Improved Performance Analysis of Square Patch Microstrip Antenna at Terahertz Frequency

In this paper improved performance microstrip square patch antenna at terahertz frequency range has been analyzed. The antenna has been designed to radiate at any frequency point in the frequency band of 0.5 to 0.7THz with high gain and radiation efficiency. The effect of various parameters of substrate on radiating patch has been investigated. Gain and radiation efficiency of 21.87 dB and 94.45% have been achieved respectively.
