A High-Efficiency Dual-Band Inset-Fed Rectangular Patch Antenna featuring Precision Slot Configurations for Enhanced V-Band Millimeter-Wave 5G Applications

This research article comprehensively analyzes a high-efficiency, dual-band microstrip-modified rectangular patch antenna incorporating various slot configurations. The inset-fed antenna uses a Rogers RT/Duroid 5880 substrate, which measures 0.254mm in thickness. The proposed antenna exhibits dual-band resonance at the frequencies of 47.00GHz and 59.75GHz (V-Band) with return losses of -32.14dB and -19.69dB respectively. This antenna is meticulously designed and analyzed using HFSS. The sophisticated design process ensures optimal performance in advanced 5G wireless communication technology. The compact design dimensions of 6 × 7 × 0.254 make it ideal for space-efficient 5G systems. It shows a favorable real impedance of 49.3604 ohms and an imaginary impedance of -2.3708 ohms at 47 GHz. It achieves high efficiencies of 0.98 and 0.99 at 47GHz and 59.75GHz respectively. Thus, this antenna is versatile, operating effectively at 60 GHz. It offers a favorable gain of 5.29 dB and 2.36dB at 47GHz and 59.75 GHz respectively.
