A dielectric resonator based line stripe miniaturized ultra‐wideband antenna for fifth‐generation applications

Abstract

Summary This work presents an original dielectric resonator based line stripe miniature ultra‐wideband (UWB) antenna for 5G applications. The length, width, and height of the designed antenna are 23, 15, and 1.605 mm, respectively. The projected antenna prototype is composed of a simple line structure‐based modified scattered patch and a rectangular ground plane consisting of a saw tooth orientation in the upper end. A number of rectangular resonators are placed on both sides of the patch and ground to optimize the desired results. This technique ensures the lower operating band and made a significant improvement of efficiency without compromising the antenna size. The proposed design obtained the range of frequency bandwidth from 3.55 to 4.2 GHz under the −10‐dB scale, which covers the lower fifth‐generation (5G) communication band offered by Federal Communications Commission (FCC). The moderate gain and more than 80% radiation efficiency at a resonant point with strong fidelity factor confirms the usability and lower signal distortion of the antenna. The design offers an omnidirectional radiation pattern with 90° elevated directivity for cross polarization. This proposed design is compact in size and can be integrated into limited space around microwave circuitry with low manufacturing cost. The performance parameters like operating bandwidth, antenna size, and area of application, dielectric constant, fractional bandwidth, and omnidirectional radiation pattern were proposed as a suitable candidate for 5G application.

Machine learning-based technique for resonance and directivity prediction of UMTS LTE band quasi Yagi antenna

“…According to CST's calculations, the proposed design has a peak gain of 6.9 dBi, as opposed to the 5.6 dBi, 6.46 dBi, 6.73 dBi, 5.02 dBi, 4.27 dBi, 4.3 dBi, and 5 dBi reported by the references. Reference articles [9] , [10] , [12] , [13] , [14] report radiation efficiencies of 82.4%, 70%, 80%, 73%, and 96%, respectively; however, 89.9% is measured in CST for the proposed Yagi antenna. The investigations based on machine learning are not employed in the references that have been listed above; even so, they are extensively used in the design that has been presented.…”

“…Table 1 shows a comparison of many ongoing parallel activities. Reference papers [9] , [10] , [11] , [12] , [13] , [14] report reflection coefficients of -35.58 dB, -27 dB, -25.02 dB, -35 dB, -29 dB, and -32 dB, respectively; nevertheless, in the suggested Yagi antenna, it is observed as -38.4 dB in CST. According to CST's calculations, the proposed design has a peak gain of 6.9 dBi, as opposed to the 5.6 dBi, 6.46 dBi, 6.73 dBi, 5.02 dBi, 4.27 dBi, 4.3 dBi, and 5 dBi reported by the references.…”

Ultra wideband (UWB) dielectric resonator antenna using fractal‐inspired feeding mechanism

“…For small‐range 4G/5G UWB wireless communication 27 and vehicular and cellular communication repeaters, a compact fractal patch‐fed DRA with an impedance bandwidth of 3.38–10.71 GHz and 7.23 dBi maximum gain is presented in this research report. A rectangular‐shaped dielectric resonator makes up the DRA (RDR).…”

The Antennas of Next Generations

“…This name was therefore particularly appropriate for the radiating wire structures deployed by the pioneers of radiotelegraphy at the end of the 19th century. Subsequently, the structures evolved and diversified considerably to take account of both the discovery of new terrestrial propagation modes and the constant technological progress towards higher frequencies [1]. The aim of this paper is to investigate new generation antennas by highlighting the different antenna designs that have been studied, their modelling methods, structure, size, operating frequencies and the different application areas for future use.…”
