“…There are many millimeter wave antennas equipped with different design features. A circularly polarized cylindrical cavity-backed substrate embedded waveguide resonator for millimeter wave applications has been proposed by Tewari et al [17]. Two symmetrical rectangular slots are diagonally set up on the top metal plane of the cavity, and the feed site is designed for better impedance matching.…”

This article proposes a Ka‐band substrate integrated waveguide (SIW) quasi‐Yagi array antenna with the advantages of thinness, compactness, wide bandwidth, and higher gain. Analyzing the microstrip‐to‐SIW transition structure to confirm that the designed structure provides the best performance, the optimum reflectance coefficient bandwidth can be obtained. With the optimized rectangular etched slot structure at the antenna end, the impedance matching can be tuned to improve the bandwidth. The designed array antenna is fabricated and measured for verification. The substrate is based on Al2O3 ceramic and the antenna size is 23.3 mm 13 mm 0.5 mm. The measurement results indicate that the antenna achieves an impedance bandwidth of 13.59% below −10dB, with an average gain of approximately 7 dBi and a peak gain of 7.4 dBi in 28.1–32.2 GHz. Therefore, the 1*2 antenna proposed in this paper has the advantages of compact and planar structure, easy fabrication, and easy integration into RF circuits, which is very suitable for Ka‐Band applications.

A planar miniaturized rectangular substrate integrated waveguide (SIW) cavity resonator with an array of patches is presented, which enhances the overall gain of antenna at the K band. The aperture‐coupled feeding is provided from SIW rectangular cavity resonator to reduce radiation losses as in microstrip feeding at a higher frequency. The resonating fields from the cavity excite an array of patches on the substrate. This is further replicated uniformly to design a 4 × 4 element multiple input multiple output (MIMO) antenna. The overall antenna dimension is 2λ × 3.1λ × 0.07λ, where λ is the operating wavelength. The compact structure configuration provides a high peak gain of 13.98 dBi resonating at 19.97 GHz in a broadside direction. An isolation of −17.53 dB is achieved by inserting metal pins. The envelope correlation coefficient of 0.0001 and total active reflection coefficient of −10 dB show characteristics of a high‐performing MIMO antenna. The antenna structure is simulated using HFSS ver. 2022, measured using Anritsu Vector Network Analyzer and Anechoic Chamber, the simulated and measured results are in good concurrence. The antenna is suitable for satellite communication, short‐range wireless applications in IoT, and radar.
