Contetns 4.3. ANTENNA Please perform the antenna design that followed the specifications of the antenna About the signal line between an antenna and a module It is a 50‐ohm line design. (SMA Reverse) Fine tuning of return loss etc. can be performed using a matching network. However, it is required to check "Class1 change" and "Class2 change" which the authorities define then. The concrete contents of a check are the following three points.
Contetns 4.3.2. Antenna Reference Trace Design RF traces from eLR100‐UL‐00 module pads pin 47 and J2 pin 1 to the antenna must be made using micro‐strip traces. This micro‐strip trace must respect the design of the Gerber file associated with the following figures in order to obtain a uniform transmission line with a characteristic impedance of 50 ohms. The reference trace design is shown as the green trace along with the side copper filled with vias on the left side.
