Description
NOVEL COMBINED UHF ANTENNA
Field of the Utility Model [0001] The utility model belongs to the technical field of wireless communications, and specifically relates to a novel combined UHF antenna.
Background of the Utility Model [0002] An UHF (Ultra High Frequency) antenna is composed of two portions: an antenna pedestal and an antenna body. Different antenna body lengths correspondingly allow achievement of different antenna gains. Existing antenna products usually have fixed antenna body length, leading to a need to provide antenna bodies different in length for satisfying multiple environmental gains. To this problem, there are following several improved schemes in the prior art:
[0003] 1) The antenna pedestal is provided with a plurality of antenna bodies different in length and capable of being assembled and connected therewith, and when in use, different antenna bodies are replaced on the antenna pedestal according to the requirements of the environmental gains. While this scheme can meet the requirements of multiple environmental gains, it requires provision of a certain number of antenna bodies, and the antenna body corresponding to the highest gain is quite long and thus not convenient for a user to store and carry.
[0004] 2) The antenna pedestal is provided with a plurality of segments of retractable or drawable antenna body, and the length of the antenna body is adjusted through a telescopic structure to meet the requirements of multiple environmental gains, wherein the segments of the antenna body match with each other through internal limiting structures and cannot be separated from the adjacent segments. Thus, even though some segments of the antenna body are damaged, the whole antenna must be replaced, resulting in cost waste.
Summary of the Utility Model
2019101306 29 Oct 2019 [0005] In view of the problems presented in the background part, the utility model provides a novel combined UHF antenna that meets the requirements of high and low gains in service environments and is also convenient for a user to carry, install and maintain. The utility model utilizes the following technical schemes.
[0006] A novel combined UHF antenna comprises an antenna pedestal, a rod-shaped main antenna body and a rod-shaped auxiliary antenna body. The main antenna body is disposed on the antenna pedestal and has a top end detachably connected to the auxiliary antenna body. A feeder passage allowing a feeder to pass therethrough is provided in the antenna pedestal such that the feeder is electrically connected to a feed point of the main antenna body through the feeder passage.
[0007] In the above scheme, the main antenna body serving as a base segment and the auxiliary antenna body serving as a connection segment are provided. The main antenna body may only be used in a place where antenna signals are powerful, whereas in a place where antenna signals are weak, the auxiliary antenna body may be directly connected to the main antenna body to achieve antenna gain enhancement.
[0008] In one or more embodiments of the present utility model, the main antenna body is in threaded connection with the auxiliary antenna body, and specifically, a first thread groove is formed in an end of the main antenna body or the auxiliary antenna body, while a threaded connection end joint matching with the first thread groove is formed on an end of the auxiliary antenna body or the main antenna body opposite to the first thread groove.
[0009] In one or more embodiments of the present utility model, a threaded through hole is formed in a sidewall of the first thread groove, and a bolt is screwed in the threaded through hole from outside with an end portion of the bolt against the threaded connection end joint screwed in the first thread groove. The bolt is used for strengthening and locking the auxiliary body to prevent loosing thereof in case of vibration of the antenna.
[0010] In one or more embodiments of the present utility model, the bottom end of the main antenna body is in detachable connection with the antenna pedestal, and the patterns of the
2019101306 29 Oct 2019 detachable connection include at least threaded connection, clamped connection, and embedded connection.
[0011] In the above scheme, the main and auxiliary antenna bodies can both be detached simply. In case of any segment having a problem, only this segment, rather than the whole antenna, needs to be detached for maintenance or replaced; thus, the maintenance cost of the antenna is reduced to the utmost extent.
[0012] In one or more embodiments of the present utility model, the antenna pedestal is connected with the main antenna body by means of a connecting piece having a longitudinal through inner cavity with threads formed on sidewalls of the inner cavity and thread parts provided for openings at both ends of the inner cavity, respectively; second thread grooves matching with the thread parts are formed in the antenna pedestal and the main antenna body, respectively.
[0013] In one or more embodiments of the present utility model, one end of each of the thread parts has a first diameter conforming to an inner diameter of each end of the inner cavity in the connecting piece, while the other end thereof has a second diameter conforming to an inner diameter of each of the second thread grooves.
[0014] In one or more embodiments of the present utility model, the feeder passage of the antenna pedestal communicates with the second thread grooves, and the feeder is electrically connected to the connecting piece screwed in the second thread grooves.
[0015] In one or more embodiments of the present utility model, the antenna pedestal comprises a base portion provided with a feeder joint, an antenna fixing portion, and a connecting portion for connecting the base portion with the antenna fixing portion.
[0016] In one or more embodiments of the present utility model, the connecting portion is a spring.
[0017] The present utility model has the following advantages:
2019101306 29 Oct 2019 [0018] 1) The main antenna body serving as the base segment and the auxiliary antenna body serving as the connection segment are provided. The main antenna body may only be used in a place where antenna signals are powerful, whereas in a place where antenna signals are weak, the auxiliary antenna body may be directly connected to the main antenna body to achieve antenna gain enhancement. Thus, the costs of the antenna bodies may be saved, and the maximum length of each antenna body is also reduced to the utmost extent to facilitate storage and carrying by a user.
[0019] 2) Threaded connection is employed between the base and the main antenna body and between the main antenna body and the auxiliary antenna body; thus, it is convenient for detachment and storage, and also conducive to fault detection, maintenance and replacement of the antenna.
[0020] 3) The main and auxiliary antenna bodies can both be detached simply. In case of any segment having a problem, only this segment, rather than the whole antenna, needs to be detached for maintenance or replaced; thus, the maintenance cost of the antenna is reduced to the utmost extent.
