Design and Analysis of Miniaturized Multiband High Frequency Antenna for K and Ka Band Applications
Authors: P. Jothilakshmi, S. Raju
Abstract: 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.
