ABSTRACT:
A double loop antenna which is suitable for a window antenna of a motor vehicle. Two contiguous loop conductors are formed on an insulation plane such as a window glass of the vehicle. A power feed point is provided at a contact portion of the loops. A reactance element conductor is coupled to each of said loop conductors, so that antenna impedance at the feed point becomes the only resistance component. The antenna has good transmission/reception characteristics in a UHF band for use of a vehicle telephone.
