In view of the complex requirements of the application environment, considering that the back transmission of PCB antenna will be blocked and the receiving range of cylindrical antenna is wide, an omnidirectional microstrip monopole antenna in S/C band is designed by combining printed circuit board and radiation vibrator;The standing wave ratio (VSWR) is less than 2 between 3.45GHz and 4.75GHz. It is characterized by monopole E-plane pattern, gain variation range of 0.2~2.5DBI and good omnidirectivity.In this paper, the monopole application antenna is designed through full wave and circuit simulation, the best parameters are found, the theory is verified by experiments, and an omnidirectional antenna with good performance is designed. |
