摘要：

A small-sized (15 mmx30 mm) planar monopole MIMO antenna that offers high-isolation performance is presented in this letter The antenna is miniaturized using inductive coupling within a meander-line radiator and capacitive coupling between a radiator and an isolator High isolation is achieved by a T-shaped stub attached to the ground plane between two radiators, which also contributes to the small size using a folded structure and the capacitive coupling with radiators. The proposed antenna operates for the WLAN band within 2.4 GHz to 2.483 GHz. The measured isolation (S-21) is about -30 dB, and the envelope correlation coefficient is less than 0.1.
