Problems solved by technology

In addition, the antenna itself does not have a filtering function, which will cause some unnecessary frequency band signals to be transmitted or received, and it is a waste of space to place two passive devices at the front end of the radio frequency system. tor and the function of the antenna as a filter antenna
[0003] With the continuous development of mobile communications, China has released the future 5G millimeter wave frequency band (24.75-27.5GHz) in recent years. There are still few researches on filter antennas, and the society urgently needs filter antennas for millimeter frequency bands

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to the field of antennas. Background technique [0002] Filters and antennas are two important passive components at the front end of an RF system for wireless devices. The function of the filter is to only allow the signals of a part of the frequency band to pass through and suppress the signals of other frequency bands. With the development of wireless communication, there are many frequency bands of antennas. In order to filter the signals of these different frequency bands, low-pass filters and high-pass filters are used. Filters, band-pass filters, band-stop filters, etc., among which the most widely used is the band-pass filter. In addition, the antenna itself does not have a filtering function, which will cause some unnecessary frequency band signals to be transmitted or received, and it is a waste of space to place two passive devices at the front end of the radio freq...
