PROJECT TITLE :

A Novel to Mode Converter Designed With Radially Loaded Dielectric Slabs

ABSTRACT:

A unique linear formed TM01 to TE1one mode converter having high efficiency and wide bandwidth is proposed. The design consists of a circular waveguide sectored by a horizontal metallic plate partition, and dielectric slabs radially hooked up in the lower semicircular waveguide. The mode converter is intended and simulated at an operating frequency of three GHz. A maximum bandwidth of 504 MHz (two.81-three.thirty five GHz) with conversion efficiency bigger than ninetyp.c is achieved when three Polytetrafluoroethylene (PTFE/Teflon) slabs are placed radially within the mode converter. The mode convertor was fabricated and experiments were performed with PTFE because the dielectric slab material. The mode conversion was verified by measuring the so much-field radiation pattern. The proposed mode converter is symmetric, compact, linear, and easy to fabricate. It will be used for S-band high-power microwave applications where wide bandwidth of mode conversion is required.
