Electronic Device With Diverse Antenna Array Having Soldered Connections

摘要

A wireless electronic device may be provided with antenna structures. The antenna structures may be formed from an antenna ground and an array of antenna resonating elements. The antenna resonating elements may be electrically connected to the antenna ground using solder. The antenna resonating elements may be formed from metal traces on a dielectric support structure that surrounds the antenna ground. The antenna ground may be formed form stamped sheet metal and may have slanted steps adjacent to the antenna resonating elements. To form a solder joint between the metal antenna resonating element traces and the sheet metal of the antenna ground, laser light may be applied to the sheet metal of the antenna ground in the vicinity of the solder paste. Separate metal members may also be provided in the vicinity of the solder paste and may be heated using the laser to join metal traces on plastic carriers.
