  • Planar antenna with active circuit block
    Patent number: 5083132
    Abstract: A planar antenna has an active circuit block, the whole or part of which is internally mounted to a planar antenna body so that connecting terminal of the block will be connected to a feeding point on power supply plate of the antenna body. Dimensional minimization of the entire antenna can be thereby attained and noise figure of the active circuit can be simultaneously reduced.
    Type: Grant

  • Plane antenna assembly
    Patent number: 4801943
    Abstract: A plane antenna assembly comprises a plurality of antenna bases and a signal composing means including amplifiers each connected to output part of each antenna base for composing respective outputs of the antenna bases amplified through the amplifiers, whereby a composite antenna output is obtained in correspondence to the number of the antenna bases and in an excellent S/N ratio.

  • 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.
