Exploring Innovative 3D Printed Umbrella-Shaped Antenna at 28 GHz for Next-Gen 5G Technology

This research project explores the potential of 3D printing technology for producing compact umbrella-shaped antennas for 5G applications at 28GHz. The use of 3D printing allows for a reduction in production costs while still meeting desired performance specifications. The proposed antenna design operates within a frequency range of 20GHz to 40GHz, making use of the umbrella shape, which is known for its advantageous properties in the LF and VLF bands, including short wavelength, low radiation resistance, and efficient radiation of power. To validate the design, simulation was performed using CST Studio Microwaves version 18 and the performance of the antenna was analyzed in terms of gain, return loss, voltage standing wave ratio (VSWR), and radiation pattern at 28GHz. This study contributes to the field by demonstrating the feasibility of 3D printed antennas for 5G applications and highlighting the benefits of the umbrella shape for this specific frequency range.
