In this paper, the new tapered profile of TSA, which can
operates in WLAN applications, is proposed. By using
squared cosine profile, the antenna can provides appropriate
characteristics and can candidates with exponential profile of
TSA. The performance of the antenna is verified by
experimental data which is obtained from fabrication and
measurement. The CST microwave studio software is
employed to perform the design and optimization processes.
Parametric studies and radiation characteristics are proposed.
The measured results of the fabricated prototype are compared
with the simulated ones, which show that the antenna can
cover 2.4/5 .2/5 .8 WLAN bands.
