WL1807MOD: WL1807MOD antenna design

Paul Tran

Part Number: WL1807MOD

hi,

i have new design with WL1807MOD, so i have some question about antenna design with this module

- any option for PCB antenna, cause on reference design of TI used CHIP antenna

- With 2 pin antenna RF_ANT1 and RF_ANT2, we need to spear a lot space for placement 2 antenna (Chip antenna ) like TI reference: distance between them bigger than 62.5 and place in 90 degree, so with some small board that too difficult. so question, any idea if we can optimize placement as small as possible

+ Put 2 antenna nearly asap

+ Option use only 1 antenna but our requirement need support 5Ghz and 2.4 GHz, please advise which port that can adapt like that ( from block diagram seem be RF_ANT2 can support , please verify

Hi,

Al the relevant information should be publicly available at the following links:
processors.wiki.ti.com/.../WL18xxMOD_Regulatory_Product_Certification

If you are designing your own antennas you would have to do full certification.
Are you aware of this?

Hi Paul,

For a single antenna design you can refer to our certification page at: processors.wiki.ti.com/.../WL18xxMOD_Regulatory_Product_Certification

Here we list several dual mode antennas that you can use on your design.

for a 2 antenna design the spacing requirement is to avoid one antenna interfering with the other. It is not recommended that you place these antennas close together as performance would be economized.

I hope this helps.

Thanks,
Riz
