CPC H01Q 3/36 (2013.01) [H01F 21/02 (2013.01)] | 20 Claims |
1. A radar device, comprising:
an antenna array;
a transceiver coupled to the antenna array;
an antenna controller adapted to steer radiation beams from the antenna array; and
a phase shift device, comprising:
a variable inductor element configured to toggle between a first inductance state and a second inductance state in response to a first control bit value; and
a plurality of variable capacitor elements coupled to the variable inductor element and configured to toggle between a first capacitance state and a second capacitance state in response to a second control bit value different from the first control bit value,
wherein the variable inductor element and the plurality of variable capacitor elements collectively produce a first phase shift using the first inductance state and the first capacitance state and collectively produce a second phase shift using the second inductance state and the second capacitance state, wherein a target phase shift is produced from a difference between the first phase shift and the second phase shift.
