Embodiment Construction

[0035] Please refer to figure 2 , figure 2 It is a schematic diagram of a slot antenna 2 according to an embodiment of the present invention. The main working frequency band of the slot antenna 2 is 2300MHz~2700MHz, and it includes a substrate 20, a radiator 22, a signal feeding section 24, a signal feeding end 25, a first extension 26 and a second extension 28. The substrate 20 includes a first surface 200 and a second surface 201 opposite to the first surface 200, which may be a substrate of FR4 or other materials. The radiator 22 is disposed on the first surface 200 of the substrate 20 and includes a first radiating section 220, a second radiating section 222, a third radiating section 224 and a fourth radiating section 226. Such as figure 1 As shown, the first radiating section 220, the second radiating section 222, the third radiating section 224, and the fourth radiating section 226 are respectively perpendicular to the adjacent radiating sections, that is, the fourth ...

Abstract

The invention relates to a slot antenna comprising a base plate, a radiation body, a single feed-in section, a signal feed-in terminal, a first extension part and a second extension part. The base plate comprises a first face and a second face; the radiation body is arranged on the first face of the base plate and forms a slot; the signal feed-in section is arranged on a position of the second face corresponding to the slot; the signal feed-in terminal is electrically connected with the signal feed-in part for transmitting signals; the first extension part is arranged at a first side of the signal feed-in section on the second face for increasing the frequency width of the slot antenna; and the second extension part is arranged on a second side of the signal feed-in section on the second face of the base plate for increasing the frequency width of the slot antenna. In the slot antenna, the first extension part and the second extension part are designed for increasing the frequency of the antenna, thereby achieving the purpose of the invention.

Description

Technical field [0001] The present invention relates to a slot antenna, in particular to a slot antenna that can reduce the area and increase the bandwidth. Background technique [0002] In recent years, due to the vigorous development of wireless communication, people's demand for wireless communication has increased day by day, and more and more information is transmitted through wireless networks. Therefore, the demand for bandwidth of antennas that dominate wireless signal transmission and reception has also increased. In addition, the lightness, thinness and shortness of the communication device has led to a reduction in design space, which has also become a consideration when designing antennas. [0003] Please refer to figure 1 , figure 1 It is a schematic diagram of a well-known slot antenna 10 used in a wireless network. The slot antenna 10 includes a substrate 100, a radiator 102 and a signal feeding section 104. The substrate 100 includes a front side and a back side. ...
