This paper presents a design and analysis of a planar monopole antenna operating in multiband frequencies of 2000 MHz, 2500 MHz and 3500 MHz for use in 3G and 4G mobile devices. Among these bands are contained 3G (1895-2165 MHz), 4G (2500-2690 MHz) and 4G (3400-3600 MHz) spectra used by LTE and WIMAX 3.5. For the development of this study was taken as reference Hua-Ming Chen’s dual-band antenna designed to operate at ISM systems (1800 MHz), wireless networks and Bluetooth (2400 MHz). The project proposed in this work is a modification in the structure of the dual-band antenna adapted for simultaneous triple resonance frequencies used in 4G mobile networks. To achieve the proposed objective was used to simulate the CST® MICROWAVE STUDIO software based on the Finite Integration method in Domain; the simulations were done in the time domain. After obtaining satisfactory simulated results, a prototype antenna was built to test and measurement; the presented results are consistent with those obtained in the simulation, which validates the proposed method.
