Summary:
A simple monopole antenna for hepta-band LTE/WWAN (824 ~ 960/1710~2690 MHz) Metal-framed mobile handset is proposed. Two slits are applied at the upper part of the metal frame. And the metal frame between slits is used for monopole antenna itself. The proposed monopole antenna structure is simple, slim and it has just one feed-line. For producing multiple resonances, impedance matching methods with lumped elements are used. Shunt chip inductor, chip capacitor matching circuit generates resonant modes at 850 MHz and 1700MHz. Band-stop matching circuit and the coupling effect between the metal frame and the antenna widen the low and high frequency bandwidth respectively. Thus, the proposed antenna covers GSM850, GSM900 (824~960 MHz) and GSM1800, 1900, UMTS2100, LTE2400, 2600 (1710~2690 MHz).
