S-band Wideband High-gain Circularly Polarized Antenna Array
This paper presents a $1 \times 3$ microstrip antenna array fed by a microstrip T-segment power splitter and a branch line coupler. The antenna array operates in the S-band from 2.14 GHz to 2.75 GHz and consists of a circular-polarized(CP) microstrip antenna unit, a probe, a branch line coupler and a T-segment power spliter. After the array, the relative bandwidth of the antenna array is 25.8%, the gain is greater than 10 dBic in $2.2 \mathrm{GHz} \sim 2.5 \mathrm{GHz}$, and the half-power beamwidth is greater than 24°.
