1. An electronic device, comprising:
a substrate;
a plurality of varactors arranged on the substrate; wherein each of the varactors is defined with a capacitor-voltage characteristic curve, in which each of the varactors is provided with a plurality of capacitance values in response to a plurality of varactor voltage values in a respective manner;
a memory element defined with one or more lookup tables, wherein the capacitance values and the varactor voltage values of the capacitor-voltage characteristic curve are recorded in the lookup table(s);
a driving unit outputting a plurality of voltage signals respectively to the varactors, and each of the voltage signals respectively provided with one of the varactor voltage values; and
a plurality of antenna elements arranged on the substrate and electrically connected to the varactors; each of the antenna elements being provided with various phase values in response to the capacitance values of a corresponding one of the varactors;
wherein a selective one of the varactor voltage values in response to the required one of the capacitance values of a corresponding one of the varactors is found out from one or ones of the lookup table(s) and delivered by the driving unit; whereby the antenna elements are together enabled to form a wave beam with a characteristic wavefront in accordance with the capacitance values.
