A dual‐band multiple‐input multiple‐output (MIMO) antenna is presented. The proposed MIMO antenna consists of two elements of meander‐line antenna with an isolation improvement structure located between the two radiating antenna elements. The antennas operate in the 4G long‐term evolution (LTE) (699–798 MHz) band, and Universal Mobile Telecommunications Service (UMTS) (Digital Cellular System (DCS)/Personal Communications Service (PCS)) bands (1920–2170 MHz) with |S11| = −6 dB (voltage standing wave ratio (VSWR) = 3) matching criteria. The measured mutual coupling is lower than −15 and −22 dB at the LTE 700 bands, and UMTS bands, respectively. The diversity performance of the envelope correlation coefficient and the mean effective gain meets the diversity criteria for mobile communications. Total radiation efficiencies range between 60 and 90% over the operating frequency bands. A prototype antenna was fabricated and tested for design verification. The simulated results are in good agreement with the measurements.
