Embodiment Construction

[0032] Please refer to FIG. 2 , which is a schematic diagram of a multi-layer panel antenna 38 of the present invention. The multi-layer panel antenna 38 includes a first stacked layer 40 , a second stacked layer 50 , a printed circuit board 64 and a feed line 72 . The first stacked layer 40 includes a first A-slab layer 42, a first A-packed layer 44, a second A-slab layer 46, and a second A-packed layer 48; the second stacked layer 50 includes a first B-slab layer 52 , a first B packing layer 54 , a second B flat plate layer 56 and a second B packing layer 58 . The first stacked layer 40 and the second stacked layer 50 enable the panel antenna to achieve broadband effect. The upper layer of the printed circuit board 64 is a ground layer 66, and its underside is a base plate (substrate) 68. The underside of the base plate 68 has a microstrip line 70, which is electrically connected to the feeding line 72, and thus receives the radio signal. enter. The ground layer 66 has a ...

Abstract

A multi-layer planar antenna capable of providing dual-frequency services to meet the requirement of simultaneously transmitting two frequencies with one antenna. The multilayer planar antenna includes a printed circuit board and two stacked layers. The printed circuit board includes a base plate, a metal layer is arranged on the upper side of the base plate, and a microstrip line is arranged on the lower side of the base plate. There are two slots on the metal layer, and the microstrip line is used to transmit radio signals to the two slots to generate resonance between the two slots and the stacked layers covering it, and the radio signals will be perpendicular to the two slots. The direction of the second stack layer is sent out to achieve high directivity.

Description

technical field [0001] The invention provides a multi-layer planar antenna, in particular a multi-layer planar antenna capable of providing dual-frequency services. Background technique [0002] The vigorous development of the Internet has enabled the rapid exchange and accumulation of data and information, and the efficient dissemination and sharing of a large number of technologies and knowledge. In recent years, the rapid development of wireless network (wireless network) has allowed users to access network resources anytime and anywhere, enabling information development to penetrate into every aspect of work and life. One of the characteristics of a wireless network is to get rid of the shackles of the physical network transmission line in the wired network, so that the terminal functions of the network can use electromagnetic waves or infrared rays to transmit data wirelessly, so as to network to the wireless network and access network resources. In a wireless network ...
