Description

Foldable rod-shaped antenna

Technical Field

The utility model relates to the technical field of antennas, concretely relates to collapsible rod antenna.

Background

The antenna is a converter which converts a guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium or vice versa, and is a component for transmitting or receiving electromagnetic waves in radio equipment, and engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasure, remote sensing, radio astronomy and the like, all of which transmit information by using electromagnetic waves rely on the antenna to operate. The external rod-shaped antenna belongs to the category of antennas, can be used for communication interaction equipment such as wifi and unmanned aerial vehicles, is low in anti-interference capacity, different in different regions, different in climatic conditions and magnetic field environments and different in receiving sensitivity, and cannot receive complete signals due to excessive signal attenuation during signal transmission by using a feeder line after the external rod-shaped antenna receives signals.

Disclosure of Invention

An object of the utility model is to provide a simple structure's collapsible rod antenna can receive signal steadily, reduces the signal attenuation coefficient of feeder, receives complete signal.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

Detailed Description

The technical solution in the embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in fig. 1 and 2, a foldable rod antenna comprises a body 1, a folding member 2 is arranged at the bottom of the body 1, a hinge shaft 3 for hinging the body 1 and the folding member 2 together is arranged between the body 1 and the folding member 2, a feeder 4 is arranged in the folding member 3, one end of the feeder 4 is connected to the body 1, and an IPEX connector 5 is arranged at the other end of the feeder 4.

Further, the size of the body 1 is Φ 13x155mm or Φ 13x195 mm.

Further, the feeder line 4 is an RG178 line, the length of an exposed line of the feeder line 4 is 250mm or 400mm, and the bending radius of the feeder line 4 is 10 mm.

Further, the operating frequency range of the feeder 4 is 100 to 3000 MHz.

Further, the signal attenuation coefficient of the feeder line 4 ranges from 0.453 dB/m to 2.572 dB/m.

In this embodiment, as can be seen from fig. 3, 4, 5 and 6, according to the requirement of the actual site, the direction in which the body 1 is aligned is adjusted by the folding member 2, and after the body 1 receives a signal, the standing wave ratio of the present invention is substantially greater than or equal to 1 and the return loss is low, the impedance of the body 1 is completely matched with the feeder 4, and the body 1 can stably receive a complete signal; after the utility model starts to work, the working efficiency and the gain coefficient both gradually rise and then tend to be stable, the higher signal receiving sensitivity and the higher signal transmission efficiency are kept, and complete antenna signals are received; the utility model discloses holistic simple structure is applicable to large-scale production and uses.
