Abstract
A compact multiple-frequency Z-type Inverted-F antenna includes a dielectric substrate having a horizontal axis and a vertical axis perpendicular to the horizontal axis. A feed point is disposed along the horizontal axis on a first side of the vertical axis and a ground strip is disposed along the horizontal axis on a second side of the vertical axis opposite the feed point. A plurality of wedge-shaped radiating traces is arranged symmetrically with respect to the horizontal axis and disposed on the first side of the vertical axis. A plurality of wedge-shaped ground traces symmetrical to the plurality of radiating traces with respect to the vertical axis are disposed on the second side of the vertical axis.

A planar multiple-frequency antenna comprising:
- a dielectric substrate having a horizontal axis and a vertical axis perpendicular to the horizontal axis;
- a feed point disposed along the horizontal axis on a first side of the vertical axis;
- a ground strip disposed along the horizontal axis on a second side of the vertical axis opposite the feed point;
- and
- a plurality of wedge-shaped radiating traces arranged symmetrically with respect to the horizontal axis disposed on the first side of the vertical axis, a narrowest end of each radiating trace being nearest the feed point.
