Title:
24-GHZ LOW-COST CONTINUOUS BEAM STEERING PHASED ARRAY FOR INDOOR SMART RADAR AND METHODS RELATING THERETO
Document Type and Number:
WIPO Patent Application WO/2017/176816
Kind Code:
A3
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.
