Abstract :
In this paper, a novel dual-band hybrid antenna consists of a CPW-fed inverted-L monopole and a high permittivity rectangular dielectric resonator (DR) is presented. The inverted-L monopole simultaneously acts as an effective radiator and the feeding structure of the DR. The high permittivity rectangular DR can be efficiently excited if its dimensions and the relative position on the monopole are properly determined. By connecting the monopole and the DR in parallel, a dual-band hybrid antenna with compact size is achieved. A prototype antenna has been designed to satisfy the IEEE 802.11 WLAN standards
