The optimal annealing temperature was found to be 400°C, resulting in silver paste with resistivity of 6.72 × 10⁻5 Ω cm and surface roughness of 35.8 nm. The antenna showed return loss below − 10 dB, peak gain above 2.5 dB, and a 5B adhesion grade, demonstrating excellent performance and manufacturing potential.8enjournal article
