Why are the antenna patches arranged like this?
Is it about the virtual array?
Hi Nelson,
The antenna patches are arranged in the above manner to provide the good isolation (/less coupling) between antennas. Also, the above antenna pattern results in solid virtual array pattern as shown below which helps in providing similar performance in both azimuth and elevation regions.
Thanks and Regards,

I'm curious about the arrangement of the antenna patch.
Why not use 1x4 and 4x1 like the drawing below to achieve the same virtual array?
Is there any specific reason?
Hi Nelson,
In the antenna pattern you have referred, Rx2 and Rx3 will have two neighboring antennas which will increase the coupling by 3dB, thus reducing isolation. The isolation issue also exists with the Tx2 and Tx3. Hence, we preferred the below pattern on EVM where each antenna has only one adjacent antenna.
Best Regards,
