Abstract

A multiband planar antenna fed by an asymmetric coplanar waveguide (ACPW) is proposed and fabricated. The design incorporates branched stubs within the split-ring resonator (SRR) and integrates this modified SRR with the ACPW structure, thereby expanding the antenna's operational bandwidth and improving gain performance. The antenna has dimensions of 60 mm × 58 mm × 0.813 mm, which are equivalent to 0.48λ₀ × 0.46λ₀ × 0.0065λ₀ at 2.4 GHz. Simulation and measurement results demonstrate close agreement. The antenna exhibits |S₁₁| < -10 dB in the frequency bands of 2.23-2.51 GHz, 3.54-4.47 GHz, and 5.01-6.29 GHz, with a maximum gain of 7.07 dBi at 5.1 GHz and over 2.5 dBi gain across all bands. This antenna meets the requirements for WLAN, UAV communications, and 5G applications.
