I want to build a coin sized receiver that can operate over a distance of 50 feet. I am interested in using a 2.4 GHz ceramic chip SMD antenna, like the one described here
Ceramic Chip Smd 2.4 Ghz Antenna - Buy Ceramic Chip Antenna,Antenna,Ceramic Antenna Product on Alibaba.com
I also want to build/buy a transmitter, but because the transmitter does not have the same size and power constraints that the receiver has, I am trying to investigate the receiver first, with the goal of then finding a transmitter to suit the receiver. Due to this, I do not yet know the transmitter strength. Is there any way I can ESTIMATE whether the chip antenna will be able to receive over the required distance without knowing the specs of the transmitter?
Can anyone give their opinion on whether this type of chip antenna might be capable of receiving over a distance of 50 feet? (This is an indoor environment) Does this sound reasonable? If so, what kind of transmitter specs would you be looking for?
If not, would there be another option I should look at?
I have also found this XBee chip antenna which is claimed to have a range of 300 feet

This is a little too big, and a lot more expensive for what I have in mind. I just want to use a signal received as an ON command for a connected component, so I am thinking that I do not need to send a lot of data with each transmission.
I have also found lower frequency chip antennas here

These operate on 868 MHz, but are of course larger.
