Loss mechanism of the SISL and the experimental verifications

Abstract: In this study, the loss mechanism of substrate integrated suspended line (SISL) is investigated and the experimental verification is given. The strategy to reduce the total circuit losses, including the radiation loss, the conductor loss, and the dielectric loss based on SISL platform, is investigated. For the three cases in the form of uniform transmission lines, their characteristic impedance, phase constant, and attenuation constant are simulated and compared. The influences caused by the height of the air … Show more

“…Besides, the conductor loss and the dielectric loss of the proposed DBBPF can be improved by the further optimization of the circuit structure and the patterned substrate. 18 The simulated and measured results are wellagreed, which validates the design concepts of the proposed filters.…”

“…The loss of SISL in three cases is simulated in Wang and Ma. 14 However, the three cases have different impedance due to maintaining the same linewidth, and the contribution of dielectric loss and conductor loss has not been individually analyzed.…”

“…Substrate integrated suspended line (SISL) [13][14][15][16] circuits feature low loss using FR4 substrates because almost all the electromagnetic (EM) field is distributed in the lossless air rather than the lossy substrates. 12,13 Using FR4 substrate to design high-frequency circuits will have great advantages in terms of cost, especially in mass production.…”

“…FR4 substrate is widely used in board‐level circuits because of its low price, high mechanical stability and good insulation performance, 12 but it is difficult to be used in high‐frequency circuits due to its high loss tangent. Substrate integrated suspended line (SISL) 13‐16 circuits feature low loss using FR4 substrates because almost all the electromagnetic (EM) field is distributed in the lossless air rather than the lossy substrates 12,13 . Using FR4 substrate to design high‐frequency circuits will have great advantages in terms of cost, especially in mass production.…”
