A novel compact internal antenna combining a monopole and a parasitic planar inverted‐F antenna type of structure is presented. Based on voltage standing wave ratio <3:1, the operation bandwidths are 42% from 704 to 1083 MHz and 57.7% from 1660 to 3000 MHz to cover LTE700/GSM850/900/DCS1800/PCS1900/UMTS/LTE2300/LTE2500 for mobile phones. The proposed antenna is designed and printed on printed circuit board with compact size of 60 × 15 × 1.2 mm 3 . Measured average low band efficiency is about 60% and high band efficiency is about 70%. The simulated specific absorption rate at required frequency is less than 1.0 mW/g. Both antenna size and performance showed that this antenna has great potential for slim phone applications. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:247–252, 2015
