摘要： An antenna module includes substrates with different normal directions from each other, a radiating element disposed on the substrate, a radiating element disposed on the substrate, a hybrid coupler, and an RFIC. The hybrid coupler includes input terminals (IN1, IN2), and output terminals (OUT1, OUT2). The RFIC is connected to the input terminals (IN1, IN2) and supplies a radio-frequency signal to the radiating elements. The radiating elements are capable of radiating a radio wave in a first frequency band. The radiating element is connected to the output terminal (OUT1), and the radiating element is connected to the output terminal (OUT2). A phase difference between radio-frequency signals to be supplied to the input terminals (IN1, IN2) is adjusted to fall within a range of greater than −90° and less than 90°.

摘要： An antenna module includes a first substrate, a second substrate, a connection member connected between the first substrate and the second substrate, and an FEM disposed on the connection member. A radiating element is disposed on the first substrate. An RFIC for supplying a radio frequency signal to the radiating element is disposed on the second substrate. The connection member transmits radio frequency signals between the RFIC and the radiating element. The FEM amplifies radio frequency signals transmitted between the RFIC and the radiating element. The FEM is disposed at a position between a connecting point with the first substrate and a connecting point with the second substrate on the connection member.

摘要： An antenna module includes a first power feed element and a second power feed element each having a flat plate shape, and a ground electrode (GND) arranged so as to face the first power feed element and the second power feed element. The first power feed element is configured to radiate a radio wave having a first direction as a polarization direction. The second power feed element is arranged between the first power feed element and the ground electrode (GND), and is configured to radiate a radio wave having a second direction as a polarization direction. A frequency of the radio wave radiated from the first power feed element is higher than a frequency of the radio wave radiated from the second power feed element. An angle formed by the first direction and the second direction is greater than 0° and less than 90°.

摘要： An antenna module includes a dielectric substrate, a plurality of antenna elements, a ground electrode (GND), and a conductor wall. The plurality of antenna elements is arranged in the dielectric substrate in an array form in a first direction and a second direction. The ground electrode (GND) is arranged on the dielectric substrate so as to face the plurality of antenna elements. For each antenna element included in the plurality of antenna elements, the conductor wall is arranged along the second direction between the antenna elements adjacent in the first direction but no conductor wall is arranged between the antenna elements adjacent in the second direction. The second direction is a polarization direction of a radio wave radiated from each of the plurality of antenna elements.

摘要： A patch antenna includes a power feeding conductor pattern formed in a dielectric layer, a ground conductor pattern formed on the dielectric layer, a first parasitic conductor pattern and a second parasitic conductor pattern formed in/on the dielectric layer and is not set to have a ground potential. The first parasitic conductor pattern, the power feeding conductor pattern, the second parasitic conductor pattern, and the ground conductor pattern are arranged in this order in a cross section and overlap each other in a plan view. A resonant frequency f1 defined by an opposite-phase mode current flowing through the first parasitic conductor pattern is higher than a resonant frequency f2 defined by an in-phase mode current flowing through the power feeding conductor pattern, and a resonant frequency f3 defined by an opposite-phase mode current flowing through the second parasitic conductor pattern is lower than the resonant frequency f2.

摘要： An irreversible circuit element includes first and second high pass isolators each including first and second center electrodes intersecting with and being insulated from each other on a ferrite to which a direct-current magnetic field is applied with a permanent magnet. One end of the first center electrode is an output port and the other end thereof is an input port, and one end of the second center electrode is another output port and the other end thereof is a ground port. A pass frequency band of the first isolator is higher than a pass frequency band of the second isolator. Respective output portions of the first and second isolators are electrically connected and defined as one output terminal, and a low pass filter LPF is inserted between the output terminal and the output port of the second isolator.

摘要： An antenna module includes feed elements each having a flat plate shape and a ground electrode arranged opposite the feed elements. The feed element radiates a radio wave of a first frequency band. The feed element radiates a radio wave of a second frequency band that is higher than the first frequency band. In a plan view of the feed element, the distance from the center of the feed element to an end portion of the ground electrode in a first direction is shorter than or equal to ½ of a free space wavelength of a radio wave radiated from the feed element. A feed point of the feed element is arranged at a location shifted in a second direction from the center of the feed element, and the second direction is different from the first direction.

摘要： An antenna device is formed by arranging a plurality of radiation elements each radiating a circularly polarized wave in a matrix of three rows and ten columns. The plurality of radiation elements include radiation elements of four types having a positional relationship rotationally symmetric with each other. The plurality of radiation elements are included in a first element group in which radiation elements are arranged in a matrix of three rows and three columns in one end portion side and a second element group in which radiation elements are arranged in a matrix of three rows and three columns in the other end portion side. A first center element disposed at a center of the first element group is an element of a type obtained by rotating a second center element disposed at a center of the second element group by 180 degrees.

摘要： An antenna module includes a dielectric substrate and a radiation element disposed on the dielectric substrate. The dielectric substrate includes a flat portion (131) and a flat portion (130) having mutually different normal directions, and a bent portion connecting the flat portion (131) and the flat portion (130) to each other. The flat portion (131) has a protruding portion partially protruding in a direction toward the flat portion (130) along the flat portion (131) from a boundary portion between the bent portion and the flat portion (131). The flat portion (131) and the bent portion are connected to each other at a position where the protruding portion is not provided in the flat portion (131). At least a part of the radiation element is disposed on the protruding portion.
