This letter proposed a filter‐antenna with continuously adjustable center frequency and bandwidth. The proposed filter‐antenna employs a hybrid structure of a microstrip and quarter‐mode substrate‐integrated waveguide (QSIW). The simulation and test results show that the CF of the filter‐antenna can be continuously tuned between 1.35GHz and 1.472GHz, and the 10‐dB BW is continuously tuned between 30 MHz‐104 MHz. The simulated antenna radiation pattern can maintain good stability in the adjustable range.

具有微带线和四分之一模式基片集成波导混合结构的完全可调滤波器天线

这封信提出了一种具有连续可调中心频率和带宽的滤波器天线。拟议的滤波天线采用了微带和四分之一模式基片集成波导(QSIW)的混合结构。仿真和测试结果表明,滤波器天线的CF可以在1.35GHz和1.472GHz之间连续调谐,而10dB BW可以在30 MHz-104 MHz之间连续调谐。模拟天线辐射方向图可以在可调范围内保持良好的稳定性。
