“…In [10], a high-frequency magneto-electric dipole antenna was placed above a low-frequency patch antenna. The second category is the embedded structure, in which the high-frequency antenna is embedded into the low-frequency antenna [14][15][16][17][18][19][20][21][22]. For instance, in [17], the MMW DRA was embedded in the MW patch antenna in a co-planar form.…”

In this article, a microwave (MW)/millimeter wave (MMW) aperture-sharing antenna is proposed. The antenna is constructed using two orthogonal columns of grounded vias from a 3.5 GHz slot-loaded half-mode substrate-integrated waveguide (HMSIW) antenna. These vias are reused to create two sets of 1 × 4 MMW substrate-integrated dielectric resonator antenna (SIDRA) arrays. With this proposed partial structure reuse strategy, the MW antenna and MMW arrays can be integrated in a shared-aperture manner, improving space utilization and enabling dual-polarized beam steering capability in the MMW band, which is highly desirable for multiple-input multipleoutput (MIMO) applications. The integrated antenna prototype was manufactured and measured for verification. The 3.5 GHz antenna has a relative bandwidth of 3.4% (3.44–3.56 GHz) with a peak antenna gain of 5.34 dBi, and the 28 GHz antenna arrays cover the frequency range of 26.5–29.8 GHz (11.8%) and attain a measured peak antenna gain of 11.0 dBi. Specifically, the 28 GHz antenna arrays can realize dual-polarization and ±45° beam steering capability. The dual-band antenna has a very compact structure, and it is applicable for 5G mobile communication terminals.

“…The antenna in reference [25] integrates 5G WIFI and 60-GHz Wi-Gig applications, and can realize beam scanning. Recently, Ren et al designed a highfrequency ratio Vivaldi antenna system that integrates 5G Sub 6GHz and 5G millimeter wave applications [26]. Millimeter-wave operating bands were achieved by etching small Vivaldi antenna arrays on the wings of conventional Vivaldi antennas operating at 5G Sub-6GHz.…”

In this paper, we design a novel antenna with dual-band and multi-radiation modes by integrating the two metasurface binary array antennas (MBAAs) into the antipodal Vivaldi antenna (AVA). Metasurface binary array antenna 1 (MBAA-1) and metasurface binary array antenna 2 (MBAA-2) are symmetrically embedded on two radiation patches of AVA. When AVA is excited, vertical down radiation can be achieved. When MBAA-1 or MBAA-2 is excited, horizontal forward or backward radiation can be achieved. The simulated results show that AVA and MBAAs have the -10 dB return loss bandwidths of 163.6% and 9.3% and the realized gain of 5.5–8.1 dBi and 8.0–10.0 dBi cover the Ground Penetrating Radar (GPR) band (0.6–6.0 GHz) and the 5-GHz WIFI band (4.9–5.9 GHz), respectively. The test results are in good agreement with the simulated results. The proposed antenna realizes the integrated design of 5-GHz WIFI and GPR antennas, which can be applied to the antenna system design of intelligent robots and UAVs, and contribute to the integration development of wireless communication and radar in the future.
