1. A dielectric antenna for a high frequency wireless communication apparatus, said antenna comprising:
- a dielectric substrate;
a conductive meander line layer formed on the dielectric substrate;
a conductive feed line layer formed on the dielectric substrate, said conductive feed line layer being of a greater line width than the meander line layer; and
a conductive taper layer connecting the conductive meander line layer to the conductive feed line layer, said conductive taper layer having an edge slanting at an angle γ
from an adjoining edge of the conductive feed line layer as measured in a direction toward the conductive meander line layer, said conductive taper layer connecting the meander line layer to the conductive feed line layer having a line width which continuously decreases from the line width of the conductive feed line layer toward the conductive meander line layer.

Abstract
A dielectric antenna is provided for a high frequency wireless communication apparatus. The antenna includes a dielectric substrate and a conductive meander line layer formed on the dielectric substrate. A conductive feed line layer, having a greater line width than the width of the meander line layer, is also formed on the dielectric substrate. A conductive taper layer connects the conductive meander line layer to the conductive feed line layer. An edge of the conductive taper layer slants at an angle from an adjacent edge of the conductive feed line layer in a direction toward the conductive meander line layer.
