A DUAL ANTENNA STRUCTURE FOR THE SUPPRESSION OF THE REAR SIDE RADIATION

摘要

PURPOSE: A dual antenna structure for retaining rear side radiation is provided to design miniaturized antenna using a technique for estimating the amount of rear side radiation. CONSTITUTION: An antenna structure is composed of a ground plane(G1), a front side dielectric(D1), a front side radiator(R1), a rear side dielectric(D2), a rear side radiator(R2), a power supplying network(100). A dielectric with relative dielectric constant is arranged between the front side radiator and the ground plane or between the rear side radiator and the ground plane. The dielectric is capable of being replaced with an air layer, the relative dielectric constant of which is 1.
