    915Mhz Circular Patch RFID antenna

    Do this splitter work? http://www.streakwave.com/Itemdesc.asp?ic=17%2D605&eq=&Tp= As I gone order the second antenna from this website anyway. These RFID systems gone go in hotel storage areas. So not one big expensive system, but multiple smaller less expensive is the goal. We will evently...

    915Mhz Circular Patch RFID antenna

    We already used the Laird you mention, it's OK but not better than Wireless Edge. This is the antenna we are using now. http://store.microcom.us/mt262006trhak.html And is the PCB layout mention in the first post. Would your two antenna system with a comb/switch be superior over the that one...

    915Mhz Circular Patch RFID antenna

    Got the antenna today. Biggest problem is that it's polarized. The tags needs to be held in one direction to work. As the tags are placed random in one big bin, this would not work. Getting two antennas maybe is an option, But M10 does not support dual antenna natively.

    915Mhz Circular Patch RFID antenna

    The RFID reader is a M10 from Skyetek http://www.skyetek.com/ProductsServices/EmbeddedRFIDReaders/SkyeModuleM10/tabid/533/Default.aspx Placing it within a few inches of antenna, so coax pigtail is very short. The tags are these, and they do get very good readings compared to other tags these...

    915Mhz Circular Patch RFID antenna

    What could I do to improve the performance on the PCB antenna? It's 7 and 1/4" across at the widest part. What are the right measurements for this type of design? The center screw is grounded to bottom plate with 1/2" metal-spacer. Narrow 910-920 MHz bandwidth is OK. Uses 1watt amp to provide...
