ASSEMBLY CONSIDERATIONS The antenna is designed to support hand or automated assembly. To avoid damage to the part, the reflow/solder guidelines found below should be carefully followed. The antenna is single ended meaning that one pad is electrically connected while the other is for mechanical support only. The antenna terminals are not interchangeable so polarity must be observed during assembly. Hand Soldering This antenna is designed for high-volume automated assembly, however, it may be successfully attached by hand assembly techniques. A hand-solder temperature of 225° or lower should be used. Do not exceed a 10 sec. heating time. Reflow Temperature Profile The single most critical stage in the automated assembly process is the reflow process. The reflow profile below should be closely followed since excessive temperatures or transport times during reflow will irreparably damage the antennas. Assembly personnel will need to pay careful attention to the oven's profile to ensure that it meets the requirements necessary to successfully reflow all components while still meeting the limits mandated by the antennas themselves. REFLOW SOLDERING PROFILE Absolute Maximum Solder Times Hand-Solder Temp. TX +225°C for 10 Sec. Hand-Solder Temp. RX +225°C for 10 Sec. Recommended Solder Melting Point +180°C Reflow Oven: +220°C Max.

LAYOUT CONSIDERATIONS The antenna’s wide bandwidth and good stability allow it to perform well and accommodate differing layout requirements. Despite this, proper layout is vital to ensure correct operation. Improper placement of planes, traces or system components will result in nulls or complete detuning. Failure by the designer to respect and account for these requirements will result in unsatisfactory performance. Ideally the antenna will be mounted on the board in such a way as to allow an unobstructed field of view. The area under the backside of the antenna must be free of components, traces, and planes. Components may be placed to the rear of the antenna in the ground plane counterpoise area. The feed trace from the RF stage to the antenna must be a microstrip trace or coax transmission line and should be kept as short as practical. Two sample layouts and their associated data are illustrated on the following pages. They are intended to be representative and it is not necessary to follow them precisely. They do however, exhibit layout techniques and the differences that occur with differing size PCB’s and layouts. After your own layout is complete the performance of the antenna in your specific product should be carefully checked using tools like a network analyzer. In some cases the size of the product’s PCB, proximity of the case or other factors may make a custom version of the antenna necessary. You may contact Antenna Factor for more information.
