Abstract: A storage station for unmanned vertical take-off and landing (VTOL) aircrafts includes a storage case (110) for accommodating an unmanned VTOL aircraft therein, a first coupling member (120) having one end pivotably coupled to an inner upper surface of the storage case and the other end protruding out of the storage case by a pivoting operation, and a second coupling member (130) provided at the other end of the first coupling member, in which one end of a main body of the unmanned VTOL aircraft is coupled to the second coupling member, and the second coupling member is rotatable about a rotation axis in a longitudinal direction of the first coupling member, whereby it is possible to provide an advantageous effect of simultaneously storing and charging multiple drones on sides, and it is particularly possible to provide an advantageous effect of charging and storing a large number of drones used in swarm flight technology, which has recently become increasingly useful.

Abstract: A filter manufacturing method and a filter manufactured by the filter manufacturing method are disclosed. The filter manufacturing method includes designating a use mode in a resonator to a first resonance mode, in response to designating to the first resonance mode, setting a band selected from a designated first frequency band to a passband in the resonator, switching the use mode in the resonator from the first resonance mode to a second resonator mode, in response to switching to the second resonance mode, setting a band selected from the first frequency band except for the passband to a stopband in the resonator, and manufacturing a primary filter including the resonator to which the passband and the stopband are set.
