A patch antenna integrated with a transistor oscillator and a line impedance transformer has been used as a building element for two-element power combining arrays. Arrays coupled in E and H planes have been theoretically and experimentally investigated. The inter-element distance in the arrays has been optimized to obtain in-phase operation and mutual injection locking. High EIRP and excellent power combining efficiency are measured. The measured spectra are clean and stable. Electronic beam scanning is demonstrated. The co-polarization and cross-polarization radiation patterns are measured for the case of broadside radiation and scanned positions of the main beam. The cross-polarization levels are low.Mikrotrakasta patch antena unutar koj...
