Abstract
In these paper an novel U shape Monopole antenna for multiband application has been designed. The designed antenna resonant at three frequency of 2.8 GHz, 5.8 GHz and 10.8 GHz with an impedance bandwidth of 880 MHz, 2500MHz and 3000MHz respectively. The antenna is highly efficient with an efficiency of more than 80% over the desired resonating bands. Moreover it has omnidirectional radiation pattern with an good directivity. The gain of more than 4 dBi is obtained over the desired resonating bands. The VSWR less than 2 dB obtained over the entire band. The designed antenna is suitable candidate for Spacecraft, WLAN and Satellite communication (X bands)applications.
