A multi-band folded inverted conformal antenna (101), suitable for use internally within an electronic device (501), facilitates low-profile designs with the multi-band folded inverted conformal antenna (601) extending less than five millimeters above a circuit substrate (102) in some embodiments. The multi-band folded inverted conformal antenna (601) includes planar sections and a slot (407), and is capable of multi-mode operation. For example, one embodiment is configured to operate in a first common mode (401), a differential mode (402), and a second common mode (403), thereby allowing the multi-band folded inverted conformal antenna (601) to operate in a first operational bandwidth, second operational bandwidth, and third operational bandwidth. Portions of the ground plane conductor (103) passing beneath the multi-band folded inverted conformal antenna (101) are selectively removed at areas corresponding to concentrations of electrical charge, thereby allowing a more low-profile design.
