brevis gps smd antenna part no. A10204 10 electrical interface 10-1 transmission lines ? 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 (p cb thickness and dielectric constant), a co- planar 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 line is 50 . 10-2 matching circuit the antenna requires a matching circuit that must be optimized for each customer?s product. the matching circuit will require up to three components and the following pad layout should be designed into the device so the correct circuit can be installed: the antenna feed pad and the antenna ground pads are indicated in the drawing above. additional pads are for mechanical attachment only and should not be grounded. integrated antenna and rf solutions 7 product specification 09md-0019-2-ps
brevis gps smd antenna part no. A10204 in addition to the matching circuit, a separate dc blocking capacitor will also be required between the radio and the antenna matching circuit. note: the component values for the matching circuit will vary depending on the size of the pcb and surrounding components. the impedance of the antenna should be measured before selecting suitable matching components. antenova offers this service on request. contact info@antenova.com for further information. 10-3 antenna placement antenna placement locations and orientations are critical for achieving optimal system performance. antenova strongly recommends placing the antenna near the edge of the board. maximum antenna performance is achieved by placing the antenna towards one of the corners of the pcb, with the feed point of the antenna as close to the corner of the pcb as possible. antenova offers a full range of development support to ensure efficient implementation of the antenna into the specific design. to overcome rf design issues, matching circuits, transmission lines, layout and other components, please contact antenova (info@antenova.com) for design and placement recommendations. 10-4 reference board the reference board has been designed for evaluation purposes of the brevis A10204 antenna and it includes a sma female connector dimensions in mm contact info@antenova.com for further details integrated antenna and rf solutions 8 product specification 09md-0019-2-ps
