“…In recent years, the shared-aperture antenna technique which can easily realize a dual-band antenna or array with a large frequency ratio has become a hot topic. [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23] This technique provides an effective way to reduce the antenna size, thus, miniaturizing the entire communication system. The reported shared-aperture antennas can be summarized into the following two categories, that is, using large-frequency-ratio antenna units 6 or combining multiple resonance modes to form a shared-aperture antenna, such as Fabry-Perot resonator antenna (FPRA) + waveguide resonator antenna (WRA), 7 FPRA + dielectric resonator antenna (DRA), 8 and patch antenna + DRA.…”

A tri‐band shared‐aperture antenna operating at both the sub‐6G and millimeter‐wave bands is proposed for 5G/B5G communications. It is small in size owing to the structure sharing technique. Four longitudinal slots are etched on the top of a substrate integrated waveguide (SIW), forming a millimeter‐wave antenna operating at 28 GHz. Meanwhile, the outer conductor of the entire SIW is used to realize a monopole antenna that can operate at 3.5 and 4.9 GHz, respectively. The structure reuse efficiency of the monopole radiating area is about 80%. A tri‐band microstrip line to SIW transition is proposed to excite different transmission modes in the sub‐6G and millimeter‐wave bands, thus, realizing the proposed large frequency ratio tri‐band antenna with a single shared port. A prototype of the proposed antenna is fabricated and measured, and the measured results agree well with the simulated ones, validating the correctness of this design.

“…Dual-band four-port MIMO antenna can expand system capacity and realize multi-mode communication. To minimize the unwanted mutual coupling, various isolation techniques have been reported in recent years [3][4][5][6][7][8][9][10][11][12][13][14]. The rectangle slots of the defected ground plane and two rectangular microstrip lines are employed to decrease the mutual coupling in [3].…”

A quad-port antenna array operating in 3.5 GHz band (3.4–3.6 GHz) and 5 GHz band (4.8–5 GHz) for fifth-generation (5G) smartphone applications is presented in this paper. The single antenna element consists of an L-shaped strip, a parasitic rectangle strip, and a modified Z-shaped strip. To reserve space for 2G/3G/4G antennas, the quad-port antenna array is printed along the two long frames of the smartphone. The evolution design and the analysis of the optimal parameters of a single antenna element are derived to investigate the principle of the antenna. The prototype of the presented antenna is tested and the measured results agree well with the simulation. The measured total efficiency is better than 70% and the isolation is larger than 16.5 dB.

This work presents a dual-band (3.5/26 GHz) shared-aperture antenna with high aperture reuse ratio and high isolation. The proposed 26-GHz 4 Â 4 substrate integrated waveguide (SIW) cavity-backed slot array antenna consists of four hybrid TE 130 -TE 310 -mode SIW cavities, which can simplify the design of feeding network. The radiating slots are unequally offset and inductance windows are added for good impedance matching. The entire structure of the 4 Â 4 slot array antenna also functions as an equivalent TM 10 -mode patch antenna at 3.5 GHz. The resonant frequency of the patch is fine-tuned by inserting an air gap instead of enlarging the patch length, thus ensuring high aperture reuse ratio. To enhance channel isolation, the patch is designed with a bandpass filtering response centered at 3.5 GHz by introducing a stub-loaded resonator feeding structure. For demonstration, a prototype of the proposed dual-band antenna was fabricated and measured. The measured results show that the proposed antenna achieves excellent dual-band performance, and its aperture reuse ratio and channel isolation are as high as 87.5% and 62 dB, respectively.
