A receiving phased array antenna topology based on Mutually Coupled Harmonic Self-Oscillating Mixers

A design of a receiving 4x1 element phased antenna array based on Mutually Coupled Third Harmonic Self-Oscillating Mixers has been presented. The use of the third harmonic of the self-oscillation allows higher beam steering angles without extra circuitry showing the potential these multifunctional circuits have. The experimental behavior obtained with the receiving phased antenna array has been compared with the simulated results, at the optimum working point of the inner elements. A good agreement in the beam scanning between the simulations and measurements has been shown.
