I am using ESP8266 (esp-07) in a project. I was facing connectivity/range issues with my old router. So, I am planning to use a PCB antenna with esp. This is how it looks:
Here is the mechanical drawing:
I am wondering whether it will work. I have two reasons to be doubtful:
1) I don't have any knowledge about antenna design. So, I am not sure whether this antenna design is suitable for 2.4 GHz.
2) Antenna might be helpful only while transmitting. So it will work when ESP is trying to send some data to router but will not work when router is trying to send some data to ESP.
I want to know what you guys think. Should I try this out or is it totally worthless? Also, what will be more helpful - using this antenna on ESP or getting a better router itself?
Here is a link to the antenna:
