| Regarding the antennas of broadband radio fuze system as research background, we study the compact and broadband technology of microstrip antennas in this paper, and design the compact and broadband microstrip antennas used in radio fuze system. We choose a project with loaded annual ring microstrip antenna, and the character of compact and broadband is achieved by loading a chip-resister to the antenna. The antenna is analysed by the software based on MOM. The results of simulation and measurement indicate that the antenna designed in this paper has advantages of broadband and compact size, and it is suitable for broadband radio fuze system. |
