Embodiment 1

[0037] Such as Figure 1a and 1b shown.

[0038] A radiation antenna single-port electromagnetic wave network includes a transmission line 2 and an electromagnetic wave channel 3 connected to the transmission line 2 . The electromagnetic channel 3 communicates with the transmission line 2 through one end surface thereof. The electromagnetic wave channel 3 is composed of a branch. The branch is composed of five through holes 31 connected along the Y direction.

[0039] The transmission line is a rectangular waveguide.

[0040] Both ends of the electromagnetic wave channel 3 are part of a plane A and a plane B respectively; one end of the electromagnetic wave channel 3 communicates with the transmission line 2 through one end of the transmission line 2 . At this time, the electromagnetic wave channel 3 is arranged on the end surface of the transmission line 2 .

[0041] The single-port electromagnetic wave network is a matching load. The other end of the electromagnetic wav...

Embodiment 2

[0047] Such as Figure 2a and 2b shown.

[0048] Compared with Embodiment 1, the main difference is only that: the cavity 5 is an open structure, constituting a radiator. The radiator adopting the electromagnetic channel of the shape disclosed in the present invention can effectively widen the working bandwidth of the radiator on the basis of ordinary rectangular, circular or elliptical electromagnetic channels.

Embodiment 3

[0050] Such as Figure 3a and 3b shown.

[0051] Compared with Embodiment 2, the main difference is only that: there is no cavity 5, and the electromagnetic wave channel 3 constitutes a radiator. The electromagnetic wave channel 3 is arranged on the side of the rectangular waveguide transmission line 2 . This allows the radiator to be smaller in size and have a wider operating bandwidth.

Abstract

The invention discloses a radiating antenna single-port electromagnetic wave network. According to the single-port electromagnetic wave network, multiple rectangular through holes or through holes with other shapes are communicated with each other to form an electromagnetic wave channel and the electromagnetic wave channel is adopted to match with various kinds of single-port electromagnetic wavecircuits. The other end of the electromagnetic wave channel is communicated with outer free space; the single-port electromagnetic wave network is a radiating antenna. Compared with existing similar schemes, the modeling optimization computing efficiency of the single-port electromagnetic wave network can be significantly improved, the size of the single-port electromagnetic wave network is smaller and the working bandwidth is broader. The single-port electromagnetic wave network is mainly applied to communication and radar systems of electromagnetic wave band, millimeter wave band and terahertz wave band.

Description

technical field [0001] The invention relates to an electromagnetic wave element, in particular to a single-port matching load, mismatcher or radiation antenna unit. Background technique [0002] In various electromagnetic wave systems, single-port networks are ubiquitous. According to needs, the input end of the single-port network is generally a matching end, and all electromagnetic waves entering the input end are absorbed or radiated into free space. For example, in a matched load, we want all electromagnetic waves entering the input to be absorbed. In a radiating antenna, we want all signals entering the input to radiate into free space. In some cases, such as in a mismatcher, we want the signal entering the input to be partially reflected and partially absorbed. At this time, we generally hope that the reflection coefficient or standing wave ratio at the input end meets certain requirements. Sometimes, we also want the phase of the reflection coefficient to meet cer...
