Abstract
ABSTRACTA small‐size dual‐wideband monopole antenna for the long term evolution (LTE) operation in the tablet computer is presented. The antenna occupies a small ground clearance of 10 × 30 mm2 and is easy to implement by feeding a simple radiating portion through an inductive branch (inductor‐loaded branch) and a capacitive branch (capacitor‐loaded branch). The inductive branch mainly generates the antenna's lower band and leads to decreased resonant size for the antenna, while the capacitive branch is mainly for generating the antenna's higher band. By further aided by a simple matching network, both the antenna's lower and higher bands can have enhanced bandwidths. In this study, the antenna not only occupies a small ground clearance but also has a thin thickness of 3 mm only, and the obtained bandwidths can cover two wide bands of 698–960 and 1710–2690 MHz for the LTE operation. Details of the proposed antenna are presented. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:853–860, 2015
