Ultralight Wideband Open Boundary Quad-Ridged Antenna Manufactured Using 3D Printing Technology
Résumé
In this paper, authors propose to manufacture an ultra-wideband open boundary quad-ridged antenna using a 3D printing manufacturing method followed by a chemical metallization process. The lowest operating frequency has been decreased from 550 MHz to 300 MHz using dielectric slots. Furthermore, the structure of the antenna is optimized in term of weight and reached only 1100 g for an overall size of 442x442x442 mm3. Finally, measurements show good performances over the frequency band from 300 MHz to 6 GHz.
