[0003] However, the above method of using a throttle or increasing the spacing between the radiation elements in the broadband omnidirectional collinear array antenna will increase the length of the broadband omnidirectional collinear array antenna, and the use of a throttle or increasing the width of the broadband omnidirectional The spacing between the radiating elements in the collinear array antenna cannot reduce the impact of the metal support in the broadband omnidirectional collinear array antenna on the broadband omnidirectional collinear array antenna. In addition, how to obtain a wider Working bandwidth is also one of the difficulties in the design of broadband omnidirectional collinear array antennas

The invention provides a balanced dipole unit and a broadband omnidirectional collinear array antenna composed of it. The balanced dipole unit circuits in the balanced dipole unit are symmetrically distributed on both sides of the circuit carrier, and the feeder The wires and ground wires are also symmetrically distributed, so that the balanced dipole unit has a completely symmetrical structure. The principle of this symmetrical structure is the same as the differential design principle and self-balancing principle in circuit design, so as to reduce the balance between the balanced dipole units. Current coupling, when the broadband omnidirectional collinear array antenna is composed of it, no additional choke circuit is needed, thereby reducing the length of the broadband omnidirectional collinear array antenna, and this symmetrical structure design can reduce the impact of the metal support on the broadband Radiation effects of an omnidirectional collinear array antenna. In addition, by introducing an open slot into the balanced dipole unit circuit, the current distribution of the circuit can be changed to generate multiple resonance frequency points, and the working bandwidth of the broadband omnidirectional collinear array antenna composed of it can be improved.
Description
technical field [0001] The invention belongs to the technical field of antennas, and more specifically relates to a balanced dipole unit and a broadband omnidirectional collinear array antenna. Background technique [0002] With the development of mobile communication technology, broadband omnidirectional collinear array antennas with omnidirectional radiation function have been widely used, such as applying broadband omnidirectional collinear array antennas to wireless communication systems, and in order to improve broadband omnidirectional collinear array The radiation gain and efficiency of the antenna require the use of additional choke circuits such as throttles in the broadband omnidirectional collinear array antenna or increase the spacing between the various radiation elements in the broadband omnidirectional collinear array antenna to reduce the radiation The current coupling between elements is used to improve the radiation gain and efficiency of the broadband omni...
