Example Embodiment

[0017] To facilitate those skilled in the art to understand the technical content of the present invention, the present invention will be further described in detail below with reference to the embodiments and the drawings.

[0018] Such as figure 1 , 2 As shown, the dielectric substrate of the LTE / WWAN antenna in this embodiment adopts a double-sided PCB board 10. The front wiring of the PCB 10 includes the coupling ground 11 and the antenna radiating unit 12, and the reverse wiring includes the microstrip line 13 and The ground wires 14 on both sides of the microstrip line 13 form two parallel matching positions between the microstrip line 13 and the ground wire 14, and a matching circuit can be connected at these positions to adjust the low frequency matching of the antenna. The microstrip line 13 and the radiation unit 12 are connected through the via 17 to ensure their conductivity. The grounds on both sides of the PCB are also connected through vias.

Abstract

The present invention discloses a miniaturized LTE / WWAN antenna. The PCB antenna includes a substrate, a substrate side of the antenna radiation element and the coupling, the other side of the microstrip line is set and the corresponding ground wire. Microstrip antenna radiating element by electrically conductive vias connected. Between the microstrip line and the ground can be connected to the matching circuit. SMA RF connector to connect the antenna to achieve the antenna feed through coaxial cable, the installation of the enclosure as an external antenna. Compared with the prior art, the antenna structure is simple and easy to implement, shorter development cycles and achieve cost savings from all aspects.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a miniaturized LTE / WWAN antenna. Background technique [0002] Both the LTE FDD and TD-LTE standards are based on OFDM (Orthogonal Frequency Division Multiplexing) technology. However, the global spectrum congestion of 2G and 3G has led to a very discrete distribution of wireless spectrum in the LTE era. At the same time, the two standards respectively support MIMO (multiple-input multiple-output) and beam-forming (beam-forming) technologies at the radio end, and put forward new requirements for the physical layout and performance indicators of base station antennas. At present, the external LTE multi-band antenna is developing in the direction of smaller space, higher performance, and more frequency band integration. Most of the product design structures in the industry are columnar, rod-shaped, strip-shaped, etc., and the antenna frequency band is required to cover 698-960MHz...
