“…Published works have shown that, the CDRA is the most widely used technology although the rectangular dielectric resonator antenna (RDRA) has shown several advantages. The reason behind that attraction is the simple mode structure of the CDRA as compared to RDRA (larger number of edges in the RDRA lead to more complicated mode [8]. The main advantage of CDRA for high gain applications is that, it is more directional as compared to rectangular and annular shaped DRAs [9].…”

In this paper, a compact two-element cylindrical dielectric resonator antenna (CDRA) array with corporate feeding is proposed for X-band applications. The dielectric resonator antenna (DRA) array is excited by a microstrip feeder using an efficient aperture-coupled method. The designed array antenna is analyzed using a CST microwave studio. The fabricated sample of the proposed CDRA antenna array showed bandwidth extending from 10.42GHz to 12.84GHz (20.8%). The achieved array gain has a maximum of 9.29dB i at frequency of 10.7GHz. This is about 2.06dB i enhancement of the gain in comparison with a single pellet CDRA. The size of the whole antenna structure is about 5050mm 2 .

“…Several different shapes of DRAs have been proposed in the literatures i.e., cylindrical [2], rectangular [3] and triangular [4]. Among these shapes, cylindrical dielectric resonator antenna (CDRA) is widely used, due to its simple field structure as compared to rectangular DRA [5], and it is directional as compared to the rectangular and circular DRAs (i.e., rectangular and circular DRAs are bidirectional) [6]. The CDRA is characterized by its height h, radius a and permittivity ε r as shown in Figure 1(a).…”

In this paper, the tuning technique of 3-elements cylindrical dielectric resonator antenna (CDRA) array for wireless LAN 802.11 a/b/g standard applications is studied experimentally. The rectangular shaped aperture slots are used to excite the first and last radiating element. The aperture slots etched on the ground plane are excited by using the 50Ω microstrip transmission line. The electromagnetic coupling technique is used to excite the middle radiating element to enhance the antenna bandwidth as well as gain. The effects of changing the dimensions of slot width on the resonance frequency are also analyzed using a CST microwave studio. The simulated and measured results have successfully given the resonance at 2.45 and 5.0 GHz. The 2-D and 3-D radiation patterns of the proposed dual band antenna are addressed in this paper.
