Abstract
Description
This paper aims to analyse radiation pattern for horizontally polarised dual band Yagi-Uda antenna (900/1800 MHz) with the presence of real ground. Simulations were performed at 920 MHz and 1780 MHz and antenna were placed in different distance from the ground. Simulation results of radiation pattern are calculated in the H-plane of the antenna. A
simulation without the ground plane are compared with the result from the one with the real ground. The result shows that the ground plane greatly influences the radiation pattern and increases the gain of H plane significantly.
