Patent ID: 8599088

Claim:
A handheld electronic device comprising: transceiver circuitry; a transmission line coupled to the transceiver circuitry; and an antenna that is coupled to the transmission line, wherein the antenna has a ground plane that has dielectric-filled openings defining a first slot and a second slot, wherein the first slot has a main longitudinal axis, wherein the second slot has a main longitudinal axis, wherein the first and second slots are oriented so that the main longitudinal axis of the first slot is oriented at an angle of between 5° and 85° with respect to the main longitudinal axis of the second slot, wherein the ground plane is configured so that the second slot has a straight portion with a longitudinal axis that is oriented parallel to the main longitudinal axis of the first slot, wherein the second slot has a first width in the straight portion, wherein the ground plane is further configured to define an end portion of the second slot that has a longitudinal axis that is angled with respect to the longitudinal axis of the straight portion of the second slot and that has a second width that is larger than the first width in the straight portion, wherein the second width is perpendicular to the longitudinal axis of the end portion of the second slot, and wherein the end portion is substantially rectangular in shape and has a longitudinal axis that is oriented perpendicular to the longitudinal axis of the straight portion.
