Simple 2.4Ghz antenna

[joedamato]

Hi,

We need a 2.4Ghz smd antenna, not to emit bluetooth but a in-house protocol we are testing. It will need to fit on a pcb and have good performance, and production ready (low cost enough). Think smartphone/tablet/thin devices.

Ideally, it may be set to lower the emitting range; but that is a bonus.

It should be connectable to an ARM Cortex-A9 cpu via spi or uart (or better?)

The setup, security, message format shall be defined by us. The antenna shall just transmit it.

What is the best product in the NS range that would fit best?

Thanks

I think www.nordicsemi.com/.../nRF24L01P is what I am looking for.

If I am correct, it can be put on a pcb, has a spi interface (to connect to the cpu via a copper trace) and we can submit it the data to send in the air.

Is it what I should buy? or am I mistaken?

You have SCK, MOSI, MISO pins. So do I on the cortex A9. So, I don't see where the problem is actually. Correct me if I am wrong, but your transceiver already has all the logic put together (i am not buying a single 2.4Ghz SMT/SMD antenna, so I just need to put it according to your recommendations on the PCB and that is it. Isn't it? (because this is what I need at the end of the day: short time to market, but without a module.)
