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.

Converter for planar antenna

A plane antenna comprises a power-supply circuit, a radiator circuit and an earthing conductor which are stacked respectively with a dielectric layer interposed between them, in which the power-supply and radiator circuits are made independent of each other as electromagnetically coupled to each other and at least one of the dielectric layers is formed with a foamed resin, whereby insertion loss can be reduced to remarkably improve the antenna characteristics. Only with the interposition of the foamed resin dielectric layer or layers, an effective separation is achieved between at least the power-supply circuit and the earthing conductor or the power-supply circuit and the radiator circuit, for a large extent improvement in the assembling ability.

Planar antenna

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.
