ABSTRACT:
A center fed half-wave dipole antenna system includes first and second end brackets that are separated by a center bracket. The center bracket and each of the end brackets include a plurality of electrically isolated terminals allowing the center bracket to be coupled to each of the end brackets via a pair of dipole lines that may contain multiple dipole wires. As such, the antenna system is able to increase the effective length of the dipole antenna in a reduced amount of space, thus reducing the mounting area requirements of the antenna system.
