Phase detection of horn antenna arrays
2007 IEEE Antennas and Propagation International Symposium, 2007An simple approach for phase matching in horn antenna arrays is presented, in which a waveguide detector is used to measuring the phase distribution on the horn aperture plane. The relative phase differences can become almost the same by adjusting the phase shifter, thus phase matching is achieved.

The theory of array antenna design has matured such that the tools are now available to design elements with predictable performance and to verify this performance with high confidence. The antenna feed is of equal importance to the antenna element.
