MICROSTRIP SWITCH Russian patent published in 1997 - IPC

FIELD: microwave devices. SUBSTANCE: device has dielectric substrate which one side carries grounding base and another side carries strip conductor to which sector loops are connected. Loops have different resonant frequencies. Strip conductor has slot in pieces in which loops are connected. Slot length is greater than length of piece in which loops are connected to conductor. Slot shape may be bent or narrowing to ends. Device may be used in design of radars, radio communication, satellite TV systems as switch for loads, elements of microwave filters and attenuators. EFFECT: increased quality of microwave switching in middle of bandwidth due to elimination of parasitic half-wave resonance; increased relative bandwidth, simplified manufacturing. 2 cl, 5 dwg
