Abstract: Disclosed is a system and method for a 24-GHz phased array for indoor smart radar comprising at least 6 horizontally placed antenna elements as a vertically placed 5-element series-fed microstrip patch array. The beam of the phased array can be continuously steered on the H-plane to different directions through a novel vector control array. Each element can adjust the phase and amplitude of the corresponding element of the horizontally placed linear array. The phased array system of the present invention may be fabricated on a single printed circuit board (PCB), and PIN diodes are used to realize beam steering by modulating the decomposed received signal. In order to compensate for the loss of the vector control array and reduce the noise figure, six low noise amplifiers (LNAs) are also used in the array. The present invention has the ability to continuously steer the beam on the H-plane.

Abstract: Disclosed is a system and method for a complex domain radio frequency (RF) frontend, adaptive beamforming can separate the relatively slowly changed waveform delay information required from wideband RF signals, upon which a self-contained beamforming system is implemented with a low-speed baseband. By introducing vector RF multipliers in the frontend of the present invention, the amplitude and phase of RF signals are simultaneously controlled by the real and imaginary parts of complex numbers, such that beamforming algorithms derived in complex domain can be directly applied without any form of transformation. By doing so, the massive use of conventional T/R modules and high¬ speed baseband devices can be avoided, thus simplifying the realization and decreasing the cost of wideband digital beamforming systems for use in low cost, power efficient beamforming applications.
