High-Performance Ka-Band Microstrip Patch Antenna for Next-Generation Networks at 33 GHz

A proposed microstrip patch antenna, powered through microstrip feeding and tailored for Ka-band applications (30–40 GHz), signifies a notable advancement in antenna technology. This work is particularly pertinent to next-generation network applications, with a specific focus on the frequency of 33 GHz. The antenna is fabricated using the Rogers RT/Duroid 5880™ substrate, renowned for its distinct attributes. Notably, it boasts a remarkably low dielectric loss tangent of 0.0009, coupled with a relative permittivity of 2.2 and a thickness measuring 1mm. These characteristics render it well-suited for antennas necessitating minimal signal attenuation, effective concentration of electromagnetic waves, and meticulous dimensional management. Simulation and thorough analysis of the antenna's performance have been conducted using Ansoft HFSS. This comprehensive assessment of radiation performance parameters is crucial to ensure that the microstrip patch antenna functions effectively within the specified Ka band frequencies, thus aligning with the requirements of next-generation network applications.
