Abstract
This research proposes a compact dual-band patch antenna for 5G mmWave wireless communication applications. The 5 × 4.8 × 0.508 mm3 sized antenna is made of Rogers RT/duroid 5880(tm) dielectric material and is fed via a 50-Ω microstrip feedline. A rectangular slot was used on the radiating patch to create resonance at the 30GHz band from 29.2GHz to 31GHz. Another slot was etched from the ground to obtain another resonance at 49GHz from 48GHz to 50.1GHz. The S11 of -10dB and VSWR of less than 2 indicates that the designed bands have strong impedance matching capabilities. Peak gain of 4.99 dBi at 30GHz and 7.39 dBi at 49GHz are attained, as well as maximum radiation efficiency of more than 90% and sustained omnidirectional radiation characteristics are achieved. The results demonstrate that the suggested antenna is appropriate for next-generation wireless applications.
