thick having a relative permittivity of 4.4. A variety of frequency bands, including 2.5, 4.8 and 6.2 GHz, can be used with the antenna. Using HFSS Software, the aerial is simulated, and its effectiveness is assessed in terms of return loss (below -10dB), radiation patterns, and antenna gain. The outcomes demonstrate that the suggested antenna successfully matches impedance and exhibits excellent radiation properties over the desired frequency bands. The proposed antenna offers several advantages, including its multiband capability, compact size, and low cost. It has potential applications in various networks of wireless communication, such as in WLAN, WPAN, and, satellite communication.
