Resumen
Traveling wave tubes (TWTs) are linear beam-based microwave vacuumtubes usedfo ramplifyingpower. The high-power, high efficiency vacuum electronicamplifiersthat are used predominantly in space to ground satellite communication. High bandwidth,High power efficiency and light weight ofTWT makes it as a right choice forspace applications. Analysis of Ku-band folded waveguide TWT can be performedusing CST studio software for improving it’scharacteristics like gain, efficiency andbandwidth. Folded waveguide is used in TWT, as slow wave structure for increasingthe interaction between weak RF signal and electron beam. Characteristicsof slowwave structure includes materials for helical structure, axial length, pitch angle, circumferenceand operating frequency. The above parameters are varied and analysedfor the efficient TWT using the microwave CST studio software. With the above simulationthe power efficiency, returnloss and antenna gain of TWT are analysed forKu-band microwave frequency applications.
