I have seen two type of antenna . zig zag pcb antenna straight pcb antenna so please give the suggestion ,which is suitable for this applicationen-USTelligent Community 13Mon, 10 Jul 2017 09:10:56 GMThttps://devzone.nordicsemi.com/thread/91916?ContentTypeID=1Mon, 10 Jul 2017 09:10:56 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3e273ecd-e2f9-4963-9849-38979ad36a8fbjorn-spockeli<p>The pros and cons of the two antenna layouts are listed below. It basically boils down to how much space you have on your PCB.</p> <p><strong>¼ Wave PCB Antenna</strong></p> <ul> <li>Easy to implement</li> <li>Easy to tune (length and/or external components)</li> <li>Relatively large</li> <li>Not 50 ohm initially (36ohm at resonance)</li> <li>High bandwidth</li> <li>Best solution if space is not a issue</li> </ul> <p><strong>Meander Antenna</strong></p> <ul> <li>Small, but has less gain</li> <li>Must be tuned (length and/or external components)</li> <li>Lower bandwidth than a ¼ wave antenna</li> </ul><div style="clear:both;"></div>
