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.
