摘要：
A multiplate antenna is proposed as an antenna with a low profile, light weight, and large bandwidth. By stacking parallel plates in this antenna, several resonances are generated to increase the bandwidth. In this paper, the FDTD method is used to analyze this low-profile multiplate antenna. First, the frequency characteristics of the input impedance, the SWR, and the radiative pattern are derived, and the results are compared with the measured data. From this comparison, it is proved that the present analytical method is effective for antenna evaluation. Next, the radiative pattern and the current distribution on the plates are described. The variations of the fundamental characteristics of the antenna are studied in terms of the location of the short board and the bridge board as the elements of the antenna. It is found theoretically that the short and bridge boards are effective in adjusting the characteristics of the multiplate antenna, such as the bandwidth. The low-profile multiplate antenna has a size reduction ratio of 0.0057 and a bandwidth of 48% with SWR <2.0.
