TITLE
Characteristics of a Circular Polarization Plane Antenna with Grounded Cylindrical Collar
ABSTRACT
This paper presents that a novel structure is given for elimination of cross-sectional radiation. Effective ways have not been given conventionally for reduction of cross-sectional radiation. A plane antenna is made of stripline antenna with feed- and reactance-elements, and the ground plate for circular polarization plane antenna. A quarter wavelength stripline with short circuit termination is provided around an antenna. This element provides capability of elimination of cross-sectional radiation from the antenna. By 3D computer simulation, the directivity is enhanced around 1 dB compared to an original antenna without cylindrical collar. It shows that about 1/3 of total energy radiation is transferred from cross-sectional directions to z axis direction.
