This paper describes optimization of the planar ultra wideband dipole antennas, which are optimized for perfect matching and perfect impulse radiation characteristics. The optimization of the dipole shapes starts from the classical wideband dipoles, especially from elliptical and diamond shapes. These wideband dipoles have been analyzed and optimized with unsatisfactory parameters performance. This...
This paper presents two models of switched beam antennas that can be used in radio planning and interference mitigation studies based on Monte-Carlo analysis. The models are implemented in a sharing and compatibility study of two different radio systems that share the same geographical area and have neighboring frequency bands. The results agree very well with the one obtained using measured radiation...
A smooth-walled horn is often preferred over a corrugated horn due to easier and cheaper manufacturing. By optimizing the profile of the horn it is possible to obtain low cross polarization over a broad bandwidth. In this paper a very efficient method of profile definition, analysis and optimization for a stepped profile horn is described and applied to the design of a 20/30 GHz feed horn suited for...
