I am having problems with an antenna...

[YingYang22]

I am using this chip (http://mysite.verizon.net/res8dbeh/) and this antenna (http://mysite.verizon.net/res8dbeh/) to build a simple RF receiver that will control a logic circuit. Right now, I have everything on a breadboard and am using a working transmitter to test it out. However, I am not getting anything from the chip.

I checked the ground, Vcc, and address bits to make sure everything was hooked up correctly. It looks like it is, and after talking to the company that makes the chips, they are telling me that the antenna is probably the culprit. Basically, they told me that the chip should be put on a PCB and a decent ground plane should be used to ground the antenna to reduce noise. I am looking to see if anybody can help me get this circuit up and running. Below is what I have so far (messy, I know).

The receiver operates at a very high radio frequency. You cannot use a breadboard at high RF frequencies.
The datasheet says that a perf board (which is much better than your breadboard) "will result in horrible performance and is strongly discouraged".

What are those things that are at each side of the RF receiver? The datasheet says that nothing should be beside the receiver.
The battery is far away so the receiver should have the supply bypass capacitor that is shown in the datasheet.

You need to make a double-sided pcb with a ground plane for this very high frequency receiver.
