Abstract :
The paper presents an overview on the development of Circular Yagi-Uda and collinear type of antenna. The genetic algorithm is used to optimize the two antenna architecture. The main goal of the article is a comparison of directivity and bandwidth of the two omnidirectional gained type of antennas. The circular Yagi antenna has been analysed as solid and wire model. In our analysis, the method of moments (MoM) is used to compute the current distribution and directivity of the Yagi antenna. Microstrip technology is used for planar collinear monopole antenna and simulation with ground plane has been performed using Ansoft HFSS 3D simulator. Prototypes have been realized and measured.
