A Compact Receive Module in 3D Printed Vivaldi Antenna

Using a combination of 3-D printing and thin-film processes, a compact microwave front-end module is designed and fabricated. An ultrawideband Vivaldi antenna with a structurally embedded receive module is demonstrated. The receive module is placed in a packaging cavity that is formed in the unused region of the antenna structure. The measurements of this 3-D printed system are compared to a tradi...
