomenon in which when the phases of two radio waves are the same (in phase), they are strengthened and amplified, and when the phases of the two radio waves are opposite (opposite phase), they weaken each other and cancel each other out.

妨害電波等による影響を軽減する装置を提供し、通信環境、ラジオ・テレビの受信環境の改善に寄与する。 It provides a device that reduces the effects of jamming radio waves, etc., and contributes to improving the communication environment and radio / television reception environment.

無線通信機に内蔵されているコンピューターの設定によって、受信電波と同一周波数の電波を電波の振幅が同位相ではなく逆位相になる状態で受信と同時にアンテナから放射されるようにする。
この結果、アンテナ周辺の空間で干渉現象が起こり妨害電波被害を軽減することができる。Depending on the settings of the computer built into the wireless communication device, radio waves of the same frequency as the received radio waves are radiated from the antenna at the same time as they are received in a state where the amplitude of the radio waves is not in phase but in opposite phase.
As a result, an interference phenomenon occurs in the space around the antenna, and damage to jamming radio waves can be reduced.
