“…Concurrently, dielectric resonator antennas (DRAs) have emerged as a focal point of research interest owing to their intrinsic advantages, which include heightened radiation efficiency, expanded bandwidth, facile excitation, and compact form factors. Moreover, the absence of ohmic losses renders DRAs particularly appealing for applications in millimeter-wave (mmWave) and terahertz (THz) systems [ 5 , 6 , 7 ]. Consequently, many studies have explored the development of frequency, pattern, and polarization reconfigurable DRAs, as reported in [ 8 , 9 , 10 , 11 , 12 , 13 , 14 ], for example.…”

This paper introduces an innovative and cost-effective approach for developing a millimeter-wave (mmWave) frequency-reconfigurable dielectric resonator antenna (DRA), which has not been reported before. The antenna integrates two rectangular DRA elements, where each DRA is centrally fed via a slot. A strategically positioned PIN diode is employed to exert control over performance by modulating the ON–OFF states of the diode, thereby simplifying the design process and reducing losses. In the OFF state, the first DRA, RDRA-I, exclusively supports the TE311 resonance mode at 24.3 GHz, offering a 2.66% impedance bandwidth and achieving a maximum broadside gain of 9.2 dBi. Conversely, in the ON state, RDRA-I and RDRA-II concurrently operate in the TE513 resonance mode at 29.3 GHz, providing a 2.7% impedance bandwidth and yielding a high gain of up to 11.8 dBi. Experimental results substantiate that the proposed antenna presents an attractive solution for applications necessitating frequency-reconfigurable and high-performance mmWave antennas in 5G and Beyond 5G (B5G) communication systems.

“…In [18,19], initial designs of MIMO antenna using DRA, which combines advantages of both MIMO and DRA technology, were presented in 1983. In [20], recent MIMO DRAs have been reviewed comprehensively. Generally, adhesive or glue is used to stick the DRA on the substrate, which gives rise to performance degradation due to an extra layer of glue dielectric between DR and substrate.…”

In this dissemination, a glueless compact dual port dielectric resonator antenna (DRA) is proposed for X-band applications. A prototype has been fabricated with RT Duroid substrate and Eccostock (ϵr = 10)-made DRA. The ring shaped DRA is excited by aperture coupled feeds maintaining symmetry between both the ports. Four cylindrical copper rods with four strips have been used to fix the DRA on the substrate and provide additional mechanical stability. Eight copper strips are used to provide impedance matching and impedance bandwidth (IBW) widening. The measured IBW of dual port DRA is 10.5% (8.05–8.95 GHz) and maximum gain of radiator is 6.2 dBi. The proposed antenna becomes compact when the net volume of DRA is approximately 3.5 cm3 and the volume of the substrate is 2.88 cm3, with a surface area of 36 cm2 and operating in X-band, which finds applications in satellite communication, weather radar, synthetic aperture radar, and telemetry tracking and control.
