I have some questions about the antenna integrated in 20732S.

(1) What kind of antenna is used? (dipole, monopole, microstrip, etc.)

(2) Where is it placed on 20732S?

(3) Could I have characteristics of the antenna? (gain, radiation pattern, and so on)

(4) Could I have data about effects on human body? (SAR testing, etc.)

Could you submit a CSP case for this and assign it to the same gentleman you are working with on the regulatory issues in Japan.

We have this information internally, but I don't believe it is ready for release to the public.

Let me confirm with the business unit how you should go about making this request.

We have still not decided whether or not the detailed antenna that exists internally can be released to the community.

If there is urgency related to the acquisition of this material, please contact your local Broadcom team and have them set you up with a traditional NDA-based Broadcom engagement.

The document doesn't answer to my question because it doesn't state how near can be other objects without significantly modify the radiation pattern of the module. In our application we have another board that is near the first with the BCM2073xS, but attached in the opposite side with a board-to-board connector. Could this situation affect reception of Bluetooth signals?

We are working with our packaging house to see if this information is available.  Stay tuned.

They said that in general, it's not recommended to place wires or connectors in the orthogonal direction of the module.

However, they also said that they do not have any specific experience in this area.
