摘要： In the antenna device, a first insulating plate, a capacitive coupling portion of a tuning plate, a radio wave absorber, a grounding portion of the tuning plate folded back to the back side of the radio wave absorber, and a tuning coated plate provided with a metallic plated film formed on the surface thereof are sequentially stacked below an antenna element having a shape obtained by removing an arched portion from a copper circular plate. Power is supplied from a center conductor of a semi-rigid signal input member to a power feeding unit of the antenna element. An external conductor is held between the upper and lower conductive cushions. A grounding plate is conductive with the external conductor, to ground the grounding portion and the tuning coated plate.

摘要： A wideband antenna system includes a metal radiating portion, an aperture contact, a feed contact, an aperture tuner, an impedance tuner, a first switch, and a second switch. Two ends of the metal radiating portion respectively include a first contact and a second contact. The aperture contact is electrically connected to the metal radiating portion and is located between the first contact and the second contact. The feed contact is electrically connected to the metal radiating portion and is located between the first contact and the aperture contact. The aperture tuner is electrically connected to the aperture contact, and the impedance tuner is electrically connected to the feed contact. The first switch is electrically connected between the first contact and a zero-ohm resistor to selectively effect connection of the first contact to the zero-ohm resistor. The second switch is electrically connected between the first contact and the impedance.
