Abstract
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.
