Abstract

In order to solve the problem of the stability of the UWB omnidirectional radiation antenna, a three-dimensional bipolar antenna is proposed, which is composed of metal frame with Klopfenstein curve boundary. The antenna is fed with a 50 Ω coaxial line and the reflection coefficient S11 <-10 dB is achieved in the frequency range of 0.45-23.8 GHz. In addition, the H-plane pattern at 22 GHz in the high frequency band remains omnidirectional. The simulation data of the antenna is obtained by CST Microwave Studio® software simulation. The polarization direction of the proposed antenna is only 0.67 times the minimum operating frequency and it has the characteristics of miniaturization and stability of the pattern.
