Low profile collinear monopole antenna

Abstract

The paper presents an idea on the development of collinear type of antenna. We intend to provide an original two antenna architecture. The ground plane is taken as dimension 100×100×1.5 mm3 whereas the metal plate has dimension 16.7×1.5×110.5 mm3. The main goal of the article is a comparison of directivity and bandwidth of the proposed antennas. 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. Simulated prototypes have been realized and measured. This class of antenna can be very useful for locationing applications.
