摘要: A simple microstrip antenna array which performs beam scanning without the use of electronic phase-shifters or delay lines is described. The incorporates mechanically rotatable patch antennas are designed for circularly polarised (CP) operation. Experimental results obtained from preliminary implementations provided and discussed.
