A planar antenna, such as included as a portion of a wireless communication assembly, can include a dielectric portion, a first conductive portion, extending along a surface of the dielectric portion, and a second conductive portion, parallel to the first conductive portion, extending along the surface of the dielectric portion, the second conductive portion laterally offset from the first portion to provide a specified lateral separation between the first and second conductive portions. The first and second conductive portions can be configured to provide respective resonant operating frequencies ranges offset from each other, and the first and second conductive portions can be configured to follow a commonly-shared path, including at least one bend, along the surface of the dielectric portion.
