PROJECT TITLE :

3-D Printed Microwave Patch Antenna via Fused Deposition Method and Ultrasonic Wire Mesh Embedding Technique

ABSTRACT:

In this work, the look, fabrication and characterization of a 3-d printed microwave patch antenna is presented. The antenna is fabricated by combining fused filament fabrication technique for the dielectric half and ultrasonic metal wire mesh embedding approach for the conductor part. Full wave finite-component simulations for various wire mesh structures and additionally the complete antenna are done to make positive the embedded wire mesh has sensible performance at microwave frequency. A microstrip patch antenna operating around 7.five GHz is printed and characterized to demonstrate the efficiency and accuracy of this method. The measured reflection coefficient shows a smart resonance peak at 7.5 GHz. The measured gain of this antenna is 5.5 dB at the resonance frequency. Good agreement between simulation and measurement is obtained in each reflection coefficient and radiation pattern.
