A radiating element for applying electromagnetic energy to a cavity. The radiating element comprises a feeding section and a grounding section, wherein the feeding section and the grounding section extend substantially within a first plane. The radiating element also includes a radiating section in electrical communication with the feeding section and the grounding section, wherein the radiating section includes at least one bend between the feeding section and a distal end of the radiating section, the at least one bend extending in a second plane different from the first plane.
