Description

Columnar antenna and its application
Technical field
The present invention relates to field of antenna, are in more detail related to a columnar antenna and dash forward in the installation of the columnar antenna It breaks shielding space and maintains the method for the communication stability of the columnar antenna and corresponding structure.
Background technology
Antenna is in a wireless communication device as the component for emitting or receiving electromagnetic wave, in radio communication, broadcast, electricity It is widely used in the engineering system for using electromagnetic waves to transmit information depending on, radar, remote sensing etc..Since antenna comes out, adapt to In different application scenarios, current antenna system is various, each has something to recommend him.It is respectively in civil antenna as shown in FIG. 1A and 1B The structural schematic diagram of current application more extensive columnar antenna 10P and plate aerial 20P, wherein columnar antenna 10P include One circuit board 11P, one refers to a column emission source 13Ps of the panel 12P and one perpendicular to circuit board 11P, wherein should It is arranged to using conductive material with reference to panel 12P and is attached at circuit board 11P, wherein this is further with reference to panel 12P It is equipped with a primary radiation hole 121P, the wherein column emission source 13P extends from circuit board 11P and via the primary radiation hole 121P pass through this refer to panel 12P, with further reference to Fig. 2, wherein this refer between panel 12P and column emission source 13P in A radiating slot 122P is formed in the 121P of the primary radiation hole, such columnar antenna 10P is then from radiating slot 122P with the column A radiation space 14P is formed with to axis centered on shape emission source 13P, in effectively transmitting signal in radiation space 14P.Ginseng Examine plate aerial 20P shown in Figure 1B, wherein plate aerial 20P includes a circuit board 21P, one with reference to panel 22P with And one be parallel to the flat-plate emission source 23P for referring to panel 22P, wherein this is arranged to reference to panel 22P using conduction material Expect and is attached at circuit board 21P.It is understood that in structure, due to the column emission source of columnar antenna 10P 13P is extended vertically in circuit board 11P, relative to the plate aerial 20P for tending to two-dimension plane structure, the columnar antenna 10P tends to expend the installation space of bigger as communication component in actual installation, thus small-sized succinct nowadays pursuing Appearance aesthetic trends under, columnar antenna 10P is gradually replaced by plate aerial 20P.
