Antenna mounting printed-circuit board
First Claim
1. An antenna mounting printed-circuit board for incorporation into equipment having at least a communication function, said printed-circuit board adapted to mount various modules thereon, comprising:
- a chip-like antenna element formed into a shape having a rectangular horizontal cross section and having an open end formed of at least two antenna conductors separated from each, said antenna element adapted for mounting on the printed-circuit board;
a ground utilized by one or more of said various modules and arranged so as to surround a surrounding area of at least three of four sides to form the rectangular horizontal cross section in the antenna element, andwherein the antenna element is mounted on a substantially central position of an arbitrarily selected side of the antenna mounting printed-circuit board.

Abstract
A chip-like printed antenna in which an open end is formed by at least two antenna conductors separated from each other is mounted on a printed-circuit board. A ground required by one or plural other modules is disposed and mounted on the printed-circuit board so as to surround a remaining area of a surrounding area of the printed antenna except a partial area as indicated by oblique line parts. By this, in the printed-circuit board , a radiation electric field does not come to have a dipole mode, but is formed into a balloon shape and is radiated in one direction as indicated by a broken line.
