Abstract
One embodiment relates to a radar system. In one embodiment, an automotive radar system comprises a power amplifier configured to provide first and second anti-phase transmission signals to respective first and second differential couplers which are individually connected to respective first and second transceiving antennas. A first portion of the first anti-phase transmission signal is coupled to the first antenna and a second portion of the first anti-phase transmission signal is coupled to a third transceiving antenna by way of a third differential coupler. A first portion of the second anti-phase transmission signal is coupled to the second antenna and a second portion of the second anti-phase transmission signal is coupled to the third antenna by way of the third differential coupler. Configured in this manner, the radar system is operable to transmit and receive from the multiple antennas with high efficiency, while maintaining low-cost and reduced overall size.
