| description | In this paper, a TE<sub>340</sub>-mode substrate-integrated cavity (SIC) excited 2 x 2 slot antenna subarray with two TE<sub>210</sub>-mode SICs' loading is presented at 140 GHz in low-temperature co-fired ceramic. By using the TE<sub>340</sub>-mode SIC, the number of vias used in the feeding network and the area of the feeding network can be reduced compared to the feeding network composed of conventional TE<sub>10</sub>/TE<sub>20</sub>-mode SIW power dividers. The proposed simplified and miniaturized high-order mode SIC-based feeding network leads to lower transmission loss and fabrication cost and reduces the fabrication difficulty. Each pair of radiating slots is loaded by a TE<sub>210</sub>-mode SIC to improve the impedance bandwidth and the gain performance. For the proof of concept, an 8 x 8 antenna array is further designed and measured. The measured impedance bandwidth of the proposed 8 x 8 antenna array is 10.7% from 130.3 to 145 GHz for |S<sub>11</sub>| ≤ -10 dB. The measured peak gain is 20.5 dBi. The measured radiation efficiency is 59.2%. |
