摘要： A device includes a display and a housing. The housing surrounds the display and has four corners defining portions of an exterior surface of the device. The housing includes a first housing segment defining at least part of a first corner of the four corners and configured to operate as an antenna; a second housing segment defining at least part of a second corner of the four corners; and a third housing segment defining at least part of a third corner of the four corners. The third corner forms part of the housing diagonally opposite the second corner. The housing further includes a non-conductive housing component that structurally couples the first housing segment to another portion of the housing.

摘要： Embodiments presented herein are generally directed to techniques that provide a medical device component with the ability to communicate in both the near-field and far-field via a single antenna arrangement. More specifically, a medical device component includes an electronics circuit, a coil driver, an antenna arrangement, and an isolation circuit. The isolation circuit operates to extract far-field signals received at the antenna arrangement and provide these signals to the electronics circuit. The electronics circuit is protected from near-field signals received at the antenna arrangement via the isolation circuit.

摘要： An antenna apparatus includes a radiator and two feeding branch circuits, where a first feeding branch circuit includes a first feedpoint and a first filter circuit electrically coupled between the first feedpoint and the radiator, and where the first feedpoint is configured to feed a first signal of a first frequency band. A second feeding branch circuit includes a second feedpoint and a second filter circuit electrically coupled between the second feedpoint and the radiator, with the second feedpoint configured to feed a second signal of a second frequency band. The first filter circuit is configured to allow the first signal to pass through and ground the second signal. The second filter circuit is configured to allow the second signal to pass through and ground the first signal.

摘要： An antenna structure includes a ground plane, a first radiation element, a second radiation element, a third radiation element, and a fourth radiation element. A closed slot is formed in the ground plane. The first radiation element has a feeding point. The first radiation element is coupled to a first shorting point on the ground plane. The second radiation element is coupled to a second shorting point on the ground plane. The second radiation element is adjacent to the first radiation element. The third radiation element is coupled to the feeding point. The fourth radiation element is coupled to a third shorting point on the ground plane. The fourth radiation element is adjacent to the third radiation element. The first radiation element, the second radiation element, the third radiation element, and the fourth radiation element are all disposed inside the closed slot.

摘要： An edge enabled void antenna (EEVA) apparatus is provided. The EEVA apparatus includes a conductive plane and a void is created on a geometric perimeter of the conductive plane to form an EEVA. A radio frequency (RF) port is coupled to the void to receive an RF signal. The RF signal excites the conductive plane to induce an electrical current along the geometric perimeter of the conductive plane. The void can cause the electrical current to increase and decrease on the geometric perimeter of the conductive plane, thus causing an electromagnetic wave corresponding to the RF signal being radiated from the EEVA. By forming the EEVA on the geometric perimeter of the conductive plane, it may be possible to enable a well-functioning antenna apparatus with a small effective footprint, thus allowing multiple EEVAs to be provided in a space confined wireless device with sufficient isolation for improved RF performance.

摘要： A telecommunications antenna comprising a plurality of unit cells each including at least one radiator which transmits RF energy within a bandwidth range which is a multiple of another radiator. The radiators are proximal to each other such that a resonant condition may be induced into the at least one radiator upon activation of the other radiator. At least one of the radiators is segmented into capacitively-connected radiator elements to suppress a resonance response therein upon activation of the other of the radiator.
