A low profile and compact (26×13×4 mm3) folded strip monopole antenna is proposed for multiband mobile phone applications. The antenna simply consists of a main strip (folded monopole) coupled with an inner split ring resonator. To offer both compactness and multiband, the inner rings are edge-coupled with the main strip. The design covers applications like GSM 850, PCS 1900, and LTE 2500. A prototype is fabricated and tested; the simulated results are found to be in good agreement with the collected and calculated measured ones. The results showed that the proposed antenna can be a good candidate for recent hand portable devices.
