Abstract
An antenna element comprises an insulating substrate; a first conductor layer formed continuously on an upper surface, a bottom surface and at least one side surface of the insulating substrate; a strip gap consisting of a portion in which a conductor layer is not formed on an upper surface and/or a side surface of the insulating substrate; and a second strip conductor layer formed in the slot or in an insulated extension connected to the strip gap thereby being electrically insulated from the first conductor layer, the second conductor layer being electrically connected to a feeder. The first conductor layer formed on an upper surface of the insulating substrate is divided by at least one slit gap extending substantially in perpendicular to the direction of electric current at a position separated from the strip gap.
