Multiband LTE-A/WWAN Antenna for a Tablet

Abstract

In this paper, an internal multiband antenna is proposed for LTE-A/WWAN wireless applications in tablet computer. The proposed antenna is configured to have two branch radiators. These two branch radiators are a U-shaped driven monopole and a nonuniform wrapped inverted U-shaped monopole. The impedance bandwidths across dual operating bands are 89.7 MHz and 4185 MHz at the LTE-A/WWAN bands. Various techniques, such as branching and parasitic element are used to enhance the antenna's bandwidth, the matching, and the size of the proposed antenna. The antenna is presented on an area of 50 × 15 mm 2. Experimental results of this antenna show nearly omni-directional coverage and stable gain variation across the LTE-A/WWAN bands.

Printed Multiband Monopole Antenna for Smart Energy Meter/Wlan/Wimax Applications

“…Advanced techniques of metamaterial inspired antennas can also help in miniaturization [11,12]. There are a few tablet and laptop embedded antennas available in literature, which are recommended for endusers [13][14][15][16]. Other literature addresses varied designs of monopole antennas [17][18][19][20][21][22][23][24].…”
