“…Various types of conformal ultrawideband (UWB) antennas have been studied in the literature, including the Vivaldi antenna, 1 the transverse electromagnetic (TEM) horn antenna, 2,3 and the H-plane horn antenna. [4][5][6][7][8][9][10] Compared with the conformal log-periodic monopole antenna and the conformal TEM horn antenna, the conformal H-plane horn antenna has a smoother surface, making it more suitable for conformal applications with an accessible aerodynamic structure. However, the H-plane horn antenna has a limited impedance bandwidth due to the cut-off frequency of the waveguide and high-order modes.…”

An ultrawideband 3D printed aperture‐shared conformal dual‐horn antenna that is mounted on a cylindrical metal surface is proposed. The antenna system consists of an H‐plane horn antenna working at 0.5–5.5 GHz, namely Antenna A, an H‐plane horn antenna working at 5.5–16 GHz, namely Antenna B, and a diplexer. To validate the proposed aperture‐shared antenna, a prototype is 3D printed with surface metallization. A diplexer is used to connect Antenna A and Antenna B. Measured results show a 32:1 impedance bandwidth for the dual‐horn antenna system with |S11| < −6.8 dB. Good radiation patterns are also obtained for most of the bandwidth.

To achieve multi‐function integration and independent performance regulation of microwave and millimetre‐wave (mm‐Wave) shared‐aperture antennas, a design method based on embedded structure fusion is proposed. In the Sub‐6G band, a high‐order mode annular‐ring patch antenna is designed. To transform the non‐broadside characteristics, the current distribution of TM31 and TM12 modes is reconstructed by slotting in the centre of the patch. Additionally, the electric field distribution is modified by loading shorting pins to achieve beam broadening. In the 5G mm‐Wave band, a four‐element high‐gain substrate integrated waveguide (SIW) slotted cavity backed antenna array with low‐sidelobe characteristics is obtained using the element interleaving technique. The SIW slotted cavity backed antenna array is integrated into the central area of the annular‐ring patch to achieve aperture‐sharing fusion. Experimental results demonstrate that the antenna operates in the Sub‐6G dual‐band of 2.1–2.2 GHz and 5.2–5.4 GHz, respectively. Furthermore, the widest half‐power beamwidth measured in these two bands is 126° and 140°. In the mm‐Wave band, the operating bandwidth is 26.5–29.5 GHz, with a gain of up to 18.8 dBi. Notably, the performance of different bands does not impact the other, and the measured isolation exceeds 40 dB. Furthermore, the antenna profile is only 0.008 λ0. Therefore, an ultra‐low‐profile microwave and mm‐Wave shared‐aperture antenna with multi‐function integration and independent performance control is realised, which has great potential for application in 5G intelligent connected vehicle communications.
