The Front-End Design of a Hydrogen Spectral Line Receiver for Micro Satellite Navigation
Regarded as a promising source for future spacecraft navigation, the change in the energy state of neutral hydrogen atoms can provide a super stable electromagnetic radiation in the microwave region. Inspired by this concept, this paper specified the instrumental development of designing the front-end of a Hydrogen Spectral Line(HSL) Receiver receiver to support the micro-satellite navigation in space. The design included a array of 37 copper patches aligned in hexagon. Each patch was fed by microstrip lines to connect a 2-stage low noise amplifier. The a digital phase shifter was yielded to implement the phase control and electrically beam forming. The numerical simulation result showed that this front-end would provide a total 31.7dB gain and beam scanning angle between ±40 degree.
