Microstrip array antenna
First Claim
1. A microstrip array antenna comprising:
- a dielectric substrate formed with a conductive ground plate at a back surface thereof; and
strip conductors formed on a front surface of said dielectric substrate;
said strip conductors including a linear main feeding strip line, and a plurality of array elements connected to said main feeding strip line, said array elements being disposed at least one of both sides of said main feeding strip line at a predetermined interval along a longitudinal direction of said main feeding strip line,each of said array elements including a sub-feeding strip line connected to said main feeding strip line, a rectangular radiating antenna element connected to a terminal end of said sub-feeding strip line, and a stub connected to said sub-feeding strip line,said stub being disposed between a connecting position between said main feeding strip line and said sub-feeding strip line and a connecting position between said sub-feeding strip line and said radiating antenna element.

Abstract
The microstrip array antenna includes a dielectric substrate formed with a conductive ground plate at a back surface thereof, and strip conductors formed on a front surface of the dielectric substrate. The strip conductors includes a linear main feeding strip line, and a plurality of array elements connected to the main feeding strip line, the array elements being disposed at least one of both sides of the main feeding strip line at a predetermined interval along a longitudinal direction of the main feeding strip line. Each of the array elements includes a sub-feeding strip line connected to the main feeding strip line, a rectangular radiating antenna element connected to a terminal end of the sub-feeding strip line, and a stub connected to the sub-feeding strip line. The stub is disposed between the main feeding strip line and the radiating antenna element.
