Abstract:
Both in space-borne and ground instruments for cosmic microwave background (CMB) astrophysics, there is a need for large arrays of bolometers with some spectral resolution capabilities. We propose a design for a pixel composed of a planar antenna and a stripline diplexer optimized for two photometrics bands centered on 150 GHz and 220 GHz. The microwave circuit is suitable for an integration in a current antenna-coupled bolometer array. The complexity of the circuit depends on the requested bandwidth and frequency rejection. The proposed design is based on a stripline coupler with a stub circuit to achieve the correct impedance matching between the antenna and the bolometer in the desired waveband. The analysis of the antenna impedance and the radiation diagram is based on the HFSSTM software. The microwave circuit is then optimized by simulation with the Advanced Design System (ADSTM) from Agilent.
