Summary:A cost-effective solution for Beamforming in miniaturized S-Band Radar applications is presented in this paper. To achieve this, Beamforming Front End consisting of 4 channels powered and controlled by a Power and Control Unit (PCU) is developed. A linear 1 x 4 sub-array is designed as the primary radiator for each channel. The proposed RF chain consists of Mixer, Phase Shifter and Power Amplifier in each channel. The beamsteering mechanism is demonstrated for various steer angles. The cost of the designed module is compared with popular Analog Beamforming (ABF) Integrated Circuits (ICs) in market and found to be drastically reduced.
