Abstract

A novel asymmetric unilateral monopole CPW dual-band antenna is screen-printed on the high dielectric Aluminum Oxide ceramic substrate by the screen-printing technique in this letter. Owing to the high dielectric constant ceramic substrate and asymmetric unilateral structure are used, the size of the antenna can be minimized to only 20 Ã— 10.8 mm². The proposed antennas reveal near omni-directional radiation patterns, and the optimum measured bandwidth are 11% (at 2.455 GHz) and 11.6% (at 5.425 GHz), the optimum measured return loss are -21.4 dB (at 2.455 GHz) and -19.1 dB (at 5.425 GHz), respectively.
