  • Converter for planar antenna
    Patent number: 4999592
    Abstract: A converter for use with planar antennas has a probe projected into an input part of waveguide structure as extended along a plane including a circuit board in a body of the converter, an opening of which input part being disposed in parallel to the plane, whereby the converter input part is allowed to have a thickness limited within the thickness of the converter body to remarkably reduce the entire thickness for effectively realizing a minimization in the thickness of the converter.

  • Planar microwave antenna having high antenna gain
    Patent number: 4713670
    Abstract: A microwave plane antenna comprises a plurality of pairs of antenna elements connected at their one end to a power supply circuit and respectively including at the other terminating end an impedance-matched patch antenna means, whereby signal energy remaining at the terminating ends of the antenna elements is caused to be effectively utilized as radiation energy, and any power loss is restrained for a high antenna gain and improved aperture efficiency.
