“…Therefore, a relatively larger dielectric resonator is used for this DRA design, and a higher order mode is excited to enhance the electrical size of the antenna at mm W frequency. The advantages of higher order mode excitation are 2-fold, i.e., increase in the antenna electrical size in comparison with the antenna fundamental mode and increase in the antenna gain by a simple design through excitation of higher order mode. , The simulations of mm W antenna were carried out using time domain finite element solver of computer simulation technology (CST) studio suite 2021. Radiation performance of the DRA was tested in a near field microwave anechoic chamber.…”

Driven by the unrelenting perpetual demand of unparalleled network speed and capacity, millimeter wave (mm W) communication stands as an unequivocal pinnacle for 5G technology, compelling the imperative deployment of cutting-edge, highperformance antennas. In the vanguard of antenna innovation, this research introduces a mm W dielectric resonator antenna (DRA) distinguished by its state-of-the-art high quality factor temperature stable composite dielectric ceramic 0.3MgTiO 3 − 0.6Mg 2 TiO 4 −0.1(Ca 0.7 La 0.3 )(Ti 0.7 Al 0.3 )O 3 (MT-CLTA). Astoundingly, MT-CLTA composite ceramic prepared by the solid state reaction method at sintering temperature of 1230 °C showcased remarkable microwave dielectric properties characterized by optimal permittivity (ε r ) ≈ 18.0, high quality factor (Q × f) ≈ 51,700@14.47 GHz, and temperature coefficient of resonant frequency (TCF) ≈ −4.6 ppm/°C. At mm W frequencies, small size of DRA may pose challenges for precise fabrication. Therefore, larger DRA is designed with higher-order TE δ31 radiation mode of rectangular RDRA, excited using an aperture-coupled microstrip line feed structure to increase its electrical size at mm W frequency. RDRA demonstrates excellent radiation performance with a resonance frequency of 27.60, 1.22 GHz impedance bandwidth, measured realized gain of 6.55 dBi, and maximum radiation efficiency of 97%. Embodying virtues of high-quality factor, high gain, and temperature stability, this innovation boldly signals its application potential for 5G mm W communication.

“…Meanwhile, the authors of [9] presented a top-loaded modified Alford loop CP DRA with CP frequencies of 1.937, 2.45, and 3.51 GHz. In [17], a single-feed high-order triple-band CP was produced by using a 2-layer DRA with different permittivity, whereas in [20], CP was generated by using double stub strip on the DRA. The methods mentioned above did produce triple CP, but the AR bandwidth was small.…”

This paper proposes a new dielectric resonator antenna (DRA) design that can generate circularly polarized (CP) triple-band signals. A tripleband CP DRA antenna fed by a probe feed system is achieved with metal strips structure on side of DRA structure. The design start with conventional rectangular DRA with F shaped metal strips on DRA structure alongside the feed. Then, the F metal strip is enhanced by extending the length of the metal strip to obtain wider impedance bandwidth. Further improvement on the antenna performance is observed by improvised the conventional DRA structure. The method of removing part of DRA bottom resulted to higher antenna gain with triple band CP. The primary features of the proposed DRA include wide impedance matching bandwidth (BW) and broadband circular polarization (CP). The primary features of the proposed DRA include wide impedance matching bandwidth (BW) and broadband circular polarization (CP). The CP BW values recorded by the proposed antenna were ∼
