Copper Clearance Via Antennas for Wireless M2M Applications Product Specification Integra-SR4L049-PS-1.0 Page 13 Integra Part No. SR4L049 11. Electrical Interface 11.1 Transmission Line All transmission lines should be designed to have a characteristic impedance of 50. * The length of the transmission lines should be kept to a minimum. * Any other parts of the RF system like transceivers, power amplifiers, etc, should also be designed to have an impedance of 50 . Once the material for the PCB has been chosen (PCB thickness and dielectric constant), a coplanar transmission line can easily be designed using any of the commercial software packages for transmission line design. For the chosen PCB thickness, copper thickness and substrate dielectric constant, the program will calculate the appropriate transmission line width and gaps on either side of the track, so the characteristic impedance of the coplanar transmission is 50 . 11.2 Matching Circuit The antenna requires a matching circuit that must be optimized for each product. The matching circuit will require up to six components, the following circuit should be designed into the host PCB. Not all components may be required but should be included as a precaution. The matching network must be placed close to the antenna feed to ensure it is more effective in tuning the antenna.

No set distance is set and varies depending on the height of the component. So rather than setting a defined distance a rule can be given. An 8 projection line can be drawn from the base of the antenna. This can then be used to decide the distance a component can be. The example below shows a USB connector placed using this rule. Once it is within the 8 limit the distance is known. . Antennas for Wireless M2M Applications Product Specification Integra-SR4L049-PS-1.0 Page 20 Integra Part No. SR4L049 13.0 Antenna Active Tuning for Smaller GND planes For a host PCB with a length less than 75mm is it suggested to use an active tuning circuit to overcome the BW reduction seen with smaller GND. This can be implemented on a single antenna or diversity solution. An Antenova EVB kit is available with this circuit (SR4L049-EVB-3). The SR4L049-EVB-3 evaluation PCB uses a simple RF switching circuit to select between two component values on the T1(Pin4). In this kit the RF switch used is a Peregrine PE423422.
