The invention discloses a band stop type frequency selection surface based on a low dielectric meta-material. The band stop type frequency selection surface comprises three layers of polymer medium substrates and air layers which are between two adjacent polymer medium substrate layers, the polymer medium substrates are etched into square aperture structures having different edges, the polymer medium substrates employ low dielectric low loss polymer medium substrates and are prepared to form a continuous period array, and FSS band stop characteristics can be developed and optimized through adjusting square unit structure edges. According to the band stop type frequency selection surface based on the low dielectric meta-material, the low dielectric polymer substrates are employed, any metal material is not contained, and advantages of low loss, high power capacity and low detectability are realized, moreover, band stop characteristics at a microwave band can be realized, simple design is realized, and strong adjustability is realized.
