ABSTRACT:
An antenna unit which has a high gain and a wide bandwidth at a low resonance frequency thereof. The antenna unit comprises an antenna body and a power radiation electrode. The antenna body comprises a rectangular-prism-like substrate comprising a dielectric material, whose major ingredients are e.g., barium oxide, aluminum oxide and silica. A power supply conductor is provided in the substrate and is made of copper or copper alloy and is wound in a spiral in the direction of height of the substrate. A power supply terminal for applying a voltage to the power supply conductor is provided on a surface of the substrate. Further, a power radiation electrode, which comprises, e.g., a nearly rectangular metallic plate made of copper, copper alloy or aluminum, is provided on the surface of the substrate of the antenna body. This power radiation electrode is electrically isolated from the power supply conductor.
