Abstract

A miniature dielectric loaded monopole antenna fed by coplanar waveguide (CPW) is proposed for WLAN applications in the 2.4/5-GHz bands. The dielectric material is a cylindrical block of ceramic with a 22 permittivity. The back side of the ceramic material with a simplified open-end tuning stub is also proposed. The prototype has been designed and fabricated and found to have bandwidths of 8% and 35.3% at the resonant frequencies of 2.48 and 5.60GHz, respectively, and the radiation patterns measured at resonance frequencies are very close to omnidirectional in the H-plane. The characteristics of the proposed antenna has been investigated using simulation software HFSS and experimental results. The measured and simulated results show excellent agreement
