Özet

© 2021 IEEE.In this paper, we show and compare the results in radar cross-section (RCS) between metamaterial-based _textlow/40 low profile tactical UHF SATCOM antenna, operates in the band of 245 MHz - 310 MHz, and conventionally /4 sized aperture. The monostatic RCS results of both differently sized apertures have been examined in the frequency range of the S-band, under both theta and varphi-polarized plane wave incidence angle up to 60°. A reduction of one-tenth in antenna profile yields a considerable decrease in RCS.
