Overview

Experimental study demonstrates dual-band resonance and high gain using parasitic patch loading, suggesting viable single-antenna integration for sub-6 GHz and millimeter-wave 5G systems.

Key Points

Design and validate a compact dual-band microstrip patch antenna using parasitic loading to support both sub-6 GHz and millimeter-wave frequencies for 5G applications.
Fabricated a 50 × 50 × 1.6 mm³ square microstrip patch antenna on a Rogers RT Duroid 5800B substrate (relative permittivity 2.2, loss tangent 0.0009).
Integrated strategically positioned parasitic patches and a half-ground plane to induce resonances in the 5G N79 (4.4–5.0 GHz) and N258 (24.25–27.5 GHz) bands.
Evaluated performance through simulation and physical measurements, assessing reflection coefficient, VSWR, gain, and radiation patterns.
Achieved dual-band resonance at 4.7 GHz and 26 GHz with reflection coefficients of –32.7 dB and –43.1 dB, respectively.
Maintained voltage standing wave ratio (VSWR) values below 2 across both target frequency bands.
Demonstrated peak gains of 5.29 dB at 4.7 GHz and 7.17 dB at 26 GHz, confirming strong agreement between simulated and measured radiation performance.
