Dual-band dipole antenna
First Claim
1. A dual-band dipole antenna, adapted to be disposed on a dielectric substrate, comprising:
- two substantially rectangular radiating metallic sheets, symmetrically disposed on two sides of the dielectric substrate with respect to the central line thereof, thereby forming two arms of the dual-band dipole antenna, wherein each of the substantially rectangular radiating metallic sheets further has a feeding point disposed opposite to the other feeding point for transmitting signals; and
a slit extending from one edge of the substantially rectangular radiating metallic sheet in the direction of the feeding point to the interior thereof so that a longer path and a shorter one are formed on the substantially rectangular radiating metallic sheet, wherein the longer path serves to generate a first (lower frequency) operating mode of the dual-band dipole antenna, and the shorter path serves to generate a second (higher frequency) operating mode thereof; and
a coaxial transmission line having a core conductor and an external ground conductor which are respectively connected to the feeding points.

Abstract
A dual-band dipole antenna, which is adapted to be disposed on a dielectric substrate, comprises two substantially rectangular radiating metallic sheets and a coaxial transmission line. The substantially rectangular radiating metallic sheets are symmetrically disposed on two sides of the dielectric substrate with respect to the central line thereof, wherein each of the radiating metallic sheets further has a feeding point and a slit. One feeding point is disposed opposite to the other feeding point, and the slit extends from one edge of the substantially rectangular radiating metallic sheet to the interior thereof in the direction of the feeding point so that a longer path and a shorter one are formed on the substantially rectangular radiating metallic sheet, wherein the longer path serves to generate a first (lower frequency) operating mode of the dual-band dipole antenna, and the shorter path serves to generate a second (higher frequency) operating mode thereof. The coaxial transmission line has a core conductor and an external ground conductor which are respectively connected to the feeding points.
