Abstract: A method (300, 400) for communicating RF signals from a mobile station (100). The method can include detecting whether the mobile station or a first antenna (105) of the mobile station is proximate to an object. Responsive to detecting that the mobile station or the antenna is proximate to the object, RF energy being communicated by the mobile station can be distributed among the first antenna and at least a second antenna (110). Distributing the RF energy can include equally distributing the RF energy among the first antenna, the second antenna and/or any additional antennas. Distributing the RF energy also can include unequally distributing the RF energy among the first antenna, the second antenna and/or any additional antennas.

The element has a center point, a first element portion extending away from the center point on a first side of the center point for a first distance in a first direction, bending at a first approximately 180 degree bend, extending towards the center point for a second distance in a second direction, bending at a second approximately 180 degree bend, and extending away from the center point for a third distance in the first direction. The element also has a second element portion provided on a second side of the center point opposite the first element portion on the first side of the center point, the second element portion being substantially a mirror image of the first element portion.

Abstract: A coupled slot probe antenna for use with antenna structures in mobile communication devices, such as cellular telephones and other wireless communication devices. The coupled slot probe antenna includes at least one first conductive element, and a second conductive element coupled between the first conductive element and the printed circuit board (PCB) ground plane of the mobile communication device. The first and second conductive elements define a tunable coupled slot area and the coupled slot probe antenna is coupled to the PCB ground plane in such a way that the coupled slot area is near a low-impedance point of the antenna structure, wherein coupling therebetween improves the bandwidth and the efficiency of the antenna structure. The coupled slot area can be tuned by changing the size of the coupled slot area and by changing the position of the coupled slot area relative to the low-impedance point of the antenna structure.
