Abstract :
This paper presents a novel design of waveguide-to-microstrip antipodal finline transition, which provides a broadband and low insertion loss performance. Meanwhile several factors affecting transition performance are taken into account. The design was verified experimental results at W-band, which has a coincidence with the results of simulation. Test results show that insertion loss fluctuates between 1.6 dB and 2.1 dB covering 75 GHz - 98 GHz. The insertion loss fluctuates between 2.4 dB and 3 dB in the frequency that ranges from 99 GHz - 110 GHz. The return loss fluctuates between 16 dB and 30 dB covering 75 GHz - 110 GHz. The compact transition design could decrease the effect of manufacture error.
