AI Technical Summary
Existing frequency reconfigurable antennas, such as liquid crystal antennas, have long response times, making it difficult to meet the requirements for efficient frequency reconfiguration. This is especially true in 5G communication when receiving multi-band signals, where the increased number of antennas leads to electromagnetic interference and larger size.
By using microelectromechanical system (MEMS) switches with short response times as control devices, microstrip feed lines and antennas are spaced apart on the substrate. The antenna is controlled to conduct by controlling the switch, thereby achieving rapid frequency reconstruction and reducing response time.
It achieves rapid frequency reconstruction response, reduces electromagnetic interference, adapts to multi-band signal reception, and has a miniaturized antenna size, making it suitable for 5G communication equipment.
