Hello,
I'm working on how the antenna array is designed for 4 chip solution.In my scheme, I used nine transmitting antennas (horizontal antennas )on three chips to measure the horizontal angle,and the remaining three antennas( vertical antennas) are used to measure vertical angles.The horizontal spacing of the nine transmitting antenna is 2*lambda.Tthe Rx antenna spacing of lambda/2 on a single chip . I want to know the following design aspects:
1 How to consider the distance between the receiving antennas on different chips?
2 What is the horizontal and vertical spacing between antennas that measures vertical angles? What is the spacing between the vertical antennas and horizontal antennas?
Thank you,
Steven
