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.
