The paper compares u-shaped and complete monopole antennas, focusing on their performance metrics such as return loss, VSWR, current distribution, and radiation patterns. Monopole antennas are highlighted for their high gain and efficiency, as well as their ability to operate across various frequency ranges, including WLAN and WiMAX bands. The results demonstrate the effectiveness of the u-shaped monopole in achieving good impedance matching and radiation characteristics suitable for communication applications.
