1. A substantially planar antenna having a dipole structure for receiving and transmitting high-frequency signals, comprising:

  • a substrate;

    a first feed line disposed on a first side of the substrate;

    a second feed line disposed on a second side of the substrate;

    at least two dipoles, each dipole bifurcated so as to have a first half disposed on one side of the substrate and a second half disposed on another side of the substrate;

    wherein;

    one half of each dipole is connected to one of the feed lines, and the other half of each dipole is connected to the other feed line; and
