“…Tang et al extended the design of differential dielectric resonator antennas for dual-band and dual-polarized operation [82], [83] and for integration with filters [84]. More interestingly, they developed a substrate-integrated differential cavity-backed dual-polarized dielectric resonator antenna with a wide bandwidth, low profile, high isolation, and improved gain [85].…”

Driven by the great demand for highly integrated wireless system-on-chip and system-in-package devices, there has recently been increasing interest in the research and development of differential antennas. Many studies on the design, analysis, and measurement of differential antennas have been published. This paper presents an overview of the fundamentals and applications of differential antennas. First, it compares differential to balanced and single-ended to unbalanced antennas and explains why the new terms (differential and single-ended antennas) should be adopted instead of the old terms (balanced and unbalanced antennas). Second, it addresses the quantitative relationship between a differential antenna and its single-ended counterpart, which is important and useful because the properties of either the differential or single-ended antenna can be determined from the other with a known solution. Third, it describes how differential antennas can be measured, with a special emphasis on the balun method. Fourth, it classifies differential antennas into wire, slot, microstrip, printed, and dielectric resonator antennas to better present their suitability and functionality. Fifth, it provides application examples of differential antennas from simple discrete wire to sophisticated microstrip designs. Finally, it is argued that the old paradigms of lower gains and bulkier sizes of differential antennas as compared to single-ended antennas do not always hold true; for instance, differential microstrip patch antennas can possess comparable or even smaller sizes and higher gain values than single-ended microstrip patch antennas.

In this paper, a moon-shaped aperture-coupled ring-shaped dielectric resonator antenna (DRA) is suggested, realized, and tested. The L-shaped microstrip line is designed to stimulate the aperture. Vital characteristics of the proposed radiator are as follows: (a) Broadband DRA with dual-frequency circular polarized (CP) response is realized by the mixture of HEM X 11δ and HEM Y 11δ mode inring DRA; (b) wide impedance bandwidth is attained with the help of dropping the effective permittivity of radiating structure by converting cylindrical shape into a ring shape. To test the practical feasibility, the proposed antenna design is fabricated and tested inside the anechoic chamber. Practical outcomes confirm that the proposed antenna works over the frequency range of 2.44-3.66 GHz along with supporting dual CP waves within the operating range, i.e., 2.44-2.64 and 3.4-3.65 GHz respectively. Broadsided (θ = 0 0 and ϕ = 0 0 ) RHCP radiation pattern makes the proposed antenna design applicable for IEEE 802.15.4 wireless sensor network (2.5 GHz) and WiMAX (3.5 GHz).

“…A differential-fed antenna can avoid this problem because it allows lower offset and higher linearity [ 14 , 15 ]. Hence, differential-fed DRA [ 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 ] with excellent performance has great potential for high frequency on-chip communication applications. Recently, some efforts have been devoted to the design of the differential dual-polarized DRAs [ 27 , 28 , 29 , 30 , 31 ].…”

A broadband differential-fed dual-polarized hollow cylindrical dielectric resonator antenna (DRA) is proposed in this article. It makes use of the HEM111, HEM113, and HEM115 modes of the cylindrical hollow DRA. The proposed DRA is simply fed by two pairs of conducting strips and each pair of strips is provided with the out-of-phase signals. After introducing four disconnected air holes into the DRA, a broadband characteristic is achieved, with little effect on the antenna gain of its higher-order modes. To verify this idea, frosted K9-glass is applied to fabricate the hollow cylindrical DRA. The differential S-parameters, radiation patterns, and antenna gain of the DRA are studied. It is found that the proposed differential-fed dual-polarized DRA is able to provide a broad differential impedance bandwidth of ~68% and a high differential-port isolation better than ~46 dB. Moreover, symmetrical broadside radiation patterns are observed across the whole operating band. The proposed DRA covers the frequency bands including the 5G-n77 (3.4–4.2 GHz), 5G-n79 (4.4–5.0 GHz), WLAN-5.2 GHz (5.15–5.35 GHz), and WLAN-5.8 GHz (5.725–5.825 GHz), which can be used for 5G communications.
