Abstract

The invention discloses an antenna array element and an ultra wide band tight coupling antenna array. The antenna array element comprises a radiation unit, a feed unit and a reflection floor, and further comprises an inductive loading structure, the inductive loading structure is arranged between the radiation unit and the reflection floor, and an equivalent inductance is used for counteracting a short-circuit effect generated by the reflection floor. According to the tight coupling antenna designed by the invention, an impedance bandwidth is doubled through the inductive loading structure on the basis of not introducing loss, the antenna has relatively high radiation efficiency, the impedance bandwidth exceeds 10 octaves, the radiation efficiency is greater than 90%, and the relative bandwidth exceeds the relative bandwidth of most antenna arrays at the present stage while s relatively high radiation frequency is ensured.

Description

technical field [0001] The invention relates to the technical field of ultra-wideband phased array antennas, in particular to a tightly coupled antenna array loaded with an inductive structure. Background technique [0002] With the development of the Internet of Things and communication technology, ultra-wideband phased array antennas have received widespread attention in the field of commercial communication and detection. In the future, electronic devices not only need to perceive the surrounding environment information, but also need to adapt to changes in the surrounding environment and communicate the external environment to different terminals. This requires that the antennas of electronic devices need to work in different frequency bands to meet different functional requirements, and It has higher radiation efficiency to perceive more complete surrounding information and longer communication distance. If antennas with different operating frequencies are integrated o...
