MIMO Dual Sensing Antenna with Notch Characteristics

Design of MIMO antenna with having notch band characteristics between 2.5 GHz-3.7 GHz and 7.7 GHz-8. 6 GHz in the Ultra-wide band operating range from 2.3 GHz-9.96 GHz. For getting notch bands in UWB frequency bands, parallel stubs are kept in the ground to separate the radiating patch elements. The parallel stubs placed in the ground plane improved isolation to 18 dB. The ECC less than 0.01 at the frequency band and the DG is close to 9.5 dB. As the antenna is designed on the flexible polyimide substrate it undergone for bending analysis for different angles like 30⁰,60⁰ and 90⁰. The prototyped antenna measured results providing good agreement with the simulated once obtained from commercial HFSS tool. The obtained band notching characteristics will object some of the frequency applications like WLAN, WiMAX and X-band satellite communication. (paper)
