    Abstract: An electromagnetic wave irradiation apparatus includes a housing having a hollow portion formed inside and an open lower side; a coil-type antenna with a spiral shape in the hollow portion and configured to emit electromagnetic waves; a window coupled to the open lower side of the housing; and a capacitance variation measurement unit configured to measure a capacitance variation of the coil-type antenna. The electromagnetic wave irradiation apparatus may further include a cooling unit configured to cool at least one of the window or the housing. The capacitance variation measurement unit includes a capacitance sensor with one side connected to the coil-type antenna and the other side connected to the ground.

    Abstract: An air interface plane (AIP) of a radio frequency (RF) aperture includes: a circuit board having a first side and a second side opposite the first side; and a matrix of tapered elements arranged on the first side of the circuit board and secured to the circuit board, the matrix of tapered elements cooperating to at least one of receive or transmit an over-the-air RF signal. Suitably, each tapered element of the matrix has: a central hub extending along a longitudinal axis from a hub base which is proximate to the first side of the circuit board to an apex of the tapered element which is distal from the first side of the first circuit board; and a plurality of arms extending from the central hub at the apex of the tapered element, each of the plurality of arms including a first portion that projects the arm radially away from the longitudinal axis and a second portion that projects the arm longitudinally toward the first side of the circuit board.

    Abstract: A heat dissipation system for an antenna assembly for a vehicle is disclosed that provides enhanced heat removal attributes and that provides heat transfer from various components to a heat sink through different heat transfer flow paths to reduce the transfer of heat from high heat producing components to heat sensitive components. Improved heat insulation components can be added to maximize the thermal isolation between heat producing components and to prevent heat transferred from the vehicle into the antenna assembly.

    Abstract: A communication apparatus that includes an antenna array comprising a plurality of antenna elements, a plurality of thermoelectric devices distributed across the plurality of antenna element of the antenna array, each of the plurality of thermoelectric devices covers a different subset of a plurality of subsets of the plurality of antenna elements, and a processor coupled to the antenna array and the plurality of thermoelectric devices. The processor detects variation in power consumption in the plurality of antenna elements of the antenna array on a basis of a change in a performance state of the plurality of antenna elements, and controls the plurality of thermoelectric devices to substantially equalize a temperature associated with the plurality of antenna elements for substantial equalization of the performance state of the plurality of antenna elements, where the plurality of thermoelectric devices is controlled based on the detected variation in the power consumption.
