<p>The invention provides a small dielectric antenna capable of easily changing the frequency band and bandwidth and unlikely to deteriorate its performance. The dielectric antenna includes feeder terminals attached to the upper surface, lower surface or a side of a flat dielectric plate (1). An antenna electrode is formed on the upper surface of or within the dielectric plate (1). The feeder terminals and the antenna electrode are connected on the upper surface of, or within, or through the side of the dielectric plate. The antenna electrodes (2, 2') are formed in a spiral, and they are connected by unbalanced feeders.</p> |
