Meander structures allow reducing the size of the microwave devices while keeping the same operational characteristics. The shape of meander makes a considerable impact on the operation of microwave devices. Therefore, the structure of meander is widely investigated nowadays. The review of different shapes of a meander conductor is presented in this article. Two models with different shape of connecting conductors are designed and discussed in detail. The influence of variation of the length and width of connecting conductors on the electrical parameters of the meander is revealed using the traditional model of meander. Later, the comparison of the traditional model and the model with rectangle-shape peripheral parts of a meander conductor is presented. The increase in the width of connecting conductors from 0.2 mm to 1.0 mm has narrowed the bandwidth by 346 MHz until 2.388 GHz. The increase in the length of connecting conductors to 2.3 mm has allowed moving the stop-band to higher frequencies. The usage of the rectangle-shape connecting conductors slightly reduces the pass-band but allows achieving more stable input impedance.

“…At this time, there is an urgent demand for high-efficiency and high-power TWTs, and the planar TWT which is compatible with higher-precision microelectronics machine system (MEMS) technology has become a new research hotpot [3][4][5]. The planar TWT mainly refers to planar slow-wave structures (SWSs), including rectangular spiral SWSs [6][7][8][9], microstrip meander-line SWSs [10][11][12], staggered double-gate SWSs [13,14], and folded waveguide (FWG) SWSs [15]. Microstrip meander-line SWSs have been studied intensively for years, because of their advantages of easy integration, easy processing, and suitability for sheet-beam operation [16][17][18][19].…”

A multiple dielectric-supported ridge-loaded rhombus-shaped meander-line (MDSRL-RSML) slow-wave structure (SWS) is proposed for a V-band wideband traveling wave tube (TWT). The high-frequency and transmission characteristics of the SWS are investigated. The proposed structure can realize stable output via attenuator and special phase-velocity jumping. Particle-in-cell (PIC) results indicate that, for a 7 kV, 0.1 A sheet-beam, the average output power can reach 60 W at 60 GHz and a 3 dB bandwidth of 9 GHz, with the corresponding gain and electron efficiency of 30.8 dB and 17.2%, respectively. Compared with the dielectric-supported rhombus-shape meander-line (DS-RSML) SWS, the proposed structure has a wider bandwidth, higher gain, more stable structure, and better heat dissipation ability, which make it a good candidate source in millimeter-wave communications.
