Abstract

Abstract

The Theory of Characteristic Modes (TCM) provides the antenna designer with physical insight regarding the antenna operating principles. Based on TCM, this paper analyzes in detail the characteristic modes properties of the several transfigurations of metal ring in a cylinder cavity. These properties give information about the radiation ability of every structure. It is very helpful to choose the very right structure as the desired antenna. This paper also gives an effective feed for the combined Inverse-L mode. The manufactured antenna is measured. The measured results show that the band width is 1.8% for VSWR2, the diameter is 0.260, the height is 0.080, and the measured results agree well with the simulated ones. It is verified that the design method based on TCM is very effective.
