ABSTRACT:
A single-layer adaptive plane array antenna device includes a variable reactance circuit including a variable capacitance circuit controlled by bias voltage, a resonating folded line bias circuit having an AC grounding node for supplying the bias voltage to the variable capacitance circuit, for transmitting the bias voltage to the variable capacitance circuit including a thin line interconnecting spacer for transmitting the bias voltage to the variable capacitance circuit side and first and second open folded stubs each of which is connected to the thin line interconnecting spacer, each of which is also disposed in parallel with a longitudinal direction of each other in a prescribed small gap with the thin-line interconnecting spacer, each of which has a folded shape and each of which functions as an inductance element and a capacitance element respectively for separating the variable capacitance circuit from the AC grounding node.
