- In this work, three different antenna arrays are designed and fabricated to generate three OAM modes [mode 0, mode +1, and mode -1]. The fabricated OAM antenna is compact related to other uniform circular array OAM antenna. The purity of OAM pattern of each mode is also improved to some extent by using of radial orientation array elements.
- Apart from successfully generated the OAM beam, the effect of dimensional parameters like antenna array radius (R) and number of antenna element (N), on directivity pattern and vortex null-width is also analyzed and results have been shown.
- The effect of increasing OAM mode (l = 0 to +4) on the vortex null-width and in absolute directivity is also analyzed and results have been shown.
- The OAM phase for mode 0 to 4 is simulated to study the effect on the purity of OAM phase pattern and maximum possible OAM modes are observed.
- All these results are compared with two other similar kinds of works.
