Design and Parametric Analysis of 26 GHz Patch Antenna for mm-Wave Application

This research presents the design and analysis of a slotted microstrip patch antenna resonating at 26.08 GHz for millimeter wave (mm-Wave) communication applications. The study aimed to optimize critical antenna parameters, including gain, return loss, bandwidth, voltage standing wave ratio (VSWR), and radiation pattern characteristics. Various slot geometries and configurations were investigated on a rectangular patch surrounded by ring, with a co-axial feedline. The dimensional parameters of the slots were simulated and optimized using Ansys HFSS electromagnetic simulation software. The simulation results yielded dual resonating frequency at 26 GHz and 30 GHz, with a reflection coefficient of -25.87 dB- 3 3. 5 3 dB and VSWR of 0.88 dB, 0.36 dB respectively, indicating excellent impedance matching. The antenna demonstrated a gain of 9.26 dB(11.4 dBi) and an operational bandwidth of 1.169 GHz at the 26.08 GHz resonance frequency. These performance metrics were achieved through the strategic incorporation of symmetrically arranged slots on the patch surface. The proposed slotted microstrip patch antenna design exhibits promising characteristics for deployment in next-generation radio communication systems operating in the mmWave frequency band, addressing the growing demand for high-performance antennas in this spectrum.
