Abstract

A micro antenna structure composed of a base plate and an antenna structure, a grounding surface and a clear space are formed on the base plate. The antenna structure is provided in the clear space and includes a radiation element and a fixing plate; the fixing plate is made of material for making a printed circuit board, while the radiation element is made from copper foils and is laid out linearly on the fixing plate. With this structure, the problem of having complicated procedure of processing and high cost of a conventional micro chip antenna can be eliminated here, and a good effect can be attained by using minimum space; thereby the weight and volume of a mobile communication product can be reduced but a good effect can be attained.
