نویسندگان
چکیده
This paper proposes a single circular radiator with multi-port (SRMP) antenna that can estimate the direction-of-arrival (DoA) in azimuth and elevation directions. The proposed SRMP is designed to minimize size of ultra-wideband system by using only one patch radiator. To verify feasibility, fabricated, reflection coefficient boresight gain are measured (-13.3 dB 3.4 dBi at 8 GHz). Then, observe direction-finding performance, DoA estimation results Bartlett beamformer compared typical array. At all incident angles, root-mean-square error less than 1° observed when signal-to-noise ratio higher 6 dB.
