  • Mobile wireless communications device with slotted antenna and related methods
    Patent number: 8698678
    Abstract: A mobile wireless communication device may include a multiple-band antenna on an antenna carrier and connected to a wireless transceiver. The multiple-band antenna may include an elongate base conductor having opposing first and second ends and opposing first and second sides extending between the first and second ends. The elongate base conductor may have a first L-shaped slot with a proximal end opening outwardly at the first side of the elongate base conductor adjacent the first end thereof and having a distal end adjacent a medial portion of the elongate base conductor. The elongate base conductor may have a second L-shaped slot with a proximal end opening outwardly at the first side of the elongate base conductor adjacent the medial portion thereof and having a distal end adjacent the second end of the elongate base conductor. The distal end of the second L-shaped slot may extend closer to the second end of the elongate base conductor than the distal end of the first L-shaped slot.
