Description

technical field [0001] The invention relates to the technical field of low-frequency communication, in particular to a method for evaluating the performance of a rotary electret mechanical antenna based on simulation modeling. Background technique [0002] In September 2017, DARPA (Defense Advanced Research Projects Agency) of the United States launched a 45-month "Mechanically Based Antenna" project (A MEchanically Based Antenna, No.: HR001117S0007) with a cost of 23 million US dollars. The radio frequency signal is generated by the body or permanent magnet material for propagation. This method can greatly reduce the volume and power consumption of the transmitting antenna of the low-frequency navigation communication system, and realize a major transformation and subversive innovation of the radio transmitting system. Seek to use the advantages of ultra-low frequency (ULF) and very low frequency (VLF) radio waves to achieve strategic ultra-long-range and penetrating commu...
