Dual-band CPW-fed slot antenna for LTE and WiBro applications

摘要: In this article, we present a dual-band coplanar waveguide-fed slot antenna for 1.7/2.3 GHz long term evolution and wireless broadband frequencies. The proposed is fabricated on an FR4 substrate with dielectric constant of 4.4. By cutting pair rotated T-shaped slits in the circular radiating stub, new resonance at lower frequencies generated, also by embedding meander-line slit ground plane good operation can be achieved. measured impedance bandwidth 10 dB return loss from 1.57 to 1.73 (13%) 2.21 2.38 (10.0%), covering operations. Simulated experimental results obtained show that has gain radiation behavior. © 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:1013–1015,
