Integral antenna assembly for a radio and method of manufacturing

摘要

Strips (220) of thin metallic material forming pairs of arms on an elongated dielectric tube (110) form a radiator portion of an antenna assembly. A first radiator plate (310) and a second radiator plate (320) are capacitively coupled to respective hot capacitive plate (270) and ground capacitive plate (280) on opposite sides of the dielectric tube and formed in a single etching step to improve manufacturability, reliability and cost of a radio.
