Embodiments in accordance with the invention include a linearly polarized dipole antenna with an unbalanced microstrip feed line. More specifically, embodiments in accordance with the invention utilize a fed dipole connected to a microstrip feed line, and separated a gap distance from a parasitic dipole not connected to the microstrip feed line. When an electrical signal is input to the microstrip feed line, the microstrip feed line creates a current flow in the fed dipole which induces a nearly equal current on the parasitic dipole that is out of phase. The result is a current flow, I, in the same direction in both fed and parasitic dipoles allowing for efficient radiation of the linearly polarized dipole antenna. Embodiments in accordance with the invention eliminate the need for a balun circuit thereby reducing the size, complexity and feed loss of the feed circuit. Embodiments in accordance with the invention are effective for dipoles with relatively small ground planes.
