    ABSTRACT: In this paper, a novel wideband dielectric resonator antenna (DRA) structure is proposed. A low-profile DR with high permittivity is placed in close proximity to a microstrip-fed inverted-L monopole and there is no ground plane underneath the DR. The inverted-L monopole simultaneously acts as an effective radiator and the feeding structure of the DR. By carefully tuning the position of the resonator, DR can be electromagnetically coupled to the monopole and also works as an efficient radiator. Dual resonances of the two radiators are merged together to achieve a wideband operation

    ABSTRACT: A compact planar ultra-wideband ring monopole antenna with a band-notch feature is presented. The band-notch characteristic is achieved by embedding a quarter-wavelength tuning stub in the circular ring monopole. The notched band is controllable by adjusting the length of the tuning stub. The measured antenna radiation patterns show good omnidirectional performance across the operation bandwidth. © 2005 Wiley Periodicals, Inc.

    ABSTRACT: A novel hybrid antenna structure that combines a rectangular dielectric resonator and a CPW-fed slot with tuning stub is proposed. The proposed antenna is designed to resonate at the lower (2.4 GHz) and upper (5.3 GHz) 802.11 WLAN frequency bands, respectively. Comparisons between the simulation and measurement results confirm the good properties exhibited by the proposed antenna. © 2005 Wiley Periodicals, Inc.
