A compact, low profile dipole antenna assembly includes first and second linear radiating elements that form the positive and negative sides of the dipole antenna, and a balun that extends in parallel with the second radiating element, i.e., the negative side of the dipole antenna. The second radiating element is connected to ground at one end and is an open circuit at an opposite end. A main feed line, which is part of the balun, also connects to a common ground with the second radiating element. The balun and the connection to ground act as an impedance transformer, and the second radiating element acts as the negative side of the dipole antenna as well as a ground plane for the balun. The balun and the second radiating element share a volume with the second radiating element electrically shielding the balun, and the main feed probe connecting to ground within the shared volume. |
