Hi, In the tutorial you are referring to, a dual-polarized antenna is used for the receiver ( Similarly, in your code, you have set a cross-polarized antenna for both the transmitter and receiver, which explains the observed number of antennas. |

In the published tutorial on Sionna RTX, a single antenna was used for both the transmitter and receiver. When calculating the frequency response of the channel, the shape of h_freq was (1, 1, 2, 1, 1, 14, 48), indicating the presence of two receiving antennas (num_rx_ant = 2). The question arises as to why there are two receiving antennas instead of just one in this scenario.
In my code, I have simulated a single transmit antenna and a single receiver antenna with the corresponding different positions, with the goal of calculating the frequency responses of the channels. However, I am encountering a discrepancy where the number of transmitter antennas is being reported as 2 and the number of receiver antennas is also being reported as 2, and not 1, despite explicitly specifying a single antenna using a panel array with 1 column and a single row.
I tried using sionna.rt.Antenna, but it doesn't seem to work ("TypeError: array must be an instance of AntennaArray").
