CPW-Fed Dual-Band Bow-Tie Slot Antenna for WiFi and 5G Sub-6 GHz

A CPW-fed bow-tie antenna with integrated stubs is designed for dual-band operation, resonating at 2.5 GHz and 5.7 GHz, making it suitable for WiFi (2.4 GHz, 5 GHz) and 5G Sub-6 GHz (n77/n78) applications. The incorporation of stubs enhances impedance matching and introduces additional resonances, ensuring a return loss (S11) below −10 dB across both bands, with a peak resonance of −17.14 dB at 5.7 GHz. The antenna exhibits a compact form factor while maintaining wideband characteristics and stable radiation performance, making it a viable candidate for next-generation dual-band wireless communication systems.
