Abstract

The invention provides a VHF and UHF waveband antenna which comprises a top loading plate, a conductive floor and a radiator, and the radiator is arranged between the top loading plate and the conductive floor. The radiator comprises at least one connecting part and at least one bending part, and the at least one connecting part is connected with the at least one bending part; the top end and the bottom end of the at least one bending part are respectively connected with the top loading plate and the conductive floor; and the two sides of the radiator are provided with at least two gaps. According to the VHF and UHF waveband antenna, miniaturization and broadband of the antenna are realized, and meanwhile, the antenna has relatively high gain and a good radiation pattern and can be used for an airborne VHF / UHF communication system.

Description

【Technical field】 [0001] The invention relates to the technical field of antennas, in particular to a VHF and UHF band antenna. 【Background technique】 [0002] As an omnidirectional antenna, the monopole antenna has excellent radiation performance and is widely used in many communication devices. Ground radio stations, vehicle radio stations, individual backpacks, ships, and aircraft are all equipped with various monopole antennas. In the VHF / UHF frequency band, the size of the omnidirectional monopole antenna is generally relatively large, which is not conducive to the concealment of the installation of the antenna. The airborne knife antenna is also subject to its aerodynamic shape, so it is necessary to miniaturize the broadband of the monopole antenna . It is difficult for existing monopole antennas to satisfy broadband, miniaturization and high gain simultaneously. 【Content of invention】 [0003] The technical problem to be solved by the present invention is to pro...
