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.

A dual input mobile communication device. The mobile communication device can include a housing having an exterior, the exterior including a first face side and a second face side, the second face side located on an opposite side of the housing from the first face side, a first display disposed on the first face side, a numeric keypad disposed on the first face side, a second display disposed on the second face side, and a text keypad disposed on the second face side. The numeric keypad can be a telephone keypad such as a dual-tone multiple-frequency (DTMF) keypad and text keypad can be a QWERTY keypad, such as a keypad having a layout similar to a typical typewriter-style keyboard. The housing can be a candy bar phone style housing.

A battery powered, portable, wireless communications transceiver device (), has a housing () including a first portion () and a second portion (). The device has a controller and a transmitter coupled to the controller. Using a digital, time-division multiple access protocol, the transmitter transmits messages comprised of packets. The first portion and the second portion are connected by a hinge () allowing the device to be put into an opened position or a closed position. The device has a sensor for detecting whether the housing is in an opened or in a closed position. The controller of the device receives a signal from the sensor regarding the position of the housing. The controller is programmable to respond to the position of the housing and to advantageously spread the transmission of packets of the message over a longer period than prior art methods, when the housing is in the closed position.
