“…Table 2 provides a brief comparison between some related antennas and the proposed antenna. References [9] and [13] both have a wide bandwidth, but they do not have a filtering function. High dielectric constant DR is used in [19] to achieve a very low profile at the cost of reducing the antenna bandwidth.…”

To achieve a low-profile, wide-bandwidth, and highly selective design, this paper presents a substrate integrated suspended line (SISL) based broadband filtering dielectric resonator antenna (DRA) with the improvement of suppression level. The dielectric resonator is cylindrical and fed from the bottom by a microstrip-coupled slot. The dual head structure with the designed open stub can provide two radiation nulls on both sides of the passband for the filtering function and can excite three resonant modes (HEM11δ, HEM11δ, and TE131 mode) at different resonant frequencies to enlarge the impedance bandwidth of the proposed antenna. Then, adding a metal branch perpendicular to the feeder can offer a radiation null to eliminate the undesired resonances in the right stopband. Finally, the suppression level at high frequency is improved further by filling Sub2's cavity with FR4. A prototype has been manufactured and measured for demonstration. Measurement shows that the proposed antenna has a -10-dB impedance bandwidth of 32.9% (2.98-4.15 GHz), a flat gain within the passband, and the gain suppression level within the stopband exceeds 15.5 dB.INDEX TERMS Dielectric resonator antenna (DRA), filtering antenna, improvement of suppression level, substrate integrated suspended line (SISL), wideband.

“…Over the last few decades, dielectric resonator antenna (DRA) has been extensively studied due to their advantages of a high degree of design flexibility, high efficiency, and wide bandwidth [8][9][10][11][12][13]. And, some filtering DRAs that do not require additional filtering circuits have been studied [14][15][16][17][18][19].…”

“…In recent years, there has been more research on 5G antennas. The dual polarization antennas proposed in references [1] - [4], although their isolation and gain are not low, can only cover the N77 frequency band and cannot cover the N78 N79 frequency band. Reference [5] proposes a dual polarized dipole antenna with operating frequencies ranging from 3.18 to 5.19 GHz and a reflection coefficient greater than 15.…”

This paper proposes a miniaturized ± 45º dual-polarized antenna, which obtains a certain bandwidth by grooving in the dipole and digging out the circular plaque at the edge, adding parasitic branches and parasitic patches at the end of the dipole to obtain a wider bandwidth, using a W-type feed, which can obtain a wider bandwidth compared to the Y-type feed, and the results show that the antenna covers the three frequency bands (3.3-5GHz) of N77, N78 and N79. And the antenna in 3.29-5.0GHz S11 and S22 are less than -15, and the gain is not less than 8dBi, the isolation between the two ports is higher than 25dB, HPBW change range within 66±8°, the size is only 0.37λ*0.37λ

“…Until now, numerous dielectric antennas have been reported and can be generally divided into two categories. The first one is the classical dielectric resonator antenna (DRA), which has been widely used in many practical applications [1][2][3][4][5]. But in the design of a DRA, there is often a trade-off between the bandwidth and size owing to its resonant structure.…”

A kind of all‐dielectric circularly polarised (CP) loop antenna made of high‐permittivity material is proposed. The leaky‐wave radiation from a high‐permittivity dielectric waveguide is utilised here to support the operation of the proposed antenna. A non‐closed dielectric loop covering a three‐quarter circle is adopted to generate CP radiation and it is connected with the dielectric ground via one of bending ends to form an all‐in‐one structure of the antenna. The other end is also bent and vertical to the ground, but hanging in the air for probe feed. As two kinds of typical high‐permittivity dielectric materials, zirconia ceramic and pure water are used to implement the proposed design respectively. On one hand, an all‐ceramic CP loop antenna made of zirconia is proposed. And benefiting from the low loss and high melting point of zirconia, the proposed ceramic antenna has superiority in radiation efficiency and could adapt to a harsh environment. On the other hand, by using pure water and transparent container, a fully‐transparent CP water loop antenna can be obtained. Finally, a 3‐D printing technology is adopted in the manufacturing of ceramic structure and resin container. Measured results of both antennas demonstrate the validity of the proposed design.
