High quality-performance by changing parameters of antenna array

Abstract

Several antennas based on cylindrical array and uniform hexagonal array are designed and fabricated on flexible substrate-Teflon. To validate the designed prototypes, the antennas are fabricated and their performance is analyzed. The highlight scheme is to improve the signal performance and electromagnetic field distribution by appropriately changing the parameters of the antennas array, signal frequencies, and steering angles. The proposed antennas array is capable of applying shaping radiation band technique to generate tunable power and radiation domain. The distribution of the field, and the bit-error-rate transmigration coefficient characteristics are measured. The results show that the proposed scheme can achieve better performance by searching the optimal parameters of antenna array.
