Horizontal polarization leaky cable for effectively restraining standing wave resonance peak value

Abstract

The invention discloses a horizontal polarization leaky cable for effectively restraining the standing wave resonance peak value. A leaky cable outer conductor groove hole is formed with a plurality of groups of horizontal polarization grooves according to a certain arraying and combining mode, the grooves can be the same or different in structure, and in order to avoid the interference problem caused by the increase of the number of grooves formed in a period, micro-interference standing wave compensation can be conducted on adjacent groove seams in each groove hole. According to the specificform, a series of periodic groove holes are formed in a stamping copper belt longitudinal wrap outer conductor, the groove holes are each of a linear horizontal polarization groove group structure, each linear groove group is composed of two or more lines of groove seams with the same width and chamfering size, the groove seam size in each groove group can be the same or different, and two or more linear groove groups are formed in each period. By changing the proportional size of groove seam bodies and the distance between the groove groups, and the effect of restraining the resonance peak value of the leaky coaxial cable under different use frequencies can be realized.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a horizontally polarized leaky cable that can effectively suppress the resonance peak of a standing wave. Background technique [0002] Broadbanding of leaky cables is the key point to be studied in the design of leaky cables. According to the common method of multimode suppression, slots can be regularly added on the surface of leaky cables to achieve the purpose of extending the frequency band. However, with the opening of each cycle As the number of slots increases, the mutual interference between the slots will become stronger and stronger, which will be reflected in the amplitude of the reflection coefficient, causing the leaky cable to have a standing wave resonance peak. The so-called standing wave resonance peak means that due to the slots on the surface of the outer conductor of the leaky cable, the reflection coefficients at each slot are different, and there is a ...

Problems solved by technology

[0003] According to the slot shape of the outer conductor of the leaky cable, two kinds of electromagnetic waves, horizontally polarized and vertically polarized, can be radiated respectively. Among them, the vertically polarized leaky cable can suppress the resonance peak of the standing wave by adjusting the angle and other dimensions of the slot hole in the period, while The structure of the horizontally polarized leaky cable is relatively simple, and the existing slot form cannot effectively suppress the standing wave resonance peak
