“…28,29) With the application of micromachining technology, micro-mechanical waveguide structures with frequencies of 100 ∼ 1000 GHz (0.3-3 mm wavelengths) can be easily produced on the silicon substrate. 30,31) Based on silicon-based MEMS technology, the parameters of the model can be changed by means of adjusting the thickness of the dielectric layer, the conductor width, the vertical height, and the gap width between the ground plane and the conductor. According to the design rules, the characteristic impedance is set close to 50 Ω.…”

In this paper, a waveguide with metal shielding and a three-dimensional extension component is proposed with frequencies up to 110 GHz. By increasing the relative area between the signal line and the ground plane vertically, the electromagnetic field is limited within the air-dielectric cavity. By embedding metal shielding strip arrays into silicon oxidation, conductor and dielectric losses can be reduced significantly. In addition, the algorithm which extracts the transmission characteristics of the waveguide based on the Z parameter matrix is implemented. Compared to the conventional coplanar waveguide (CPW) and CPW with metal shielding, the results demonstrate that the structure can achieve a large bandwidth with DC–110 GHz, while the transmission loss is 0.0765 dB mm−1 at 110 GHz, which is reduced by 19.7% and 9.9%, respectively. Moreover, the value of Q with the proposed structure can reach 37.528 at 110 GHz, which is increased by 92.7% and 37.7%, respectively.

“…A measured insertion loss of 0.70 dB and a return loss higher than 25 dB with a 3 dB fractional bandwidth of 50.4% at a central frequency of 2.62 GHz were obtained. A microstrip line filter with band stop characteristics is presented in [15]. The miniaturization was achieved with a meander structure.…”

Models of hybrid meander structures with additional shields are presented in this paper. The influence of additional shields and their grounding positions on the electromagnetic characteristics of the hybrid meander structures was investigated. Three-dimensional models were created and analyzed using the method of moments (MoM) in the Sonnet® and finite-difference time-domain (FDTD) method in CST Microwave Studio® commercial software packages. The computer-based modeling was verified by physical experiment. The analysis showed that it is possible to control the delay time characteristic using different values of lumped inductive elements without the need to change the overall size of the hybrid meander structure. The delay time varied by 1.2 ns in the range of 1.3 ns to 2.5 ns when the inductivity changed from 1 nH to 10 nH in our investigation. On the other hand, the passband decreased from 2.384 GHz to 0.508 GHz. The additional shields and their grounding positions allowed for increasing the passband by up to 1.6%.

“…Наибольший интерес представляют широкополосные усилители типа лампы бегущей волны (ЛБВ) с выходной мощностью порядка десятков W. С целью повышения мощности и КПД таких устройств целесообразно использование пространственно-развитых замедляющих систем (ЗС) и электронных пучков (ЭП) с большим поперечным сечением, в частности, ленточных. В частности, перспективными представляются планарные ЗС на диэлектрических подложках [3][4][5][6][7][8][9]. Они обладают большим замедлением, что позволяет снизить рабочие напряжения, сократить продольные размеры и массу прибора.…”
