Problems solved by technology
[0002] In the prior art, the frequency radiated by a slot antenna with a structure can only cover a single frequency band. If you want to expand the impedance bandwidth with a return loss of 10dB, you must use a variety of slot antennas with different structures. to cover multiple frequency bands
This will bring great inconvenience to users' multi-band requirements, and also bring pressure to increase costs for users
Therefore, how to realize a slot antenna with a structure that can cover multiple frequency bands and have good radiation performance is a big challenge in the frequency range that meets the wireless communication standards.

A slot antenna disposed on a substrate including a first surface and an opposite second surface includes a feeding portion, a first radiation portion, a second radiation portion, and a third radiation portion. The feeding portion is disposed on the first surface, and operable to feed electromagnetic signals. The first radiation portion electronically connected to the feeding portion is circular-shaped and disposed on the first surface. The second radiating portion is disposed on the second surface and defines a slot. The second radiation portion couples the first radiation portion to radiate the electromagnetic signals. The third radiation portion is ring-shaped and disposed on the second surface. The third radiation portion couples the first radiation portion to radiate the electromagnetic signals. The first radiation portion, the second radiation portion, and the third radiation portion respectively radiate electromagnetic signals with different frequencies. The second radiation portion is grounded.
Description
technical field [0001] The invention relates to an antenna, in particular to a slot antenna and a slot antenna array. Background technique [0002] In the prior art, the frequency radiated by a slot antenna with a structure can only cover a single frequency band. If you want to expand the impedance bandwidth with a return loss of 10dB, you must use a variety of slot antennas with different structures. to cover multiple frequency bands. This brings great inconvenience to the user's multi-band requirements, and also brings the pressure of increasing costs to the user. Therefore, how to realize a slot antenna with a structure that can cover multiple frequency bands and have good radiation performance is a big challenge in the frequency range that meets the wireless communication standards. Contents of the invention [0003] In view of this, it is necessary to provide a slot antenna that can achieve multi-band coverage and has good radiation performance. [0004] In additio...
