Meander Conductor Shape Influence on the Electrodynamic Parameters of the Meander Structures

Abstract

Abstract – Meander structures allows reducing the size of the microwave devices while keeping the same operational characteristics. The shape of meander makes a big impact to the operation of microwave devices. Therefore, the structure of meander is widely investigated in nowadays. The review of different shapes of meander electrode is presented in this article. Two models with different shape of peripheral part of meander electrode are designed and discussed in details. The influence of variation of the length and width of peripheral part of meander electrode to 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 meander electrode is presented. The increase of the width of peripheral part of meander electrode from 0.2 mm until 1 mm has narrowed the bandwidth by 346 MHz until 2.388 GHz. The increase of the length of the peripheral part of meander electrode till 2.3 mm has allowed to move the stop-band to the higher frequencies. The usage of the rectangle-shape peripheral part of mender electrode slightly reduces the pass-band but allows to have a more stable input impedance.
