摘要: An antenna device having two resonance frequencies wherein radiating patches are respectively provided on one surface and the other of a dielectric plate which is disposed above ground with space interposed therebetween. A coupling control capacitor element connected between these elements plate, respectively. Capacitance selected such that current coupled from to supplied said via in opposite phase at patches.
