Description
Technical Field
The invention relates to a communication antenna, in particular to a low-impedance multi-source excited rectangular loading meander line antenna.
Background
Terahertz (THz) waves are electromagnetic waves of 0.1-10 THz, and THz communication has the advantages of large capacity, high transmission rate, high safety, strong directivity, good penetrability and the like due to the considerable absolute bandwidth. However, due to the severe atmospheric attenuation of the THz band, higher demands are placed on the emitters and detectors of the THz band. Efforts have been made to increase the power of the THz source and the sensitivity of the THz detector.
Superconducting devices are of great interest due to their low power consumption and low noise. However, superconducting josephson junction devices have a relatively low impedance, typically 0.1 to 40 Ω in normal state resistance, which is not the case with conventional receive antennas. The series configuration may increase the impedance of the devices to achieve impedance matching with the coupled antenna, but the impedance mismatch between the antenna and the respective low impedance devices in series still exists. The development of a novel THz antenna with low impedance multi-source excitation for low impedance devices in series is needed.
On the other hand, loading techniques are used to adjust the input impedance of the antenna. Currently, butterfly loading is applied to resonant THz antennas to achieve low impedance matching. However, the butterfly shape is oversized relative to the THz device, resulting in chip waste, and is suitable for the lack of compact THz antennas with low impedance serial devices.

Detailed Description

As shown in fig. 1, a rectangular loaded meander line antenna suitable for low impedance serial devices includes a plurality of low impedance devices 1, a meander line metal layer 2 sequentially connecting the plurality of low impedance devices 1, and a pair of rectangular metal layers 3 loaded at the head and tail of the meander line metal layer 2. The rectangular loaded meander line antenna is symmetrical about a center point and is disposed on a dielectric substrate.
The rectangular loaded meander line antenna works in a traveling wave mode, the impedance of the multi-source excitation is based on an actual low-impedance device, and the lengths and the widths of the meander lines connected with the low-impedance device can be unequal so as to adjust the magnitude of the active impedance. The total length of the meander line can be adjusted to place the desired number of low impedance devices.
In practical application, the number of the placed series low-impedance devices is determined by adjusting the length and the spacing of the meander lines, and the working frequency is determined by adding the length of the rectangular metal layer, wherein in the embodiment, 7 low-impedance devices are included and corresponding to 7 excitation sources. And a silicon hyper-hemispherical lens or an electromagnetic band gap structure is arranged on the back surface of the medium substrate and is used for eliminating the surface wave effect of the antenna structure.
As shown in the figure 2 of the drawings,in this embodiment, in the CST simulation software, the antenna material is set as an ideal conductor, and is placed on a magnesium oxide (with a relative dielectric constant of 9.6) substrate, and the low impedance device is represented by a 15 Ω discrete port, so as to perform multi-source excitation simulation, and the discrete port on the meander line can be increased or decreased according to practical applications. The antenna parameter l=46 μm, w=294 μm, t=3 μm, c=8 μm, g 1 ＝g 2 ＝4μm，g 3 ＝2μm，h 1 ＝h 2 ＝10μm，h 3 When=5 μm and h=17 μm, the active reflection coefficient under the excitation of 7 active ports and the 375GHz far-field radiation pattern are shown in fig. 3 and fig. 4, respectively, and the 375GHz directivity coefficient can reach 8.76dBi.
The foregoing is merely a preferred embodiment of the present invention and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present invention, which are intended to be comprehended within the scope of the present invention.
