Embodiment Construction

[0023] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:

[0024] This power divider utilizes the principle of loop antenna, firstly designs a magnetically coupled waveguide microstrip probe in the form of a semi-circular ring; then realizes the magnetic coupling sharing of the two circular rings through symmetrical distribution, and jointly completes the transition from the microstrip TEM mode to the rectangular waveguide TE10 mode. conversion, and finally realize the function of power distribution and synthesis. When the two semi-circular probes are mirror-symmetrically arranged, the phases of the two microstrip ports are distributed in the same phase; when the two semi-circular probes are arranged symmetrically in 180° rotation, the phases of the two microstrip ports are distributed in anti-phase. More circuit design requirements can be adapted by adjusting the probe arrangement.

Abstract

A Ka-band double semicircular magnetic coupling power splitter. Based on the characteristics of the Ka-band circuit, the present invention designs a double-half-ring magnetic coupling power divider with a symmetrical structure according to the waveguide electromagnetic wave principle and the loop antenna theory. The common port of this power divider is BJ320 waveguide structure, and the distribution port is in the form of microstrip. The outlet positions of other usual E-plane microstrip probe distributors are different. It has a compact structure, small size and good performance, providing RF engineers with The new design method solves the problem of limited structure in the prior art.

Description

technical field [0001] The invention belongs to the field of circuit technology. Based on the characteristics of Ka-band circuits, according to the principle of waveguide electromagnetic waves, and in combination with the theory of loop antennas, a double semi-circular magnetic coupling power divider with a symmetrical structure is designed. In this power splitter, the common port is a BJ320 waveguide structure, the distribution port is in the form of a microstrip, and the phase of the port can be in phase or in reverse. Background technique [0002] With the rapid development of MMCI technology, more and more Ka-band millimeter wave circuits use planar MMIC chips to realize various functional radio frequency systems. Microstrip circuit has become the mainstream choice for Ka-band millimeter-wave circuit design due to its various circuit forms, flexible use, and convenient debugging. The waveguide circuit has become the main choice for power synthesis and signal transmissio...
