First Commercially Viable Compound PxM Loop Antenna
March 16, 2010
Founded in March 2008 Chief Scientist has background at NASA/JPL Developing two-dimensional compound antennas CPL™ technology Reference designs available early 2010
Small antennas Greater efficiency Wider bandwidth Easy to manufacture
Dockon Confidential
C = Compound Field Antenna◦ Excites both the TE and TM radiators concurrently
P = PxM ◦ Electric dipole moment, cross product magnetic dipole
moment
L = Loop◦ Loop-based antenna
Higher gain Smaller footprints/form factors Spatial diversity Flexibility in design parameters Size Shape Volume
Highly efficient radiator Low return loss Low VSWR Typical efficiency is +90 percent
Widest bandwidth possible More than 1 octave with positive gain Exclusive wideband matching network
Low-cost printed circuit technology Readily adaptable to most applications Common printed film platforms Stand alone component Easily manufactured techniques
