Design and Analysis of Miniaturized Multiband High Frequency Antenna for K and Ka Band Applications

摘要

This paper proposes the design and analysis of co-axial continuous transverse stub multiband antenna (CCTS) for multiple high frequency Applications. Coaxial continuous transverse stub antenna is used to operate on multiple frequency bands with small size and low cost. This proposed antenna consists of two stubs, arranged longitudinally to form a waveguide skeleton like structure. The advantages of CCTS antenna are used to produce omnidirectional radiation pattern in the horizontal plane. This antenna can radiate for the frequency range of 24.5 GHz to 35 GHz which is suitable for portion of K band and Ka band wireless applications. This proposed structure produces very good radiation pattern in both vertical and horizontal plane with minimum acceptable return loss. The simulation software used in this design is CST Microwave Studio and MATLAB.
