Abstract
In wireless communication systems, smart antenna is designed to improve radiation in one direction and null out interference in other direction. This can be realized by increasing the directivity of the antenna element which leads to gain in a specific direction. At high frequency, transmission of signals is characterized with impairments. Mitigation of these signal impairments can be accomplished through the improvement of directivity and gain of smart antenna system at terahertz frequency range. This research work proposed and examined smart/ adaptive antennas array at terahertz (THz) frequency range, which can be applied for far distance communications and can be extended to the far-field region of antenna. The adaptive/smart antenna array is appropriately operational in the range of 300 GHz to 3 THz for wireless local area network (WLAN) applications that uses high-frequency (HF) radio waves. The efficiency of this adaptive array antennas system has been optimized and simulated with the aid of commercially available full-wave, Finite Element Method (FEM) based electromagnetic simulator Agilent’s Advanced Design Software (ADS).
