Reconfigurable Ultra- Wide Band MIMO Antenna

Abstract

Design of a frequency reconfigurable antenna for mobile devices that operate at ultra wide frequency bands of 2.45(WIFI) 3.1 IMT(2.3 GHz), 3.4 GHz, WLAN 802.11 (2.4 and 5 GHz), 5G sub 6 band (1-6 GHz) and satellite-X band (8-12 GHz). In late time, the interest of Ultra-Wideband (UWB) is expanding in mobile devices, radar innovation and Wireless Personal Area Network (WPAN) applications due to high information rate and channel limit. A few radio wire structures have been proposed to consolidate the high information rate and limit, i.e., Multiple Input Multiple Output (MIMO) based radio wire that give the higher information rate and channel limit. In any case, structuring the reduced reception apparatus, while meeting the business prerequisite of UWB-MIMO framework. One of the most encouraging arrangement is to utilize the organizer microstrip reception apparatuses for accomplishing higher information rates, reduced size, low profile, ease, simple to create, ultra-wide transfer Multi band characteristics have been achieved by variation in length of radiating patch, slots, partial ground and parasitic patches while frequency reconfigurability has been achieved by utilizing RF PIN diodes as switches and switchable frequency bands makes the antenna suitable for wireless devices such as laptop, tablets and future 5G smart-phones. The antenna has been simulated on HFSS 13 and has been fabricated and tested. hence this thesis provides the ultimate solution for the data rate issues in mobile devices by using multiple antenna technique on a same patch. This design is stimulated on HFSS13, tested and fabricated.
