Embodiment
Understand technology contents of the present utility model for convenience of those skilled in the art, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, 2, the antenna of diversity reception described in the present embodiment comprises pcb board 1, and antenna cabling and floor file region are set respectively on PCB, and in the present embodiment, floor file region and antenna cabling are separately positioned on the two sides of pcb board 1.On floor file region, be provided with semicircular ring composition resonant ring structure 3 of several concentric and shared diameters, in the semicircular ring of each concentric and shared diameter, be equipped with opening 30, these openings are located along the same line.Described antenna cabling 2 is rectangle radiating element, from radiating element dual-side many breach 20 that are inwardly crisscross arranged respectively; Radiating element bottom is respectively step shrinks from two side direction centers, and converges to distributing point 4.
In this enforcement, resonant ring structure is made up of the breach resonance concentric semicircles ring of four shared diameters, when making, directly on pcb board, obtains by etching.Antenna radiation unit adopts a passband antenna that is operated in designated frequency band, this passband can comprise all frequency ranges that UE supports, after adding the structure of resonant ring, resonant ring can form the stopband with filtering, isolation and anti-jamming effectiveness between each reception frequency range of these frequency ranges, and the formation of stopband is the sign that split collar produces standing wave resonance.The difference of the working frequency range of the required antenna of foundation, the position of stopband and width can be adjusted accordingly by radius, slit width and the groove width of controlling resonant ring.
When concrete enforcement, can between distributing point 4 and motherboard circuit, stay figurate match circuit, be used for adjusting the impedance matching of antenna.In order to strengthen coupled resonance effect, can the structure of resonant ring is near as much as possible apart from the edge in floor file region and feedback point, can strengthen like this resonance current size on line of rabbet joint surface, thereby increase the anti-jamming effectiveness of designated frequency band.
Fig. 3 is antenna embodiment return loss plot figure described in the utility model.As seen from Figure 3, adopt the antenna of the utility model structure, impedance bandwidth at 869～894MHz, 1805～1880MHz, these four band antennas of 2110～2170MHz is respectively 25MHz, 75MHz, 60MHz and 70MHz, three frequency ranges of stopband are respectively: 894～1805MHz, 1880～2110MHz, 2170～2620MHz, three the impedance mismatching bandwidth corresponding with it are respectively: 911MHz, 230MHz and 450MHz, antenna is respectively 6dBi, 6.2dBi, 6.3dBi and 6.2dBi in the gain of 882MHz, 1843MHz, 2140MHz and 2655MHz.Known, the antenna structure of this surface filtering can be realized the miniaturization of antenna in realizing high-gain, and compared with the microstrip antenna of traditional paster structure, size can be decreased to 20%.
When concrete enforcement, can adopt for supporting the different end product of different frequency range combination, can adjust by regulating the size (diameter, groove width and slit width) of resonant ring structure, the number of plies that medium mixes and reserved antenna match to change impedance mismatching impedance matching frequency band and the bandwidth of antenna.
These are only specific embodiment of the utility model, do not coming off in the utility model design situation, any minor variations that the utility model is done, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
