Hello,

There are patterns connected to the ground on both side of the Rx antennas.

(Please refer to attached file.)

What is the purpose of this layout ?

Hi User,

The antenna are meant for shielding and are tied to ground.

Hello Akash,

Thank you for your response.

Could you tell me the main noize that you want to reduce with this shield ?

Regards.

Hello user1477721,

These are dummy antennas, they are kept to reduce the mismatch between the 4 receive antennas.
This will help us to improve parasitic matching on the inner receiver antennas (RX2 & RX3) as compared to outer antennas RX1 and RX4.
These dummy antenna elements help in slight gain/ phase mismatch reduction.

Thanks and regards,

Hello CHETHAN,

Thank you for your response.

I could understand the role of dummy antennas.

By the way, Are there reference documents which explains designing and tuning of millimeter wave microstrip patch antenna on TI web site ?

Or is it possible to tell me the detailed documents which explains designing process of series connected patch antenna such as used in IWR1642BOOST ?

Regards,

user1477721,

You could explore various antenna/EVMs for various application from the below link.

Each TI EVM provides layout database which includes antenna. Unfortunately, any custom antenna design is beyond the scope of E2E support.

Alternatively, You may want to explore our partners who develop custom antenna designs depending upon your needs in the same link.

Thanks and regards,
