Abstract :
In this work, a novel antipodal linearly tapered slot antenna (ALTSA) using grounded coplanar waveguide (GCPW)-to-substrate integrated waveguide (SIW) transition is proposed and demonstrated. The antenna is well designed for using as the feed antenna in the focal plane array (FPA) imaging system. The S11 of the proposed antenna is below −13dB on Ka-band, meanwhile, the E-plane side lobe is almost 15dB down and 40dB down after reflecting by a parabolic antenna when placing along a line on its focal plane, which show us its high availability for passive millimeter-wave (PMMW) focal plane array imaging system.
