AWR1642: EVM board rx antennas

Part Number: AWR1642

Hello, Sir or Madame

 

Sorry to bother you.

 

we are now using your awr1642 EVM board to make our test systems.

I would like to ask a question on the rx antennas. There are total 6 rx antennas on the board. I understand that 4 of them are used for the receivers. The rest two of them (the leftmost and the rightmost) which have the same microstrip patch structure are connected to the ground directly. I would like to know the reason why you put those two antennas there and what the benefits of them are?

 

Thanks, in advanced,

 

Regards,

  • Ling Jin,

    The two outermost antennas are dummy antennas that help improve the radiation pattern and minimize the ripple on the side lobs.
