Abstract

This paper presents a dual feed Circularly Polarized Compact Wideband Microstrip Patch Antenna for Launch Vehicle Telemetry Applications in S Band. The proposed dual polarized antenna employs a stripline quadrature hybrid coupler and has a 10dB impedance bandwidth of 930MHz (37%) from 2.08GHz to 3.00GHz while the 3dB axial Ratio bandwidth is 540MHz (22%) from 2.13GHz to 2.67GHz. The antenna has a maximum gain of 7.00dBi with 0.5dBi variation over the 3dB axial ratio bandwidth. The quadrature hybrid based design of the antenna using RT/Duroid 6002 substrate allows its use as either RHCP antenna or LHCP antenna.

S波段运载火箭遥测用圆极化紧凑型宽带微带贴片天线

本文提出了一种用于运载火箭S波段遥测的双馈圆极化紧凑型宽带微带贴片天线。该双极化天线采用带状线正交混合耦合器，在2.08GHz ~ 3.00GHz范围内10dB阻抗带宽为930MHz(37%)，在2.13GHz ~ 2.67GHz范围内3dB轴比带宽为540MHz(22%)。该天线的最大增益为7.00dBi，在3dB轴比带宽上有0.5dBi变化。采用RT/Duroid 6002基板的正交混合天线设计允许其作为RHCP天线或LHCP天线使用。
