Abstract

The design and measurement of low-profile folded patch antenna with a short-circuited element is presented. By introducing dual-resonance, a significantly improved bandwidth of almost 30% for S₁₁<-10dB, which ranges from 1.48 to 1.99GHz, is achieved, while the total profile of the proposed antenna is kept in a very low level of 0.046 λ₀ only. The impedance matching, radiation patterns, and gain curve are measured and illustrated. This antenna is easy to fabricate and its performance is less susceptible to the manufacturing errors. Due to its wideband and low-profile characteristics, it is highly suitable for applications in mobile communication systems, such as PCS, DECT and PHS.
