The pull tab has a mounting hole (311) assembling the pull tab to the electrical connector, and a cavity (321) for a cable of the electrical connector extending therethrough.

Abstract: A dual band antenna (1) includes a printed wiring board (PWB) (20). The PWB has an antenna trace (10) and a grounding plate (30) respectively disposed on opposite surfaces (20a, 20b) of the PWB. The antenna trace includes a radiating arm (100) and a matching means (13). The radiating arm includes a meandering segment (12) and a linking segment (11). The linking segment links two points of the meandering segment, thereby forming a closed loop. Because of the closed loop, the radiating arm has two transmission paths, one longer path, which does not include the linking segment, and one shorter path, which does include the linking segment. The dual band antenna, therefore, is capable of operating at two different frequency bands because of the two paths of the radiating arm.

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 (10, 12) of the PCB. An end of each microstrip trace forms a conductive through hole (4). 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.
