Description
Technical field
The present invention relates to antenna technical field, be specifically related to a kind of miniaturization LTE/WWAN antenna.
Background technology
LTE FDD and TD-LTE two is big, and standard is all based on OFDM(OFDM) technology, and 2G, 3G frequency spectrum in global range is crowded, the distribution causing LTE epoch wireless frequency spectrum is the most discrete.Meanwhile, two big standards support the MIMO(multiple-input, multiple-output of radio-frequency head respectively) and Beam-forming(beam shaping) technology, physical layout and performance indications to antenna for base station propose brand-new requirement.At present, the direction that external LTE multifrequency antenna is less towards space, performance is higher, more multiband is integrated is developed.Most products design structure is column, shaft-like, strip etc. in the industry, and antenna band requires to cover 698-960MHz, 1710-2700MHz.Owing to frequency band is relatively wide so overall dimensions is the biggest, when being such as applied to CPE product when application, badly influence the structure of product and the aesthetic property of outward appearance.
Summary of the invention
The problem that the present invention need to solve is to provide omnidirectional's high efficiency LTE/WWAN antenna that a kind of novel miniaturization that can be applicable to CPE is external.
The technical solution adopted in the present invention is: a kind of miniaturization LTE/WWAN antenna, including PCB substrate and the antenna radiation unit be located in PCB substrate；One side relative with antenna radiation unit in PCB substrate is provided with microstrip line, and described microstrip line realizes being electrically connected with by via conducting with antenna radiation unit；Described antenna radiation unit use dipole antenna form, be arranged on PCB substrate the same face couple with coupling expansion antenna high frequency bandwidth；Described coupling ground has spill limit, and its spill limit is oppositely arranged with antenna radiation unit；Described microstrip line is respectively provided on two sides with ground wire, and described ground wire realizes being electrically connected with being turned on by via with coupling；The resonant frequency of described antenna is 698MHz-960MHz, 1710MHz-2700MHz；Described antenna connects SMA radio-frequency joint by coaxial cable and realizes antenna feed, and described coaxial cable core connects microstrip line, the coupling ground of aerial radiation elemental area on external shielding layer connecting PCB board.
Match circuit is had it is furthermore preferred that be connected between described microstrip line and ground wire.
Preferably, described antenna is external antenna.
Compared with prior art, the beneficial effects of the present invention is:
(1) inventive antenna introduces microstrip feed line as antenna current feed port, antenna current feed port is transferred to the opposite side of antenna, it is to avoid the incoordination of the structure that conventional dipole sub antenna causes from middle outlet；
(2) described antenna radiation efficiency is high, covers frequency range width, and integrated antenna size reduces about 40%, solves the problem that the most external LTE antenna size is the biggest；
(3) described antenna structure is simple, it is easy to accomplish, the R&D cycle is shorter, realizes cost savings in all its bearings.

Detailed description of the invention
Understanding the technology contents of the present invention for convenience of those skilled in the art, below in conjunction with embodiment and accompanying drawing, the present invention is described in further detail.
As shown in Figure 1, 2, the medium substrate of LTE/WWAN antenna described in the present embodiment uses double-sided PCB board 10, pcb board 10 front cabling includes coupling ground 11 and antenna radiation unit 12, reverse side cabling includes microstrip line 13 and is located at the ground wire 14 of microstrip line 13 both sides, between microstrip line 13 with ground wire 14, form two match bit in parallel, can mate in order to the low frequency regulating antenna at this position matching connection circuit.Its electric conductivity is ensured by via 17 conducting between microstrip line 13 and radiating element 12.The ground on pcb board two sides connects also by via conducting.
The present embodiment antenna connects SMA radio-frequency joint 16 by 50 ohm coaxial cable 15 and realizes feed.The heart yearn of coaxial cable 15 is connected to the microstrip line in 50 Europe, and the screen layer of coaxial cable 15 outer layer is welded to the ground wire 14 with microstrip line coplanar.The upper shell of above-mentioned antenna installing forms external antenna, and volume is little, covers frequency range width, and efficiency is high.It is particularly suitable for the wireless terminal accessing devices such as CPE to use.
Such as Fig. 3, the most described antenna achieves double resonance at 698MHz-960MHz, 1710MHz-2700MHz.
