Description

Technical Field

[0001] This utility model relates to the field of antenna technology, and in particular to a log-periodic antenna with a support structure. Background Technology

[0002] In existing log-periodic antennas, to ensure the strength of the support for the radiator, a non-metallic spacer is placed in the middle of the dipole arm and then secured with cable ties. Therefore, during operation, varying tension can lead to risks such as slippage of the non-metallic spacer and instability in intermodulation performance.

[0003] In existing log-periodic antennas, to enhance the support strength of the radiator and ensure the stability of the dipole arm spacing, non-metallic spacers, such as those made of nylon or PTFE, are typically placed in the middle of the radiator dipole arms on both sides of a metal base plate. Then, cable ties are used to quickly install and secure the spacers to the dipole arms. However, the effectiveness of the cable ties depends on the tension applied manually. If the operator does not apply force evenly or the cable ties become loose due to aging, the non-metallic spacers are prone to axial slippage or circumferential displacement. The loosening of the cable ties further exacerbates the slippage problem, causing damage to the antenna structure. Utility Model Content

[0028] An embodiment of this utility model provides a log-periodic antenna with a support structure 200, including a metal base 400, an antenna assembly, and a support structure 200. The antenna assembly is provided with a radiator 100 and a coaxial cable 300. One end of the coaxial cable 300 has a connector 500. The metal base 400 is provided with a metal base plate 150. One end of the radiator 100 is disposed on both sides of the metal base plate 150 and fixedly connected to the metal base plate 150. The coaxial cable 300 passes through the metal base 400 and is connected to the other end of the radiator 100. The support structure 200 is disposed in the middle of the radiator 100 and is connected to the radiator 100 by a snap-fit ​​engagement. The outer side of the support structure 200 is also snap-fitted to the coaxial cable 300. The support structure 200 is made of non-metallic material.

[0029] This invention employs a snap-fit ​​support structure 200 within the radiator 100. By replacing the traditional cable tie with a snap-fit ​​design of the support structure 200, the traditional cable tie is eliminated, thus removing the need for manual tightening and mitigating the impact of human error on the fastening effect. This log-periodic antenna with a support structure 200 avoids the risk of slippage of the spacer block 230 due to vibration, temperature changes, or long-term use, thereby solving the problems mentioned in the background art.

[0030] In one embodiment of this utility model, the radiator 100 includes an upper radiator 160 and a lower radiator 170. One end of the upper radiator 160 and the lower radiator 170 are fixedly mounted on both sides of a metal base plate 150, and the other ends of the upper radiator 160 and the lower radiator 170 are connected and fixed. The support structure 200 is disposed between the upper radiator 160 and the lower radiator 170 and is respectively snapped into the upper radiator 160 and the lower radiator 170. In this embodiment, the upper radiator 160 and the lower radiator 170 are distributed on both sides of the metal base plate 150 to ensure a uniform radiation field distribution. The support structure 200 is connected to the radiator 100 through a non-metallic snap-fit ​​component to avoid parasitic capacitance or inductance introduced by metal contact.

[0031] In one embodiment of this utility model, the lower radiator 170 is provided with an abutment plate 110 at its tail end, and the other end of the lower radiator 170 is connected to the upper radiator 160 through the abutment plate 110. Further, the coaxial cable 300 passes through the metal base 400 and connects to the abutment plate 110 of the lower radiator 170. In this embodiment, the abutment plate 110 serves as an extension structure of the tail end of the lower radiator 170, forming a rigid connection with the upper radiator 160, thus enabling the upper radiator 160 and the lower radiator 170 to form a closed force-bearing frame.

[0032] In one embodiment of this utility model, the upper radiator 160 and the lower radiator 170 are further provided with through holes, and the upper radiator 160 is fixedly connected to the lower radiator 170 by a pin passing through the through hole. In this embodiment, the upper radiator 160 and the lower radiator 170 are fixedly connected by an abutment plate 110 and a pin, forming a closed rigid frame, which can avoid the deformation caused by uneven force on the traditional single-layer radiator 100.

[0033] In one embodiment of this utility model, both the upper radiator 160 and the lower radiator 170 are provided with a central support arm 120 and a vibrator arm 130. The central support arm 120 and the vibrator arm 130 are integrally fixedly connected. The central support arm 120 is provided with multiple slots 140, and the support structure 200 is engaged with the slots 140 of the upper radiator 160 and the lower radiator 170. In this embodiment, the central support arm 120 and the vibrator arm 130 are integrally fixedly connected, eliminating the splicing gap of the traditional split structure and forming an integral load-bearing frame. The multiple slots 140 on the central support arm 120 are engaged with the support structure 200, avoiding the spacing deviation of the vibrator arm 130 caused by traditional cable ties or screw fixation. The clamping design of the support structure 200 replaces the traditional cable ties, eliminating the need for manual tightening of the cable ties and eliminating the influence of manual operation error on the fastening effect.

[0034] In one embodiment of this utility model, the support structure 200 is provided with a fixed side body, a fixed plate, and a spacer block 230. The fixed plates are respectively laterally fixed at both ends of the fixed side body, and the spacer block 230 is disposed between the two fixed plates and fixed to the fixed side body. The fixed side body and the fixed plates form a structure with an opening on one side. Further, a barb 220 is provided on the side of the fixed plate near the fixed side body, and the upper radiator 160 and the lower radiator 170 are respectively loaded into the gap between the fixed plate and the spacer block 230. In this embodiment, the support structure 200 forms a U-shaped open rigid frame structure through the combination of the fixed side body, the fixed plate, and the spacer block 230, replacing the traditional screw or glue fixing method. The open structure of the support structure 200 cooperates with the barb 220 of the fixed plate, so that the radiator 100 is pushed in for installation.

[0035] In one embodiment of this utility model, a snap fastener 210 is provided on the outer side of any one of the fixing plates, and the snap fastener 210 is engaged with the coaxial cable 300. In this embodiment, the snap fastener 210 on the outer side of the fixing plate is designed to allow the coaxial cable 300 to be directly pushed in and engaged without additional tools or fasteners.
