A Meander Line Integrated Rectangular Tri-Band Antenna for 5G Sub-6GHz Applications

A meander line integrated rectangular tri-band microstrip antenna is proposed for 5G communication applications. The antenna is made of FR-4 material as the dielectric medium, and the optimized antenna dimensions are 0.22λ_L × 0.29λ_L × 0.012λ_L. The antenna operates at cental frequencies of 2.31, 3.75, and 5.52 GHz, with peak gains of 3.17, 2.22, and 2.69dBi, respectively. The −10 dB bandwidths are of 80 MHz (2.27–2.35 GHz), 810 MHz (3.39–4.20 GHz), and 580 Hz (5.17–5.75 GHz), with relative bandwidths of 3.5%, 21.3%, and 10.6%, respectively. The measured results are in good agreement with the simulated ones, which verifies the effectiveness of the antenna design. The far-field radiation are stable, guaranteeing good performance in the tri-band range.
