Double-frequency reversed F-typed antenna

Abstract

The present invention relates to a double frequency antenna in a shape of reversed F. It includes a premier radiation unit, a secondary radiation unit and a third radiation unit. The premier radiation unit includes a premier long and short line. The secondary radiation unit includes a secondary long and short line, with the secondary long line opposite to the premier short line. The third radiation unit includes a premier, secondary and third radiation sections, the last two sections are the prolonged parts to the two ends of the premier one, and with clearance between the premier and the third sections. The premier and the secondary sections meet to the premier frequency at IEEE 802.11b / g and the third section meets to the secondary frequency at IEEE 802.11a. Therefore, the double frequency antenna in a shape of reversed F provided by the present invention can be accord with requirements of the prior norms and is provided with a function of dual operation frequency section, and is very practical.

Description

technical field [0001] The invention relates to an antenna, in particular to a dual-frequency inverted-F antenna with relatively large operating bandwidth, which meets the requirements of current standard bandwidth, and has the function of dual operating frequency bands. Background technique [0002] The vigorous development of wireless transmission has brought various products and technologies applied to multi-frequency transmission, so that many new products have the function of wireless transmission in order to meet the needs of consumers. The antenna is an important component used to transmit and receive electromagnetic wave energy in the wireless transmission system. Without the antenna, the wireless transmission system will not be able to transmit and receive data. Therefore, the role of the antenna is an indispensable part for wireless transmission. [0003] Choosing an appropriate antenna can not only help to match the appearance of the product and improve the trans...

AI Technical Summary

Problems solved by technology

[0005] Generally speaking, the operating bandwidth of the aforementioned antenna 1 is approximately between 5.15 GHz and 5.25 GHz. 5.85GHz, it can be seen that the existing antenna 1 can no longer meet the current needs, and most of today's antennas have the function of dual operating frequency bands or multiple operating frequency bands to improve the performance and applicability of the antenna

[0006] It can be seen that the above-mentioned existing antenna obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently.

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and the general products do not have a suitable structure to solve the above-mentioned problems. This is obviously related. The problem that the industry is eager to solve
