OPTIMIZATION OF 3 AXIS ANTENNA SYSTEM

Abstract: Antenna structure is a supporting system which takes the load of different components it houses and transfers the load to the ground. Antenna structure is subjected to various loads such as self-weight, wind loads and even dynamic loads due to the presence of rotating components in the structure. The design and safety plays an important role because it has to efficiently receive and transfer the radio signals to the target. All physical system vibrates. The frequency at which the vibration naturally occur is called the natural frequency. The deformed shape of the structure at a specific natural frequency of vibration is termed as its normal mode of vibration. Each mode shapes is associated with a specific natural frequency. If the exciting frequency coincides with the natural frequency of the structure, resonance occurs. So the main objective of this work is to find the natural frequency of the structure and to keep it away from the exciting frequency by optimization. Optimization is carried by varying stiffness and mass of the structure.
