In this paper, the tapered slot antenna with squared cosine
profile has been presented. The simulated and measured
results in terms of return loss, radiation pattern and gain have
been compared and analyzed, which show this antenna can
support the 2.4/5 .2/5 .8 GHz WLAN bands and 2.5/5.5 GHz
WiMAX bands. Moreover, the proposed antenna with squared
profile has moderately high directivity and symmetrical
radiation pattern. Therefore, it might be suitable for the
WLAN applications
