In this article, a miniaturized, dual-polarized corner-fed microstrip antenna is designed and fabricated at 1.43 GHz for Low Earth Orbit (LEO) Satellite applications. The antenna adopts a Complementary Split-Ring Resonator (CSRR)-inspired structure and slotted patch to achieve miniaturization. This reduces the patch size by 39.4%. Meandered impedance-transforming lines are placed for impedance tuning, and its benefit is demonstrated by both simulated and measured S11 curves reaching lower than -20 dB. Feeding at corner increases its isolation to -25 dB over the whole bandwidth of 40 MHz and reaches lower than -33 dB at the resonant frequency. The antenna is fabricated and tested. Measured results are generally in good agreement with simulations.
