A simple tri‐band monopole filtering antenna using multimode resonators is proposed. Two novel microstrip open‐loop multimode resonators and a monopole ring antenna with an open stub are integrated together on the same layer of the substrate. Compared with the traditional monopole antenna, the integration makes the proposed antenna operate at 2.4/5.2/6.5 GHz and realize two radiation zeroes at 2 and 3.3 GHz. It leads to the high selectivity for 2.4 GHz. The measured results, including the reflection coefficient, peak realized gain and radiation pattern agree well with the simulated results.
