“…The SIW slot antenna arrays, which are one of the basic types of aperture antenna arrays, have extensively been studied both analytically and experimentally [28][29][30][31][32]. By employing balun characteristics of the SIW with intrinsic CM suppression, as a design example, a 1 × 4 single-row differential SIW slot antenna array with differential transition structure using paired microstrips is shown in Fig.…”

In this study, the differential substrate integrated waveguide (SIW) slot antenna array is proposed with intrinsic common‐mode (CM) rejection. Through field analysis, it is found that the SIW is a natural differential transmission line which can only transmit differential signal due to the characteristics of hybrid electromagnetic boundary perfect electrical conductor and perfect magnetic conductor. Hence, it can also be seen as a natural balun with intrinsic CM suppression. Thus, a compact 1 × 4 differential SIW slot antenna array with high CM rejection can be designed using the differential microstrip transition structure which has little conversion between differential‐mode (DM) and CM. For the design of differential SIW passive device, the DM equivalent half circuit is a single‐ended SIW device with height halved. Further, the 4 × 4 differential SIW antenna array with high CM rejection can be designed with a T‐shaped differential SIW four‐way power divider. The 1 × 4 and 4 × 4 differential SIW antenna arrays are fabricated and good agreements between the simulated and measured results demonstrate the validity of proposed configurations.

“…This type of antenna is also the most commonly used mm-wave antenna array in engineering practice. With the development of substrate integrated circuits, the substrate integrated waveguide (SIW) slot arrays have been widely studied because of their compact and lightweight structure [ 11 , 12 , 13 ]. In addition, grid antenna arrays printed on single-layer substrate are also widely used in mm-wave radar [ 14 , 15 , 16 , 17 ], as these antennas have the advantages of wide impedance bandwidth, high gain, and high polarization purity.…”

“…The radiation elements used in the proposed array have been introduced in detail in [ 26 , 27 ]. It should be pointed out that the proposed array uses the element designed in our previous work, just like the single-layer mm-wave arrays [ 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 ] use patch, slot, or grid elements. This work has been preliminary introduced in our conference paper [ 28 ].…”

A single-layer ±45° dual-polarized directional array antenna for millimeter wave (mm-wave) applications is designed in this communication. Based on the theory of orthogonal circularly polarized (CP) wave multiplexing, two ports of a series-fed dual CP array are fed with equal amplitudes, and the array can radiate a linearly polarized wave with ±45° polarization orientations through the adjustment of the feeding phase difference. As the two ports of the series-fed array are simultaneously excited, the antenna can achieve directional radiation. In addition, the cross-polarization level of the array can be effectively suppressed by placing two series-fed arrays side by side. A prototype of the designed array antenna operating at 30 GHz is fabricated and measured; the working bandwidth of the proposed antenna is approximately 3.5%. Owing to its simple structure and directional radiation, the proposed antenna array is a competitive candidate for mm-wave applications.

“…In many practical applications, antenna arrays often require low sidelobe. For example, the PSLL of uniform Substrate Integrated Waveguide slot antenna arrays is close to 13.60 -dB, but in common radar system, the lower PSLL is often required [2]. Therefore, it is necessary to research an effective method to depress the PSLL of antenna arrays.…”
