摘要: Two compact planar UWB MIMO antennas for wireless communications are presented. The first antenna, which operates in the 2.3–12 GHz frequency band, has a size of 72 mm × 48 0.76 mm. High port-to-port isolation over whole ultra-wideband is achieved by using an inverted-T stub between elements. second antenna 34 47 1.6 mm, and band from 3.8 to 11.8 GHz. Unlike other designs, radiators reversely parallel placed achieving high two ports. Furthermore, interdigital-like structure, composed stubs strips, been employed enhance both bandwidth. current distributions, S parameters radiation patterns given. results show that, have more than 20 dB ultra-wide operation proposed suitable some portable MEVIO/diversity applications.
