摘要： Disclosed is a low band dipole that has four dipole arms in a cross configuration, and a simplified cloaking structure to substantially prevent interference with radiated RF energy from nearby high band dipoles. Further disclosed is a feed network and dipole stem balun configuration that power divides and combines two distinct RF signals, without the use of a hybrid coupler, so that the four dipole arms collectively radiate the two RF signals respectively at a +45 degree and −45 degree polarization orientation relative to the orientation of the dipole arms.

摘要： An antenna element including a base plate, a first ground clustered pillar projecting from the base plate, a second ground clustered pillar projecting from the base plate and spaced apart from a first side of the first ground clustered pillar is provided. The ground clustered pillars, the signal ears, and the ground ears can be shapes so that the capacitive coupling between the ears and the pillars is sufficient to allow them to be spaced further apart, thereby reducing the number of elements required in the phased array. In some embodiments, the ground ear can be directly machined with the base plate thereby obviating the need for the ground ear to be overmolded into the base plate with the signal ear. In other embodiments the phased array antenna can utilize elastomeric connectors to further improve the mechanical and electrical reliability of the connections of the phase array antenna.

摘要： A multi-band antenna includes a first radiating element that is configured to operate in a first frequency band, a second radiating element that is configured to operate in a second, different frequency band, and a metamaterial adjusting element that is configured to at least partially reflect the electromagnetic radiation in the second frequency band incident on the metamaterial adjusting element such that the reflected electromagnetic radiation is redirected to at least partially cancel the interference of the first radiating element to the second radiating element.

摘要： The present disclosure provides a low band dipole and a multi-band multi-port antenna arrangement, wherein the low band dipole has four dipole arms, and the four dipole arms are horizontally and mutually perpendicularly placed in a “+” shape and adjacent two mutually perpendicular dipole arms are fed therebetween. The antenna arrangement includes a main reflector, at least one column of low band dipole array disposed on the main reflector, and at least one column of high band dipole array adjacent to the at least one column of the low band dipole array, wherein at least one low band dipole in each column of the at least one column of low band dipole array satisfies the following condition: the low band dipole has four dipole arms, and the four dipole arms are horizontally and mutually perpendicularly placed in a “+” shape, and adjacent two mutually perpendicular dipole arms are fed therebetween to form a +/−45 degree polarization. The multi-band multi-port antenna arrangement solves the problem that the high and low band dipole arms shield each other and reduces the mutual coupling between the high and low band dipoles by adopting the above-mentioned structure of the low band dipole.

摘要： Disclosed is a high performance low cost multiband antenna configuration that has a low band dipole having dipole arms formed of stamped sheet metal with a plurality of inductor structures. The plurality of inductor structures are oriented along a longitudinal axis of the low band dipole arm, and others are oriented orthogonal to the longitudinal axis. The plurality of the inductor structures act as cloaking structures that make the low band dipole substantially transparent to high band RF energy without inhibiting the performance of the dipole in the low band.

摘要： In a 5th generation (5G) or pre-5G communication system for supporting a high data transfer rate, a method of measuring a power of a signal in an electronic device may include obtaining, by at least one sensor, a first voltage of the signal at a first point between a power amplifier and a transmission line, obtaining, by the at least one sensor, a second voltage of the signal at a second point between the transmission line and an antenna, and calculating a power of the signal, based on the first voltage and the second voltage. A length of the transmission line may be based on a wavelength of the signal. The method and corresponding electronic device reduce an error between power to be calculated and power consumed in practice.

摘要： Telemedicine systems and methods are described. In a telemedicine system operable to communicate with a remote operations center, communications can be transmitted/received using a transceiver having an antenna. The antenna can include first and second di-pole antenna elements, the first di-pole antenna element being vertically polarized and the second di-pole antenna element being horizontally polarized. A controller of the system can establish, using the transceiver, a telemedicine session with the operations center using a Transport Morphing Protocol (TMP), the TMP being an acknowledgement-based user datagram protocol. The controller can also mask one or more transient network degradations to increase resiliency of the telemedicine session. The telemedicine system can include a 2D and 3D carotid Doppler and transcranial Doppler and/or other diagnostic devices, and provides for real-time connectivity and communication between medical personnel in an emergency vehicle and a receiving hospital for immediate diagnosis and treatment to a patient in need.
