DRA’s are used for 5G communications of large bandwidth at sub 6GHz and millimeter to Terahertz. The channel capacity can achieve a very high data rate i.e. C=Blog2(1+SNR) where C is the channel capacity and B is the bandwidth of the channel. The cylindrical resonator antenna operating in hybrid HEM11⸹ mode. In this paper a cylindrical dielectric resonator antenna(CDRA) with frequency range (2-6GHz).The cylindrical dielectric resonator with radius r=10mm and height h=10mm. the CDRA material is alumina ceramic with a permittivity of εDRA is 9.9 and the resonant frequency is fr=4GHz. The substrate will be is Rogers RT 5880 with εr=2.2 and tan⸹=0.0009, the thickness is 1.52mm. The CDRA is excited about the microstrip line. so the cdra is coupled electromagnetically by this microstrip line and below the substrate, we have a ground plane with annealed alumina so we have no radiation or low below the substrate all the radiation is top of the CDRA. The proposed antenna is simulated using CST microwave studio software and the designed antenna will operate for 5G applications and we can consider massive MIMO antenna array configurations. This design analyses the parameters of CDRA.

In this paper, a simple conical-shaped dielectric resonator antenna operating in HEM11δmode is presented for X-band wireless applications. A rectangular slot with a running microstrip line is used for excitation purpose. By placing a FR-4 based superstrate at 7 mm height from the ground FR-4 substrate and incorporating a set of modified ground plane on either side of the feed line, gain is improved by 42.85% and bandwidth by 68.92%, simultaneously. A prototype of designed antenna is fabricated and characterized. The measured results are found to be good in matching with the simulated ones.

This paper proposes a novel wideband circularly polarized (CP) dielectric resonator antenna (DRA) loaded with strips. The CP DRA comprises a circular DR, two pairs of driven L-like DR strips with different lengths, and a square ground-plane. To couple the electromagnetic energy to circular DR, an orthogonal cross-slot is used, and a stepped microstrip-line is also used to adjust the impedance matching. Influenced by the concept of deformed DR, two pairs of L-like DR strips of different lengths are inserted into the circular DR as part of the driven element to excite a new axial ratio (AR) resonant point. An antenna prototype is simulated, manufactured, and measured to validate the unique design. The measured results show that the designed antenna has broadband characteristic with a −10 dB IBW of 54% (1.91–3.32 GHz) and 3 dB ARBW of 42.1% (2.10–3.22 GHz).

A double recurrence cylindrical resonator arrangement along meander opening space inclined with microstrip feed is prescribed to deliver desired recurrence performance. An outlining structure involves cylindrical dielectric arrangement and meander opening space. A meander space resonator originates from the ground plane. Through adapted prototype variables, the cylindrical resonator performs at the subsidiary frequency (2.36 GHz) as well as the opening frame functions at lowering channel (915 MHz), while utilizing the FR 4-substrat and Both resonators have two discrete radiation descriptions. Referencing the ultimate goal of accomplishing the quality of the prescribed display, for example acceptable parameters, reflection coefficient and transmission range. The modeled framework demonstrates that the reflection coefficient <-10 dB and can be exhibited throughout the functioning ranges with enormous impedance and enhanced radiation illustration. The organized reception apparatus arrangement has little in estimate, less weight, lessened cost and satisfactory isolation. The intended model is sensible for WBAN applications.

A novel pattern reconfigurable antenna concept utilizing rectangular dielectric resonator antenna (DRA) placed over dielectric substrate backed by a ground plane is presented. A dual strip excitation scheme is utilized and both excitation strips are connected together by means of a 50 Ω microstrip feed network placed over the substrate. The four vertical metallic parasitic strips are placed at corner of DRA each having a corresponding ground pad to provide a short/open circuit between the parasitic strip and antenna ground plane, through which a shift of90°in antenna radiation pattern in elevation plane is achieved. A fractional bandwidth of approximately 40% at center frequency of 1.6 GHz is achieved. The DRA peak realized gain in whole frequency band of operation is found to be above 4 dB. The antenna configuration along with simulation and measured results are presented.

Measurement Results

In this paper, a microstrip-fed U-shaped dielectric resonator antenna (DRA) is simulated, designed, and fabricated. This antenna, in its simple configuration, operates from 5.45 to 10.8 GHz. To enhance its impedance bandwidth, the ground plane is first modified, which leads to an extended bandwidth from 4 to 10.8 GHz. Then by inserting a rectangular metallic patch inside the U-shaped DRA, the bandwidth is increased more to achieve an operating band from 2.65 to 10.9 GHz. To validate these results, an experimental antenna prototype is fabricated and measured. The obtained measurement results show that the proposed antenna can provide an ultra-wide bandwidth and a symmetric bidirectional radiation patterns. With these features, the proposed antenna is suitable for ultra-wideband applications.
