Microwave Power Limiter Having H-Shaped Slot Structure With Enhanced Plasma Discharge by Electrostatic Potential

A microwave power limiter with an H-type slot structure is proposed as a waveguide structure that blocks high-power microwaves through plasma discharge.At an operating frequency of 5.75 GHz, the electric field is concentrated in the discharging electrode gap; when high power is applied, the plasma limiter discharges, and low power is transmitted.By
