Fig. 1 is the schematic diagram according to the antenna of preferred implementation structure of the present utility model and operation; And

Corresponding perspective view, vertical view and the sectional view of the simplification that Fig. 2 A, Fig. 2 B and Fig. 2 C are type antenna shown in Fig. 1.

Embodiment

Referring now to Fig. 1, Fig. 1 is the schematic diagram according to the antenna of preferred implementation structure of the present utility model and operation.

As can be seen from fig. 1, provide a kind of antenna 100.Antenna 100 is preferably the indoor type antenna, and particularly preferably is applicable to be arranged on ceiling 102.Yet, it should be understood that the operation requirements according to antenna 100, antenna 100 alternatively is applicable to be arranged on various indoor and/or outdoor surfaces.

As in enlarging section, 104 place's optimal viewing arrive, antenna 100 comprises broadband vertical polarization monopole radiation element, in this as example, is embodied as broadband vertical polarization planar monopole element 106.A plurality of horizontal polarization radiant elements that are embodied as the array 108 of four horizontal polarization dipoles in this as example roughly arrange concentrically with respect to one pole 106.

It should be understood that therefore antenna 100 forms dual polarized antenna, this dual polarized antenna can be by vertical polarization one pole 106 and horizontal polarization dipole array 108 corresponding operating simultaneously, and radiation simultaneously vertically reaches horizontal polarization radio frequency (RF) signal.Due to one pole 106 and the mutually orthogonal polarization of dipole array 108, one pole 106 and dipole array 108 are uncorrelated, thereby make antenna 100 be particularly suitable for the MIMO application.

It will also be appreciated that the structure of one pole 106 and dipole array 108 and arrange it is only exemplary, and multiple other execution modes of vertical polarization monopole radiation element and horizontal polarization radiant element and arrange it is also possible, as after this by illustrative.

One pole 106 and dipole array 108 preferably are arranged on the upper surface 110 of reflector 112, and wherein reflector 112 preferably forms the ground plane of antenna 100.The existence of reflector 112 is special characteristics of preferred implementation of the present utility model, and has produced some significant advantages in the operation of antenna 100.

The size of reflector 112, shape and position are used for controlling both radiation modes of one pole 106 and dipole array 108.In particularly preferred execution mode of the present utility model, reflector 112 is arranged to have protuberance in the first plane substantially vertical at the vertical axis 114 with one pole 106 with respect to one pole 106.In the execution mode of antenna shown in Figure 1, as example, reflector 112 is shown as the plane component that limits the plane vertical with the vertical axis 114 of one pole 106.

Dipole array 108 preferably is arranged so that each dipole all has protuberance at the vertical axis 114 with monopole radiation element 106 on substantially vertical the second plane, and the second plane is offset in the direction of the vertical axis 114 along one pole 106 from the plane limited by reflector 112.In the execution mode of the antenna shown in Fig. 1, as example, dipole array 108 is shown as including upright dipole structure, and it is vertical and raise with respect to the plane limited by reflector 112 that this upright dipole structure is arranged to vertical axis 114 with one pole 106.

The above-mentioned layout with respect to one pole 106 and dipole array 108 of reflector 112 causes forming the omnidirectional radiation pattern by one pole 106 and dipole array 108.This radiation mode makes antenna 100 be particularly suitable for being deployed as the antenna of ceiling Setup Type, as represented as the RF wave beam 116 presented by picture.And because one pole 106 has similar radiation mode with dipole array 108, so antenna 100 provides the level of good equilibrium and vertical polarization wave beam to cover in its operating environment.

Except the radiation mode that affects one pole 106 and dipole array 108, reflector 112 also is used for absorbing the spuious RF radiation between one pole 106 and dipole array 108, thereby has improved the isolation between one pole 106 and dipole array 108.

Therefore in addition, the existence of reflector 112 has improved the isolation of one pole 106 and dipole array 108 things peripheral with it, and has reduced the neurological susceptibility of 100 pairs of physics of antenna and electric external action.
