Problems solved by technology

However, since the TE01 mode of the circular waveguide is the fifth higher-order mode in the circular waveguide, in the traditional petal-type mode converter, the suppression of the low-order modes in the circular waveguide is not enough, and the excited TE01 mode in the circular waveguide is impure, resulting in The system is unstable

Embodiment Construction

[0019] The following describes the embodiments of the present invention in detail with reference to the accompanying drawings: this embodiment is implemented under the premise of the technical solution of the present invention, and provides detailed implementation and specific operation procedures, but the scope of protection of the present invention is not limited to the following 的实施例。 Example.

[0020] Such as figure 1 , 2 As shown, this specific embodiment is a new type of rectangular waveguide TE10-circular waveguide TE01 mode converter in the 8 millimeter wave band. In the embodiment, the radius of the output circular waveguide with one end short-circuited is very important. In this embodiment, the radius selection rule is: to meet the transmission of the required working mode TE01, while suppressing the transmission of the lower higher order modes, the radius of the circular waveguide is selected as r=6.4mm, which is recorded as port 1. The four input rectangular waveguide...

Abstract

The invention discloses a novel rectangular waveguide TE10-circular waveguide TE01 mode converter; the mode converter can convert the rectangular waveguide TE10 mode into the circular waveguide TE01 mode, and can well prevent transmission of a plurality of low order modes, so the obtained circular waveguide TE01 mode is high in purity. The novel rectangular waveguide TE10-circular waveguide TE01 mode converter is small in insert loss, concise in circuit framework, can be realized by existing process and technical conditions, and has very well application prospect.

Description

Technical field [0001] The present invention relates to the field of microwave and millimeter wave technology, in particular to the field of millimeter wave solid-state power synthesis technology and high-power transmission. Background technique [0002] There are many transmission modes in circular waveguides, among which TE11 mode, TE01 mode and TM01 mode are the three most commonly used modes. Among them, the TE11 mode is the lowest mode of a circular waveguide. Since polarization degeneration is prone to occur, it is generally not used as a transmission mode. However, it can be used to make microwave devices such as polarization attenuators and poles. The characteristics of the TM01 wave are that the electric field is radially axisymmetrical, and the wall current has only longitudinal components, which can be used as the rotary joint in the antenna feed system or the resonant cavity in the linear electron accelerator; the field distribution of the TE01 wave has an axis Symme...
