“…In addition, in References 12 and 13 SMSH is used to increase the gain to more than 10 dBi, but the bandwidth and gain of the above antennas are still smaller than the antenna proposed in this article. Compared with this paper, the DRA proposed in Reference 11 obtains a larger operating bandwidth (44%). However, the maximum gain of the DRA is only 6.8 dBi, and the gain curve fluctuates greatly, with the minimum gain of 2.3 dBi.…”

“…In order to improve directivity, a large floor or metal wall is required, but this usually greatly increases the size of the antenna. The DRA proposed in the literature 11 obtains a fractional bandwidth of 44% (3.02–4.73 GHz). The maximum gain is 6.8 dBi, but the gain curve fluctuates greatly around 4 GHz, where the gain is only about 2.5 dBi.…”

A design method of metal coaxial resonator antenna (MCRA) is proposed in this article. According to this method, a broadband MCRA working in highorder modes is designed. The proposed antenna fuses two frequency bands of different high-order mode pairs, thus achieving 30% fractional bandwidth. The measured operating frequency band of the antenna is 2.95-4.1 GHz, in which the gain is more than 8.5 dBi. In addition, in order to improve the gain, a lowprofile dielectric lens (DL) is designed. With the DL loaded, the À10 dB S11 band shifts to 3.1-4.1 GHz, and the gain of is more than 11 dBi. A close agreement has been achieved between the measured and simulated results.

“…Moreover, these techniques destroy the shapes and aesthetics of the DRAs. The third technique is to excite multiple modes of the DRA [20,21,22]. In [21], a wideband DRA is proposed by merging the adjacent bands corresponding to TE 121 and TE 211 modes.…”

An aesthetic wideband dielectric resonator antenna (DRA) based on the Minkowski fractal slot is firstly presented. The proposed DRA consists of a glass dielectric resonator (DR) with the laser engraving pattern, the ground with the Minkowski fractal slot, the fork-shaped microstrip line, and the substrate. By employing the Minkowski fractal slot, the TE 111 mode of the DR and an additional hybrid mode are excited to realize the wideband characteristics. A parametric study is performed to analyze the wideband DRA performance. The simulated results show the hybrid mode and TE 111 mode can be controlled independently. To achieve the aesthetics of the DRA, a school badge is engraved inside the glass DR. Finally, the proposed DRA is fabricated and measured. A wide impedance bandwidth of 38.4% and the peak gain of 6.5 dB for S 11 < -10 dB are achieved.

The Y3Al5O12 transparent dielectric ceramic is of permittivity εr ≈10.53 and Q × f ≈ 95219 GHz (Q = quality factor = 1/tanδ and f = 7.37 GHz), which is excellent to be applied for the dielectric resonator antenna (DRA). A dual‐band filtering DRA (FDRA) is proposed to verify the special dielectric properties of Y3Al5O12 transparent dielectric ceramic. The FDRA is designed by seamlessly integrating a dual‐band DRA based on rectangular Y3Al5O12 transparent ceramic with a quadruple‐mode stub‐loaded loop resonator (SLLR). The DRA operates at the TE111y and TE113y modes excited by a common coupling slot. The SLLR serves as a feeding network, whereas the DRA works as a dual‐mode resonator as well as the radiating element. The reflection coefficient, realized gain, and the radiation pattern of the dual‐band FDRA are examined. It is observed that the proposed FDRA operates at 3.42 and 5.28 GHz with impedance bandwidths of 5.8% and 4.0%, respectively, which are used for the fifth‐generation (5G) network and applications. Good dual‐band filtering performance is achieved while realizing radiation efficiency above 84.1% and 85.4% at two bands.
