Abstract

This paper designs a miniaturized and ultrathin absorptive/transmissive radome based on interdigital square loops. The thickness of designed radome is only 4.5 mm. The period of the radome is 10 mm, which is λ/17.5 (λ corresponding to the wavelength of center frequency of passband). In order to verify the transmission and reflection properties, a prototype is fabricated. Its effectiveness is verified by both synthetic experiments and measurements in the anechoic chamber. Furthermore, the oblique incidents are also evaluated for both the transmission coefficients and reflection coefficients.
