Antenna design

Is the schematics developed by our engineer for the antenna okay?

1. Is the L6 and 0 ohm resistors are for tuning?

2. Can I remove the 0 ohm resistor and use the same copper track instead of 0 ohm?

Hi Vivek,

The schematic looks good.

1. Is the L6 and 0 ohm resistors are for tuning?

2. Can I remove the 0 ohm resistor and use the same copper track instead of 0 ohm?

L6 is part of the antenna matching network. When the antenna is being tuned the 0 ohm resistor may need to be replaced with a inductor or capacitor in order to tune the antenna impedance to 50Ohm. Replacing L6 with a track removes the option to have a different component there when tuning reducing the options when tuning. Without L6 it may not be possible to tune the antenna to 50Ohm.
