Abstract

The present invention provides an antenna, comprising a reference ground and at least one radiation source, wherein the radiation source is adjacent to the reference ground to form a radiation gap between the radiation source and the reference ground , wherein the radiation source is electrically connected to the reference ground to ground the radiation source, thereby narrowing the bandwidth of the antenna. When an electromagnetic excitation signal is connected from a feeding point of the radiation source, the narrowing of the bandwidth of the antenna can prevent the electromagnetic wave signal received or generated by the antenna from being affected by the electromagnetic radiation frequency or frequency of the adjacent adjacent frequency band. Spurious radiation frequency interference.

Description

technical field

[0001] The present invention relates to an antenna, in particular to an antenna with an anti-interference setting, wherein the anti-interference method prevents the electromagnetic wave signal received or generated by the antenna from being interfered by adjacent electromagnetic radiation frequencies or stray radiation frequencies, thereby improving the anti-interference of the antenna interfere with performance. Background technique

[0002] ISM (Industrial Scientific Medical) Bands are unlicensed frequency bands defined by ITU-R (ITURadiocommunication Sector, International Telecommunication Union Radiocommunication Bureau) for use by institutions such as industry, science and medicine, which are used when using these frequency bands It is necessary to comply with a certain transmission power (generally the transmission power is lower than 1W) and not cause interference to other frequency bands. At present, the frequency bands used for microwave detection i...
