Abstract
A stripline antenna for micro waves fed from one end of plural antenna arrays for easy arrangement of feeding elements, and coupled with a shielded stripline branching circuit for preventing antenna beam pattern from being disturbed by the reflected energy and for radiating the supplied energy as an effective electromagnetic wave beam.
Claims3
A strip-line antenna for microwaves wherein:
- one or more strip-line of zig-zag type for microwaves are attached onto one surface of a first dielectric plate;
- a metal conductor is attached to the other surface of the first dielectric plate;
- respected input ends of said antennas of zig-zag type are connected to output terminals of a strip-line branching circuit of a shielded construction, said strip-line branching circuit of shielded construction is arranged such that a second dielectric plate, onto which another metal conductor is attached, is attached onto an unshielded strip-line branching circuit attached onto said one surface of said first dielectric plate;
- and
- input terminals of said strip-line branching circuit of shielded construction are connected to a central conductor of a coaxial feeding cable.
