GLASS ANTENNA SYSTEM FOR MOBILE TELEPHONE SET

摘要

PURPOSE: To provide a small sized glass antenna system for mobile telephone set with high sensitivity that receives a radio wave of two UHF bands in an excellent way. CONSTITUTION: A perpendicular from a feeding point A is used for a symmetrical axis, and a projection being upwards having a prescribed angle θ/2 around the symmetrical axis is formed with two line segments R with a prescribed length extended upward in the vicinity of the feeding point and with a line segment of an optional shape connecting tips of the two line segments. Then a planar radiation pattern 3 and a rectangular grounding pattern 4 having two sides H, L of prescribed lengths are formed symmetrically on a window pane 2 with respect to the symmetrical axis.
