Abstract
This paper presents the analysis of the effect of mobile phone cylindrical tower on the antenna radiation pattern by using the uniform geometrical theory of diffraction (UTD) method. Generally, the mobile phone base station antennas are installed on the tower such as single post cylindrical tower, cross-braced tower and others. The antenna is located far from the tower in a few wavelength. In that case, the original antenna radiation pattern in free-space will be distorted by the tower. The reflected and diffracted waves generate the interference in the total field radiation pattern. The ripple of radiation pattern as a function of direction is occurred. This paper focus on the single post cylindrical tower. The antenna radiation pattern of the single dipole and unidirctional corrugated horn antenna located on the single post cylindrical tower will be calculated by using the UTD method. The efficiency of the UTD method in the term of the computational time and accuracy is better than other numerical methods. The computational time comparison will be reported.
