“…The absence of miniaturization techniques, particularly at low frequencies, makes the integration impractical for portable devices. Antenna miniaturization techniques for DRAs include C-shaped slotted ground plane [5], use of copper sheet on DRA face [6], metalized upper and lower part of rectangular DRA [7], and stacking of dielectric resonators [8]. All these techniques though successfully reduce the antenna size, the 3D DRA geometry yet poses severe constraints for integration into compact hand-held devices.…”

A compact hybrid antenna structure with frequency reconfiguration capabilities is presented in this article. The proposed design employs a combination of a rectangular DR element and a coupling slot on the structure's ground plane (GP). The slot shifts the fundamental DRA mode by introducing a slow wave effect and its resonant behavior helps to achieve an omnidirectional pattern at low frequencies. The slot is loaded with a series of PIN diode switches whose ON/OFF combinations alter the effective slot length. Slot loading with PIN diodes results in frequency reconfiguration of the proposed structure with a large tuning range of 76.2% (between 1.73 and 3.86 GHz). A parametric analysis was performed to investigate the effects of slot length, width, and position on the reflection coefficients of the proposed structure. A prototype of the proposed design was fabricated and results were measured. The measured results show a close agreement with the simulated ones. The proposed design is suitable for DCS 1800 MHz, PCS 1900 MHZ, UMTS, LTE 2500-2700 MHz, and Wimax 3.5 GHz.

A novel printed S-shaped monopole antenna for tri-band Wireless local area network (WLAN) operation is presented. The antenna consists of two meander radiating strips leading to generate two separate resonant modes where the first mode is for the 2.4GHz-band and the second mode is for the 5.2/5.8GHz-band operation. The proposed antenna has a measured impedance bandwidths of 2.24-2.64 GHz and 4.95-6GHz, and owns good radiation characteristics across the impedance bandwidths, with a compact size of 28xl5xl.6mm3 including the ground plane.

“…Compact cylindrical sector DRA has been developed with a 75% reduction in volume compared to conventional CDRA with the support of fractional modes and allowance of dual frequency/dual feed operation [10][11][12]. The volume of the sectorized antenna can be reduced by using metalized faces of the DRA [11,13].…”

A two element half split Cylindrical Dielectric Resonator Antenna (CDRA) with probe feed is proposed for wideband monopole-type radiation pattern. The proposed antenna has been designed and fabricated. The input and radiation characteristics of the proposed antenna have been determined through the Ansoft HFSS simulation software. Simulation results are compared with measured results and found good agreement. The input characteristics of the proposed antenna have been also compared with half split CDRA. The proposed antenna provides wide bandwidth (&66%) and monopole type radiation pattern with low cross polarization level for wireless application.
