Abstract
A microstrip printed circuit board antenna includes a printed circuit board (PCB)( ), a plurality of metal sheets ( ), and a plurality of microstrip traces ( ). A plurality of antenna units is provided on the PCB. Each antenna unit includes one metal sheet, and a plurality of microstrip traces. In each antenna unit, the metal sheet serves as a grounding plane and the microstrip traces serve as a signal unit. The microstrip traces are disposed on both top and bottom faces ( ) of the PCB. An end of each microstrip trace forms a conductive through hole ( ). Each conductive through hole electrically connects the microstrip trace with a corresponding microstrip trace on an opposite face of the PCB. The conductive through holes are sequentially electrically connected together by the microstrip traces, thereby forming a continuous conductive line. Thus, a size of the antenna unit is significantly reduced.
