A loop antenna for communication is provided, which includes a microwave substrate, being a hexahedron; a first conductive layer, disposed on an upper surface of the substrate for forming a first loop; a second conductive layer, disposed on a first side surface of the substrate, and electrically connected to a feed-in point and a ground point; and a third conductive layer, disposed on a lower surface of the substrate for forming a second loop. The first conductive layer and the second conductive layer are electrically connected at the junction between the upper surface and the first side surface, and the second conductive layer and the third conductive layer are electrically connected at the junction between the first side surface and the lower surface. The antenna also has an appropriate bandwidth for wireless communication application.

Coupled-loop chip antenna

A GPS (Global Positioning System) antenna module includes a substrate, a first insulating layer, and a second insulating layer. The substrate is set on a bottom surface of a patch antenna. The first insulating layer is coated on the substrate and a layout circuit is formed thereon. A plurality of electronic elements are integrated on the substrate according to the layout circuit. Furthermore, the second insulating layer is coated on the first insulating layer to completely shield the electronic elements integrated on the substrate. Hence, the distance between the electronic elements and the antenna of the present invention can be shortened, space on the PCB and in the shielding case is saved. Moreover, an optimal high frequency character can be achieved, the volume of the antenna module is effectively reduced, the process is simplified, and production costs are reduced.

GPS antenna module and manufacturing method thereof

An antenna module has a PCB with a plurality of contacts, a support element, and an antenna module. The support element has a support portion extended downwardly therefrom. The antenna module is connected with the support element. The antenna structure has a metal support element fixed on the PCB with a plurality of contacts. The support element is used to support an antenna module for electrically connecting the antenna module on the PCB with the contacts. When the antenna module connects to the PCB, the antenna contact does not project out the bottom side of the PCB. Therefore, the bottom side of the PCB is level. The antenna structure has a metal support used to shield the noise interference between the antenna module and the PCB.

Antenna structure

An integrated active satellite antenna module has a low loss filter, a low noise amplifier, a switch, a chip, two input ends and an output end. A front-end microwave circuit is used for resolving the mutual coupling effect between the satellite antenna and the other antennas operating at any other frequencies in an integrated active satellite antenna module, and furthermore it provides the simultaneous operating condition for the individual antenna by improving the isolation level between the satellite frequency band and the other frequency band.
