Abstract
This paper proposes a novel compact Circularly-polarized antenna with four sequentially rotated elements operating at 280/433 MHz. The radiation body of the antenna is formed by four sequentially rotating arranged mono-pole antenna elements with meander arms. Adopting this element structure can effectively reduce the size of the antenna. To feed the Circularly-polarized array antenna, a compact feeding network based on Wilkinson power divider is also proposed, achieving four-way power splitting and 90° phase shifting. By this way, a sequential rotation array antenna with compact size (0.21λ0× 0.21λ0 × 0.006λ0), ease of integration, low fabrication cost and good performance is realized.
