Abstract:
An antenna (10) is provided including a generally rectangular ground element (20) having a first end and a second end. The ground element (20) includes at least one hole (30, 30′) for mounting the antenna to a support structure. A generally rectangular radiating element (12) having a third end and a fourth end if parallel to the ground element (20) and separated from the ground element (20) by a space. A bend connects the first end of the ground element (20) to the third end of the radiating element (12). A coaxial cable includes a center conductor coupled to the radiating element (12) at a feed point and an outer conductor coupled to the ground element (20). The coaxial cable acts as a feed line that couples the antenna (10) to an external transmitter or receiver.
