Abstract:
A single-feed miniaturized wideband circularly polarized (CP) antenna with metasurface is planned for L-band applications. The projected multilayered antenna comprises of a patch radiator with embedded ring-shaped slot and grounded-via, a stacked slit-slotted-circular patch, a metasurface with 5x5-unit cells, and a coaxial feeding probe. An antenna prototype at L-band exhibits -10-dB reflection coefficient(|S11|) bandwidth of 15.7% (1.488 GHz ̶ 1.742 GHz), 3-dB axial ratio (AR) bandwidth of 11.0% (1.50 GHz ̶ 1.675 GHz), and gain of 5.0dBic within the 3-dB AR-bandwidth with an overall size of 0.375λ0x0.375λ0x0.065λ0 at 1.5 GHz
