Small-Size Triple-Wideband LTE/WWAN Tablet Device Antenna

Author:
Wong, Kin-Lu   Weng, Tseng-Wei  


Journal:
IEEE Antennas and Wireless Propagation Letters


Issue Date:
2013


Abstract(summary):

A small-size tablet device antenna with three wide operating bands to cover the Long Term Evolution/Wireless Wide Area Network (LTE/WWAN) operation in the 698 similar to 960-, 1710 similar to 2690-, and 3400 similar to 3800-MHz bands is presented. The antenna has a planar structure and is easy to fabricate on one surface of a thin FR4 substrate of size 10 x 45 x 0.8 mm(3). The antenna is formed by adding a first branch (branch 1, an inductively coupled strip) and a second branch (branch 2, a simple branch strip) to a coupled-fed shorted strip antenna (main portion), and the two branches are configured with the main portion to achieve a compact antenna structure. The three widebands are easy to adjust and can cover the LTE/WWAN operation, which includes the most commonly commercial LTE bands and WWAN bands (698 similar to 960 and 1710 similar to 2690 MHz) and the LTE 3.5-GHz band (3400 similar to 3800 MHz).
