Second Generation Quasi-Optical Combiners

Abstract

Millimeter-wave quasi-optical power combining schemes employing new and innovative architectures have been investigated with the objectives of building efficient arrays and addressing the specific shortcomings encountered during development. The importance of broadband wireless applications has been recognized through the implementation of array modulation schemes, taking into consideration noise, linearity and other relevant issues. Novel quadrature phase locked loop techniques for generating QPSK, 16-QAM and high order QAM modulation schemes have been developed. Omni-directional arrays using modified Vivaldi antennas, a monopole based Ku-band amplifier array with a gain of 5.4 dB, a Fabry-Perot resonator coupled oscillator array, an inclined plane horn antenna array and three-dimensional grating array structures were investigated.
