  • Abstract
    This paper deals with the in-band RCS reduction of dielectric resonator antenna (DRA). Scattered fields by the DRA are initially separated into two parts: structural mode and antenna mode. By properly choosing the termination impedance at the antenna´s port, the re-radiated field from the antenna mode can effectively cancel the scattered field by the structural mode, resulting in a substantial reduction of the in-band RCS of the antenna. Numerical results are provided to demonstrate the procedures and the effectiveness of the cancellation concept.
