Abstract: We introduce a new type of miniature Bluetooth antenna known as a DC inductive shorted patch antenna (DSPA). It is fabricated as a single layer flex circuit wrapped around a high temperature foam substrate. The DSPA has a low 2.2 mm profile, an electrically small footprint of 9x12.6 mm, and it is surface mountable directly on a metal ground plane. In this paper, we report not only on the electrical performance of this Bluetooth antenna, but we introduce a new packaging concept in which the antenna contains an embedded Bluetooth radio LTCC MCM. The result is an integrated radio and antenna package, which is surface mountable. Antenna performance is reported for the integrated package.
Key Words: Bluetooth antenna, DCL shorted patch antenna, Bluetooth MCM.
