摘要：
Characteristic mode theory (CMT) provides valuable guidance to realize the current wave modes and distribution features of a single patch antenna. Despite this fact, the generation of multi-mode OAM beams from single-patch antennae in multiple frequency ranges still requires theoretical guidance. In this paper, CMT is performed to analyze a single patch ring antenna. Then, the corresponding orthogonal degenerate modes of TM41 and TM61 modes are selected and excited through an appropriate feeding mechanism. As a result, the single patch ring antenna can radiate third and fourth-order OAM waves in the frequency ranges of 3.96 GHz and 5.18 GHz, respectively. The proposed antenna is recommended for dual-band WiMAX and WLAN applications with more spectral efficiency.
