“…Various types of antenna element have been reported to build the integrated antenna array with LTCC technology, mainly including microstrip patch antenna [5][6][7], metamaterialbased antenna [8,9], and substrate integrated cavity antenna [10][11][12][13][14][15][16]. The microstrip patch antenna is the most popular radiator candidate for integrated systems because of its simple structure and excellent performance.…”

A broadband substrate integrated cavity (SIC) antenna array based on high-order mode is proposed for low-temperature cofired ceramic (LTCC) integrated systems in W-band. To improve the gain of antenna element, a large SIC is adopted to work in high-order mode, which also avoid using excessive vias and reduce the process complexity. Two parasitic patches are loaded on the high-order mode SIC to remove the reverse E-field in the open aperture, leading to a high-gain broadside radiation. The high-order-mode SIC antenna element is fed by high-order TE 20 -mode substrate integrated waveguide (SIW), rather than regular TE 10 -mode SIW. The simplified feeding network with TE 20 -mode SIW is also designed with wideband performance, further enhancing the fabrication robustness of antenna array. To validate the proposed high-order mode-based antenna element and feeding network, a W-band 2 � 4 antenna array is designed as an example using LTCC technology. The measured return loss is better than 10 dB from 81.1 to 98.1 GHz (19% bandwidth) with a maximum gain of 18.3 dB at 94 GHz. The proposed antenna array has great potential in millimetre-wave and terahertz LTCC integrated applications.

“…However, using the high mode will cause the problem of narrow bandwidth, and it is difficult to balance the bandwidth and efficiency of the antenna. Moreover, in recent years, some new technologies, such as low-temperature cofired ceramic (LTCC), have been applied to low-profile antenna design [24,25]. A 4 � 4 high-gain TM211 mode SIC array using multilayered LTCC technology is introduced in Ref.…”

Based on substrate-integrated waveguide (SIW) antenna technology, a compact high-gain slot array is proposed in this paper. The proposed antenna is suitable for designing circular aperture and large-scale array in W-band. A method of dividing the array into multiple sections is proposed, which provides a solution for widening the bandwidth of large-scale SIW slot arrays. The proposed antenna is composed of the backside waveguide feeding network and the upper SIW array. A novel method of loading biased metal vias on SIW is proposed to realize unequal power distribution. And it makes the antenna array to be compact, low-cost, and easy to manufacture. An antenna prototype is fabricated and measured. The measured bandwidth of the antenna array is 92.2-96.2 GHz within |S 11 |<−10 dB, and the measured maximum gain is 31.8 dBi at 94 GHz, which correspond to the radiation efficiency and aperture efficiency of 27.5% and 15.7%, respectively. The proposed antenna is an excellent candidate for millimetre-wave radar applications.

This article presents a W‐band three‐layer reflectarray antenna that can be easily fabricated using printed circuit board (PCB) process. The proposed reflectarray element is composed of substrate integrated waveguide (SIW) structure and slot‐coupled patch. By controlling the length of SIW in each element, the compensation phases required for the reflectarray to generate focused beam at in‐band frequencies are realized. However, at the out‐of‐band frequencies, the elements fail to provide the required compensation phases as the incident electromagnetic wave cannot couple to the SIW. Thus, filtering performance is realized. A circular aperture prototype reflectarray comprising of 5024 elements are employed to yield a high‐gain narrow beam. The measured results show that the proposed reflectarray antenna attains a peak gain of 40.5 dB at 94 GHz with aperture efficiency of 41.3%, and out‐of‐band suppression higher than 22 dB.
