Ball 4, the metal throuth hole 5 for connecting radiating element and feed point.There are annular air gap flutings between earth plate and feed point.
Preferably, radiating element is made of two centrosymmetric rectangular metals；The length of each rectangular metal is
2.3mm, width 0.5mm.Size s slot as 0.25mm in the air gap.The feed point is identical by amplitude, and 180 ° of phase phase difference
Differential signal feed-in.
The present invention and the advantage of existing invention are:
1. making dipole antenna realize stereoscopic three-dimensional structure from planar structure, convenient for integrated；
2. bay is single layer structure, small in size, at low cost.
