Penetrate the lower section of paster;Inverse-T-shaped open slot is provided with plane earth;The radiation patch is a part of for face structure, remainder
For cable architecture.
Further, main radiator and and feeding transmission line between using smooth curve attachment structure connection.
Further, the smooth curve attachment structure is two sections in 90 degree of tangent circular arcs of tie point, arc radius
For 2mm.
Further, a length of 18mm of the substrate, a width of 12mm, thickness is 1.6mm.
Further, the main radiator part of radiation patch is cable architecture, and remainder is face structure.
Further, radiation patch is one of the forming.
Beneficial effects of the present invention include it is following some:
Small-sized, the only 18mm × 12mm × 1.6mm of the antenna element, is highly the thickness of dielectric-slab (i.e. substrate)
1.6mm, small volume, simple structure, low cost, and antenna gain are high.
Also, the working band of antenna is in 2.37GHz-2.8GHz and 3.6GHz-12GHz, the purposes ratio of the antenna system
It is broad, the need of WLAN (2.45GHz), WiMAX (5.25-5.85GHz) and UWB (3.96-10.6GHz) application can be met
Ask.
Secondly, the structure of wire-board junction is more simpler than comprehensive antenna structure, and weight is lighter, and save after linearizing
Space can lay rectification circuit and match circuit so that whole antenna system is more compact, and cost is lower.
