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.

Microwave and Optical Technology Letters, 2008
AbstractPhased addition of currents from multiple dipole antennas is demonstrated for the first time at a wavelength of 10.6 μm. Coplanar strip lines are used to interconnect the antennas, preserving the phase of the individual infrared‐frequency currents, which are summed together at a common bolometric load.

Wideband Phased Array Antennas
2008 IEEE National Aerospace and Electronics Conference, 2008Slotted spiral antennas with a ground plane are designed to cover the frequency range 0.5-18 GHz. Various antennas incorporating Archemidan slotted spirals with a ground plane and dielectric thickness less than 100 um were designed, processed and tested at different frequency ranges using conventional PCBs as well as vertically interconnected and ...
