“…We actually simulated the configuration investigated in that reference using Ansoft HFSS to find out what kind of bandwidth is obtainable, the bandwidth was very small (about 2%), far smaller than the bandwidth obtainable with the antenna proposed in this paper which exceeds 17%. Bandwidth enhancement techniques published in the literature for high dielectric constant DRAs include two or more stacked DRAs [15,16], coplanar parasitic DRAs [17,18], and inclusion of air gaps inside DRAs [19]. Such techniques require additional DRA elements increasing the size of the overall antenna or involve a more complicated geometry than the simple technique presented in this paper.…”

Abstract-This paper presents a novel broadband, low-profile dielectric resonator antenna using relatively low dielectric constant substrate material. The rectangular DRA is fed with a stepped microstrip feed to ensure efficient coupling. Bandwidths in excess of 17% are obtained. In addition, the paper investigates methods to miniaturize the antenna using metallic strips or patches. Substantial size reduction is demonstrated while maintaining a reasonable bandwidth. Simulations as well as experimental results are presented.

“…The benefit of dielectric resonators [4] in feeding systems requires accurate knowledge to stackle the resonators and components.

Abstract-Hybrid double frequency antennas are in huge requirement because of fast advancement of the recent wireless communications towards the body area networks applications. Therefore in this paper, a compact hybrid dielectric resonator antenna with a slot sustained by a microstrip line that is feasible for wireless body area network is investigated. In this model, the dielectric resonator performs the functions of an effective radiator along with the feeding structure and the slot in the ground plane. By varying the structural parameters, the antenna is built to oscillate at two different frequencies; one is from the dielectric resonator antenna (DRA) and the other from the slot. The structure has a dielectric resonator with the resonant frequency of 2.4 GHz (Industrial, Scientific and Medical) and a parasitic slot with a resonant frequency of 403 MHz (Medical Implantable Communication Service). The physical and geometrical parameters of these resonators are resonating to attain the required performance parameters. In order to the performance of the investigated antenna, functional parameters such as return loss, bandwidth, voltage standing wave ratio (VSWR), and radiation pattern are intended by the simulation of the structure with high frequency structure simulator (HFSS).

I. INTRODUCTIONThe DRA antenna is a very attractive alternative for applications at wireless communications. The different types DRAs such as cylindrical, rectangular, and hemispherical shapes [2]- [10] have been presented in literature. Cylindrical and rectangular dielectric resonator antennas are having attractive features over the triangular and hemi sphere shapes. A new dual band hybrid structure [2] to achieve dual frequency operation for WBAN applications is proposed. The proposed structure can be considered as the combination of DRA and other radiating resonator, such as a slot resonator [3]. These two elements are tightly stacked together and resonate at two different frequencies. The resonant modes corresponding to each resonant frequency is different from each other. Their radiation patterns have different performance for WBAN applications.The use of dielectric resonators [4] in feeding circuits requires accurate knowledge to couple the resonators and circuits. In order to match the DR to the feed line and to excite the desired mode in the resonator, the most common feeding technique is the aperture-coupled [5] arrangement. However, the resonant feeding structure adopted in these reported designs, such as microstrip-fed aperture-coupled, co-axial probe coupling, co planar slot feed and CPW-fed slot arrangement offers more flexibility and is directly compatible with different mounting surfaces. In this letter, in order to avoid via holes, the microstrip feed line is proposed [6]. The microstrip line [11] printed on the same substrate excites a dielectric resonator (DR) that could be placed directly over the feed line. The advantage of microstrip feed is easy to fabricate, simple to match by controlling the inset feed position, low spurious radiation and easy to model.To demonstrate the idea, the proposed hybrid dual-band antenna [7] is designed for wireless body area networks. It consists of upper (2.4 GHz) and lower (403 MHz) frequencies of the dual-band antennas [8] are primarily controlled by the DRA and slot respectively. The designed dual-band antenna has the maximum radiation directed toward the inside of the human body in the medical implantable communication service (MICS) [18]-[20]band in order to collect vital information from the human body [9], and directed toward the outside in the industrial, scientific and medical (ISM) band to transmit that information to a monitoring system. This design has the advantage of small size, simple structure and can achieve dual frequency operation with different radiation patterns.
