Abstract :
A feed structure for an aperture coupled patch antenna is analyzed for applications in quasi-optical power combining arrays. The antenna feed provides a means of separating the active components from the radiating elements using a brick approach employed in the construction of phased array antennas. Simulated results show the applicability of the feed at Ka-band. Furthermore, measured results, which verify simulations performed at X-band, are presented.
