Abstract
An impedance matching device for matching the impedance of a pair of antennas to that of a common source. Impedance matching is achieved by a bifilar transformer having a plurality of mutually coupled windings, such windings being connected in series parallel relationship so as to provide a pair of parallel connected branches having a common leg, the antennas being connected to the respective branches so that each antenna sees the full reflected impedance of the source.
