摘要: Abstract In this paper, a novel compact dual band-notched ultra-wideband (UWB) multiple-input multiple-output (MIMO) antenna of size 22 × 26 × 0.8 mm 3 is proposed for portable devices. The comprises two stepped slot UWB antennas fed by 50 ohms microstrip line, T-shape and narrow slot. Dual band-notches from 5.4 to 5.86 GHz 7.6–8.4 GHz are achieved loading trident-shape strips on line. A used the ground plane enhance impedance matching characteristics minimize mutual coupling above 4 GHz. To improve isolation further at 3–4 GHz, ground. giving good bandwidth ranging 3.1 11.8 GHz with |S 11 | > 10 dB larger than 20 dB in entire operating band except rejected bands. simulation measurement results demonstrate that more suitable device applications.
