A new type of planar waveguide magic t

Abstract

The invention discloses a new type of planar waveguide magic T, including E-plane waveguide common port, H-plane waveguide common port and two branched waveguide ports, E-plane waveguide common port, H-plane waveguide common port and two branched waveguide ports. The center of the waveguide port is on the same plane. There is a protrusion at the connection between the H-plane waveguide and the E-plane waveguide and the cavity of the two branched waveguides. The width of the protrusion is consistent with the width of the H-plane waveguide. The connection between the protrusion and the E-plane waveguide There is a step, the connection between the protrusion and the H-plane waveguide has a step, and the position opposite to the protrusion has a step at the connection between the H-plane waveguide and the E-plane waveguide. The present invention reduces the height of the magic T of the waveguide. It has the advantages of large working bandwidth, superior performance, and good amplitude and phase consistency. And the structure is simple, the whole product is assembled with only two parts completely machined, no need to install other parts, the tolerance is easy to guarantee, and it has the characteristics of high production efficiency and low production cost.

Description

technical field [0001] The invention belongs to the technical field of electronic communication, and in particular relates to a novel planar waveguide magic T used in systems such as wireless communication, radar electronic warfare equipment and weapon guidance equipment. Background technique [0002] The waveguide magic T is a power distribution passive device, because of its large power capacity, and simple structure, it is easy to manufacture. It is widely used in radar system equipment, guidance system equipment, microwave communication equipment and microwave test system. It is often used as components such as power distribution, power synthesis, power deployment, and differential network. [0003] Ordinary waveguide magic T has two disadvantages: 1. The height direction is relatively high, which will make the volume and weight of the whole system relatively large; 2. The two common waveguide ports are perpendicular to each other and are not on the same plane, which is...
