Table 1 Optimal transmission coefficients (S21) and total signal-to-interference ratio (SIR) when OAM mode number of the transmitter (Tx) is fixed to lT, the receiver (Rx) position is anchored to (x0, y0) = (0, −24) [mm], and the separation distance between the Tx and Rx is 2 [m].
Tx | Fixed Rx at 18 [GHz] | ||
|---|---|---|---|
S 21 | l R = 0 | l R = +1 | l R = −1 |
lT = 0 | 0 | −21.8 | −14.2 |
lT = +1 | −18.8 | 0 | −19 |
lT = −1 | −12.7 | −21.3 | 0 |
Total SIR | 11.7 | 18.6 | 12.9 |
