“…In terms of the feeding technique and bandwidth, [11][12][13]24] show that such a class of antennas provides narrow bandwidth when a 90-degree coaxial to SIW transition is used. On the contrary, the waveguide transition implemented in [29,30] shows a wider bandwidth. The value followed by '*' indicates that the specific measurement result is not mentioned in the text.…”

Substrate integrated waveguide (SIW) technology that combines 3D and 2D structures has been successfully utilized due to its notable advantages, including in its application to H-plane horn antennas. As this type of antenna is commonly constructed on thin substrates, the E-plane radiation pattern is always wide, thereby limiting the achievable gain performance. In this work, we propose an approach that incorporates 3D printed horns on a prefabricated SIW H-plane horn antenna to successfully narrow the E-plane radiation pattern, thereby improving the gain performance. The proposed E-plane horn is designed at the aperture of the original H-plane horn, providing a smooth and continuous wave transition from the thin substrate to the end-fire direction. This approach improves the directional radiation performance significantly and reduces fabrication time and associated difficulties as the parasitic structures are simply attached to the SIW horn, without the requirement of redesigning or refabricating the original antenna. From 20 to 25 GHz, an optimized prototype shows excellent performance. At 22.7 GHz, it exhibits 35° and 33° for the E- and H-plane half-power beamwidths (HPBWs), with corresponding side-lobe levels (SLLs) of −23 dB and −15 dB. The present research reveals that the proposed design presents high feasibility and a reduced demand for high-precision manufacturing processes at a lower cost, concomitantly providing an effective means to further improve on the radiation characteristics.

“…The initial design is a traditional dielectric taper, and the lower-end limitation for s 11 < − 10 dB is 19.5 GHz. To further extend the lower-end limitation, a two wedges matching section [3] which has the identical width and length with the traditional taper is used.…”

“…In recent years, with the rapid development of wireless communication technology as well as the arrival of 5G communication era, the high data throughput is urgently demanded, thus, the end-fire antennas operated in millimetre-waveband with wideband and high directivity have drawn tremendous attention. The main types of mm-wave end-fire antennas are as follows: microstrip array antenna [1], slot antenna [2], SIW horn antenna [3], lens antenna [4] and dielectric-rod antenna [5]. Among them, the dielectric antenna has relatively high aperture efficiency.…”

In this study, a broadband and high gain dielectric‐rod end‐fire antenna are proposed for applications on both the K and Ka bands. By employing the double‐ridged waveguide (DRW) feeding structure which is composed of a coaxial line to tapered DRW transition, a parabolic tapered DRW, and a parabolic‐tapered flared parallel waveguide section, the impedance bandwidth of this proposed antenna is broadened to 84.5%. The dielectric‐rod with the double circular truncated cone structure acted as the main radiator of the proposed antenna is adopted to achieve higher gains and lower side‐lobe levels as compared to the traditional circular cone dielectric‐rod, while the four‐wedges structure inserted in the waveguide is developed as the matching section of the dielectric‐rod to further improve the impedance matching. The measured results show that this antenna can be operated in 17.9–44.1 GHz, and the measured gain changes from 9.9 to 15.5 dBi. Moreover, the radiation patterns are demonstrated with observed end‐fire characteristic in the overall operating band.

“…Several research works have been undertaken on the design of SIW directional and omnidirectional horn antennas. In [15][16][17][18][19][20][21][22], the detailed descriptions of the designs of directional SIW horn antennas have been presented. The inclusion of a thin substrate in the designs presented in [15][16][17][18][19][20] results in higher side lobe level (SLL), lower gain, and lower front to back ratio (FBR).…”

A compact substrate integrated folded waveguide (SIFW) H-plane horn antenna array with simultaneous omnidirectional and directional radiation characteristics for potential utilization to high-speed wireless communication is presented in this article. The realization of the proposed design has been accomplished by placing the apertures of nine exponentially tapered SIFW H-plane horns towards the circumference of a cylindrical substrate with an angular separation of 40 • between the horns. Every horn flaring includes a column of three slots. Centre probe feed technique has been used to excite the antenna. The radiation of the field by the horn apertures and through the slots of the horns flaring, respectively, results in an omnidirectional and a directional radiation pattern at 13.8 GHz and 18.42 GHz, with the gain of 7 dBi and 10.92 dBi. The proposed antenna has performed well and is in good agreement between simulation and measurement. The dimension of the antenna is 37.3 mm (diameter) × 1 mm (height) (1.71λ 0 × 0.046λ 0 at 13.8 GHz and 2.29λ 0 × 0.061λ 0 at 18.42 GHz). SIFW technology makes low profile antenna. The proposed design can be a promising option to be used as a low-profile antenna for high-speed wireless communication.
