摘要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 20×10.8 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.
