Broadband chip antenna
First Claim
1. A chip antenna comprising:
- a dielectric block including a first surface, a second surface being opposite to the first surface, and side surfaces being disposed between the first and second surfaces;
a first electrode pattern extending from a feeding port area formed on the first surface to the second surface via one side surface adjacent to the feeding port area; and
a second electrode pattern extending from a ground port area formed on the first surface to the second surface via the other side surface adjacent to the ground port area, wherein a first slit is formed as an open area for connecting two opposite sides of the first surface so as to electrically separate the feeding port area of the first electrode pattern from the ground port area of the second electrode pattern, and a second slit is formed in the same direction as the first slit as another open area for connecting two opposite sides of the second surface so as to form an electromagnetic coupling between the first and second electrode patterns.

Abstract
Disclosed is a chip antenna including first and second electrode patterns serving as radiation elements as well as a power-feeding element and a ground element, respectively. The first and second electrode patterns are separated from each other by first and second slits. The dimension of the electrode patterns is increased by extending the width of the first electrode pattern to correspond to the length of the first slit, and the first and second electrode patterns form the successive resonant length via the second slit. The chip antenna of the present invention has a broad usable frequency band. This broadband chip antenna of the present invention may be achieved as a super broadband chip antenna with multi-band characteristics. The frequency characteristics of the chip antenna may be easily adjusted by varying the width of the slit and the length of the electrode pattern or by forming a supplementary slit or an open area.

17. A chip antenna comprising:
-
a dielectric block including a upper surface, a lower surface, and side surfaces being disposed between the upper and lower surfaces;
an electrode formed on the entire surfaces of the upper and lower surface, and two opposite side surfaces; and
slits for connecting opposite sides of two side surfaces without the electrode and dividing the electrode to a first electrode pattern and a second electrode pattern, each of the slits being formed on the upper and lower surfaces of the dielectric block, wherein the slit formed on the lower surface of the dielectric block at least separates a feeding port area from a ground port area, and the other slit formed on the upper surface of the dielectric block connects the first electrode pattern to the second electrode patterns by an EM(Electro-Magnetic) coupling.
