Description

technical field [0001] The present application relates to the technical field of antenna communication, in particular to an antenna device and communication equipment thereof. Background technique [0002] The transmission and reception of radio waves need to be completed by the antenna. As a key component of the communication front end, the importance of the antenna is self-evident. At present, in order to achieve different business needs in ultrashort wave communication, a radio station often needs to be equipped with multiple antennas. However, the carrying radio is limited by the volume of the carrier, and multiple antennas will interfere with each other, making it impossible to work at the same time, and frequent replacement of antennas is not suitable for actual use scenarios. Therefore, the development of ultra-wideband antenna technology is of great significance to ultra-short wave communication. [0003] At present, there have been ultra-wideband omnidirectional a...

Problems solved by technology

[0003] At present, there have been ultra-wideband omnidirectional antennas applied to ultrashort wave communication, but there is often a situation: if the antenna radiator is too long, the high-frequency horizontal plane gain of the antenna will be very low; if the antenna radiator is too short, it will be As a result, the gain and antenna efficiency in the low frequency band will decrease rapidly

Therefore, the existing ultra-wideband omnidirectional antennas cannot broaden the operating frequency band of the antenna while taking into account the antenna efficiency
