In this paper, we propose a low-profile and small wideband multiple-input multiple-output (MIMO) antenna for laptop device sensor network applications, which includes long term evolution (LTE)/wireless wide area network (WWAN) bands, where operating frequencies are 698–960 and 1710–2690 MHz. The proposed antenna is composed of two subantenns: a monopole antenna and a coupled loop antenna. The proposed antenna has dimensions of 62.8 × 11.8 × 0.4 mm3, good antenna impedance bandwidth, nearly omnidirectional radiation patterns, antenna isolation of −15 dB, and an ECC value of only 0.01. Thus, it is very suitable for the sensor network applications of small LTE/WWAN band laptop devices, including modern commercial LTE (700/2300/2500), WWAN (850/900), process control system (PCS), distributed control system (DCS), and universal mobile tellecommunications system (UMTS) standards.
