Problems solved by technology

The size of the inverted F-shaped planar antenna module 1 in the prior art is relatively large (when used to transmit wireless signals of 2.5-2.7 GHz, its size is about 25 * 20mm 2 ), and the signal isolation (S parameter) between the first port 14 and the second port 24 is poor (S (2, 1), about -5.2dB, refer to Figure 1B )

Embodiment Construction

[0019] Certain terms are used in the description and claims to refer to particular elements. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. "Includes" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". In addition, the term "coupled" herein includes any direct and indirect means of electrical connection. Therefore, if it is described that the first device is coupled to the second device, it means that the first device may be directly electrically connected to the second device, or indirectly electrically connected to the second device through other devices or connection means.

Abstract

A meander slot antenna structure for transmitting a wireless signal is provided. The meander slot antenna structure includes a substrate, a ground element, a feed conductor and a couple conductor. The substrate includes a first surface and a second surface, wherein the first surface is opposite to the second surface. The ground element is disposed on the second surface, wherein a meander slot is formed in the ground element. The feed conductor is disposed on the first surface, wherein the feed conductor corresponds to the meander slot. The couple conductor is disposed on the first surface and coupled with the feed conductor, wherein a via passes through the substrate and electrically connects the couple conductor to the ground element.

Description

technical field [0001] The present invention relates to a slot antenna structure, in particular to an antenna module with a smaller size and better isolation and its meander slot antenna structure. Background technique [0002] Figure 1A It is an inverted F planar antenna (PIFA antenna) module 1 in the prior art, which includes a first inverted F planar antenna unit 10 and a second inverted F planar antenna unit 20 . The first inverted-F antenna planar unit 10 is F-shaped and has a first feed conductor 11 , a first radiator 12 and a first short-circuit element 13 . The first feed conductor 11 is connected to the first radiator 12 , the first short circuit element 13 is connected to the first radiator 12 , and the first short circuit element 13 is grounded. The second inverted-F planar antenna unit 20 is F-shaped and has a second feed conductor 21 , a second radiator 22 and a second short-circuit element 23 . The second feeding conductor 21 is connected to the second radia...
