Compact balanced embedded antenna

摘要

A planar antenna, such as included as a portion of printed circuit board assembly, can include a balanced configuration comprising a first conductive layer. The first conductive layer can include a first arm having a footprint extending in a first direction and a second arm having a footprint extending in a direction opposite the first direction. The second arm can be sized and shaped to be similar to the footprint of the first arm.

1. A planar antenna, comprising:
a first conductive layer comprising:
a reference conductor;a first arm having a footprint extending in a first direction, the first arm comprising a first conductive strip having a first lateral width and conductively coupled to the reference conductor; anda second arm having a footprint extending in a direction opposite the first direction, the second arm comprising:
a second conductive strip having a second lateral width narrower than the first lateral width, the second conductive strip conductively coupled to the first conductive strip of the first arm at a distal location with respect to a feed location; andone or more conductive strips coplanar with the second conductive strip and conductively coupled to the reference conductor, the one or more coplanar conductive strips located laterally nearby the second conductive strip and respectively extending from the feed location along the second conductive strip and respectively terminating as stubs at the distal location; wherein the second arm is sized and shaped to be similar to the footprint of the first arm.
