ABSTRACT:
This invention provides a vehicle window glass antenna arranged in a space left below defogging heater strips for transmission and reception of ultrashort waves used for mobile phones and/or personal radios. The antenna section has a primary antenna which is a combination of a plurality of elongate elements connected to each other so as to form a closed plane figure having one to four vertexes each of which is acutely angled and pointed upward and becomes an upper end of the primary antenna. The plurality of elongate elements includes a single horizontally elongate element which becomes the bottom side of the plane figure. The antenna includes a secondary antenna section which is essentially a horizontally elongate element positioned below the primary antenna section. The antenna feeder is a coaxial cable, and the primary and secondary antenna sections are connected with the inner and outer conductors of the coaxial cable, respectively.
