Document Type and Number:
Japanese Patent JP4764688
Kind Code:
B2
Abstract:
A triplate planar slot antenna formed by laying a ground plate, a lower layer side dielectric layer, a lower layer side copper-clad film substrate, an upper layer side dielectric layer, a slot plate and an upper layer side copper-clad film substrate sequentially from the bottom side, wherein a lower layer side copper foil piece is secured to the surface of a lower layer side insulating film by a joining technique not using adhesive, and an upper layer side copper foil piece is secured to the surface of an upper layer side insulating film by a joining technique not using adhesive. In a state where the copper foil pieces are removed, each insulating film has a dielectric constant in the range of 2.0-4.0, a tan delta in the range of 0.001-0.01, and a thickness of 25 mum or less.
