Vertical Radiation Patterns of Trunk Mount Antennas for Mobile Radio Communications
Summary :
Theoretical and experimental studies are made in the UHF band on a quarter wavelength monopole and a half wavelength dipole located on a trunk-hood of a car. To calculate vertical radiation patterns, the theoretical model of the car body and the GTD approach are adopted. It is confirmed from a comparison between calculated and measured results that the theoretical model is very useful to analyze the trunk mount antenna performance and the effect of the body can be well examined with it. The results of pattern calculation for two type of antennas show that vertical radiation patterns, especially the pattern in the front direction of the car, depend largely on the car body. That is, many sharp lobes appear in the vertical pattern, and further, the shape of the lobe and the gain vary largely with the change of the antenna height and location. An approach of this kind can be effectively utilized as a design tool to estimate the radiation performance of mobile antennas.
