About Microstrip Antennas

Abstract

The electrical characteristics of a microstrip antenna are considered. Its design and electrical characteristics are compared with design and electrical characteristics of volume self-complementary antennas and an antenna located on the faces of a lying rectangular pyramid. The method of a complex potential is used for an analysis of the substrate influence on the properties of this antenna. In accordance with the results of comparing the characteristics of linear radiators with different current distributions, the design of a microstrip antenna with an in-phase distribution was proposed, which ensures operation in a wide frequency band.
