A 3-D Printed PCB Integrated TEM Horn Antenna

摘要

This paper presents a very broadband (5-40 GHz) novel three dimension (3-D) printed Transverse ElectroMagnetic (TEM) horn antenna. It is integrated with a planar Printed Circuit Board and radiates in a perpendicular direction of the Printed Circuit Board. The described antenna provides benefits in terms of cost and size for a two dimensional antenna array. Here the antenna and its corresponding transition to a regular 50 Omega microstrip line through Parallel Plate Waveguide and a 90 degrees bend are presented. Prototypes of back-to-back transitions and antenna are fabricated and measured. The antenna has a return loss below -10 dB and a gain of approximately 10 dBi over the targeted frequency range.
