Ultra-wideband planar antenna having frequency notch function
First Claim
1. A planar antenna manufactured by patterning a substrate consisting of a dielectric layer, and first and second conductive layers applied, respectively, to both opposite surfaces of the dielectric layer, comprising:
- a first slot formed in the first conductive layer for radiating electric waves;
a second slot formed in the first conductive layer for intercepting a particular frequency of the electric waves radiated by the first slot;
a power supply portion formed with the first conductive layer for supplying electric current to the first slot; and
a radiating element formed with the second conductive layer, which is excited by the electric waves radiated by the first slot, and radiates the electric waves.

Abstract
A planar antenna manufactured by patterning a substrate consisting of a dielectric layer, and first and second conductive layers applied, respectively, to both opposite surfaces of the dielectric layer. A first slot is formed in the first conductive layer for radiating electric waves. A second slot is formed in the first conductive layer for intercepting a particular frequency of the electric waves radiated by the first slot. A power supply portion is formed with the first conductive layer for supplying electric current to the first slot. A radiating element formed with the second conductive layer, which is excited by the electric waves radiated by the first slot, and radiates the electric waves.
