Abstract:
Source radio frequency energy (RF) is coupled wirelessly (no physical contact) between two compound loop (CPL) antennas or one CPL and another type of antenna across a variety of barriers such as plastic, human tissues, glass, and air. The compound coupling interface created between the two antennas is highly efficient in transferring the RF energy from a source antenna to a destination including a CPL antenna. A re-radiating structure including a further CPL antenna or a different type of antenna may be connected on the destination side to completely physically isolate the source side from the destination side. When the destination coupling antenna is removed, the source coupling antenna may operate as an efficient radiator at the desired operating frequencies. Likewise, the destination coupling antenna may operate as an efficient radiator in the absence of the source coupling antenna.
Abstract:
A method of packaging an integrated circuit die (12) includes the steps of forming an array of soft conductive balls (14) in a fixture (30) and flattening opposing sides of the balls. The flattened balls are then transferred from the fixture to a mold masking tape (36). A first side of the IC die is attached to the balls with a die attach adhesive (16) and then wire bonding pads (20) on the die are electrically connected directly to respective balls with wires (22). An encapsulant (24) is formed over the die, the electrical connections, and a top portion of the formed balls. The tape is removed and adjacent, encapsulated dice are separated via saw singulation. The result is an encapsulated IC having a bottom side with exposed balls.
