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.

“…With the development of wireless communication systems, DRAs with dual-band performance have been widely investigated [3][4][5]. Hybrid DRA [6][7][8][9][10][11][12] technology is a viable candidate for realizing dual-band operation. A direct approach to designing a hybrid DRA is to introduce an extra slot resonator [9].…”

Abstract-In this paper, a cross-slot-coupled dual-band circularly polarized (CP) hybrid dielectric resonator antenna (DRA) is presented. The design concept is based on using a cross-slot as both a feeding structure of the DRA and an effective radiator. Full wave simulation is used to verify the proposed design concept in this paper. A prototype antenna is designed, fabricated, and measured. Good agreement is obtained between the simulated and measured results.

“…The need of the high-data rate, in the recent communication devices, has forced the researchers to enhance the small antenna bandwidth. In the literature, several studies have been reported to achieve wide-bandwidth enhancement of DRAs suitable for wideband applications, as using stacked segment dielectric resonators (DRs) [1], stacked-embedded DRs [2], hybrid DRA [3], and special geometries of DR, such as conical [4], tetrahedral [5], elliptical [6], stair [7], H-shaped [8], and P-shaped [9]. Using these techniques, an impedance bandwidth range of 30-70% has been achieved.…”

Abstract-In this paper, a numerical study of a new ultra wideband (UWB) dielectric resonator antenna (DRA) is presented. The proposed structure consists of two stacked dielectric resonators excited by rectangular patch and operated from 3 GHz to 11 GHz (an impedance bandwidth of 115%), covering the full UWB spectrum. The analysis is carried out using the Finite Difference Time Domain (FDTD) method and two commercial electromagnetic simulators. The numerical results are given and compared in terms of reflection coefficients, radiation pattern and gain. The computed FDTD results are in good agreement with those of simulations.
