一款基于多物理场调控的超宽带线-圆极化转换器
|
摘要
为了在微波波段实现可调谐的线-圆极化转换器的设计,结合固态等离子体与二氧化钒设计了一种基于多物理场调控的超宽带线-圆极化转换器,通过改变固态等离子体谐振单元激励状态和人为改变外部温度(T)来实现对该线-圆极化转换器工作频段的调控.采用了全波仿真的方法对该极化转换器的极化转换率曲线、反射相位曲线、轴比曲线、表面电流图进行了计算,并讨论了参数r_1与r_3对轴比的影响.仿真结果表明,当固态等离子体区域均未激励且T<68℃时,3 dB轴比频带为14.3—29.7 GHz,相对带宽为70%;当固态等离子体区域均被激励且T<68℃时,3 dB轴比频带为14.4—23.4 GHz与28.6—35.9 GHz,相对带宽分别为47.61%和22.64%;当固态等离子体区域未激励且T≥68℃时,3 dB轴比频带为8.4—11.2 GHz与18.7—29.5 GHz,相对带宽分别为28.57%与44.81%.通过改变固态等离子体的激励状态和外部温度,实现了该超宽带线-圆极化转换器工作带宽向高频和低频区域的移动.
In order to design a tunable linear-to-circular polarization converter in microwave band, an ultrabroadband linear-to-circular polarization converter(LCPC) based on multiphysics regulation is proposed and studied by combining solid state plasma and vanadium dioxide(VO2) in this article. By using the electric control way to control the states of the solid plasma resonator, the solid state plasma can generate excitation and non-excitation state. By using the temperature(T) control way to regulate the phase transition state of the VO2 resonator, the VO2 can generate insulating and metallic state. The purpose of dynamic shift of the proposed LCPC′s operating band can be realized. The polarization conversion rate curve, reflection phase curve,the axial ratio curve and the surface current diagram of the proposed LCPC are analyzed and simulated by the full-wave simulation software HFSS and the effects of parameters r_1 and r_3 on the axial ratio are also discussed.When none of all the solid plasma regions are excited and T < 68 ℃, the presented LCPC is in No. 1 state. On the basis of No. 1 state, if all the solid state plasma are excited, the presented LCPC is in No. 2 state.Similarly, on the basis of No. 1 state, the presented LCPC will be transformed to No. 3 state when T ≥ 68 ℃.The axial ratio band which is less than 3 dB(3 dB AR band) is 14.3-29.7 GHz(the relative bandwidth is 70%)in No. 2 state. The 3 dB AR bands which are 14.4-23.4 GHz and 28.6-35.9 GHz(the relative bandwidths are47.61% and 22.64%) show that the proposed LCPC has the ability to shift the working band to high frequency range. When switching the LCPC to No. 3 state, the 3 dB AR bands which are 8.4-11.2 GHz and 18.7-29.5 GHz(the relative bandwidths are 28.57% and 44.81%) are shifted to low frequency region. Compared with traditional LCPC, our design has the advantages of diverse control means, wide bandwidth, flexible design and strong functionality. At the same time, this LCPC presents a new design method and idea for multiphysical field regulated devices.
