Sažetak
Power combining in free space and beam scanning without phase shifters are two main advantages offered by arrays of oscillating antennas. An increase of the power radiated by the single antenna element is obtained by integrating a push-pull oscillator with two bipolar transistors in a rectangular opening inside a rectangular patch. This oscillating antenna 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 very good power combining efficiency are measured. The measured spectra are clean and stable. Electronic beam scanning is demonstrated. Symmetrical beam scanning around broadside direction is obtained for both arrays. 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.
