Tool/software:
I would like to inform you that we are planning to utilize a miniature PCB Helical Antenna ( 868 MHz) in our Smart Metering NIC Card.
Brief Description of our use case as mentioned below :
-
We will utilize this miniature PCB Helical Antenna on the NIC card (2 Layer PCB) as a Tx & Rx communication with the Gateway for the metering Application.
- NIC Card Position will be Horizontal (Parallel to Earth Plane). Please see the image below only for reference of the PCB Helical Antenna with GND Plane.
-
Yes definitely, the GND plane is not getting sufficient for this PCB helical Antenna.
-
PFA the images for PCB Helical Antenna with GND Plane & Placement of Helical Antenna inside the plastic enclosure of the meter
-
-
As seen above image, we are getting GND Plane 35x35 mm
on both sides of the PCB
- As seen above images, We are getting GND plane 35x35 mm
-
Kindly suggest that this GND plane is sufficient for better Antenna efficiency & for obtaining a Gain of approximately 1 dBi. Kindly suggest your feedback
-
For better RF improvement, is it mandatory to provide double-sided GND placement Or Single a single-sided GND placement sufficient?? Please provide your suggestion
- For your information, regarding component placement, we have utilized one side of the PCB, so we need to go to the inner layer to provide the GND plane.

-
In Gateway, Fiber fiberglass whip antenna utilized of 5 dBi Gain & the Antenna works better way omnidirectional in Vertical Polarization.
Let us know if you need more details & provide your email ID for further communication.
Your feedback will be highly appreciated to move forward this project
