Abstract: 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.

Abstract: Radiation electrodes are formed on a dielectric base body of an antenna chip. A capacitive feeding electrode is formed on a first end surface of the dielectric base body. A ground electrode, a feeding circuit connection electrode, feeding lines, a tip electrode, and the like are formed on the top surface of a base member of a substrate. When a first switching element selects the feeding line side, a second switching element is made to enter a conducting state. In this state, the radiation electrodes are capacitively fed. When the first switching element selects the feeding line side, the second switching element is made to enter an open state. In this state, the radiation electrodes are directly fed. In this manner, the directivity direction of an antenna can be switched using a single radiation element.
Abstract translation: 辐射电极形成在天线芯片的电介质基体上。 电容馈电电极形成在电介质基体的第一端表面上。 接地电极，馈电电路连接电极，馈电线，尖端电极等形成在基底的基底部件的顶表面上。 当第一开关元件选择馈电线侧时，使第二开关元件进入导通状态。 在这种状态下，辐射电极被电容性地馈送。 当第一开关元件选择馈电线侧时，使第二开关元件进入打开状态。 在这种状态下，直接供给辐射电极。 以这种方式，可以使用单个辐射元件来切换天线的方向性方向。

Abstract: An antenna module includes a first sub array to a fourth sub array. The first sub array to the fourth sub array have a rectangular substrate. Each of the first sub array to the fourth sub array includes a plurality of radiation electrodes disposed along an extending direction of a long side. The first sub array to the fourth sub array are configured to radiate radio waves of the first polarized wave to the fourth polarized wave, respectively. The first polarized wave is different from the second polarized wave, and the third polarized wave is different from the fourth polarized wave. The first polarized wave is the same as the third polarized wave, and the second polarized wave is the same as the fourth polarized wave.

Abstract: An antenna module includes a radiation element including feeding elements adjacent to each other, a feed wiring, a ground electrode, and a filter circuit. The ground electrode is disposed to face the radiation element. The feed wiring transmits a radio frequency signal from an RFIC to the radiation element. The filter circuit is connected between a feed circuit and the feed wiring. The ground electrode includes a first portion facing the radiation element, and a second portion arranged in a layer at an upper side closer to the radiation element than the first portion. In plan view of the antenna module from a normal direction, i) the second portion is disposed between the two feeding elements, and ii) the filter circuit overlaps the second portion and is disposed in a layer at a lower side than the second portion.

Abstract: An antenna module includes a dielectric substrate, a ground electrode in the dielectric substrate, planar radiating elements, and a peripheral electrode. One radiating element faces the ground electrode. Another radiating element is between the one radiating element and the ground electrode. The peripheral electrode is in a layer of the dielectric substrate between the ground electrode and the other radiating element and electrically connects to the ground electrode. The other radiating element emits a radio wave in a frequency band lower than a frequency band of a radio wave emitted by the one radiating element. The peripheral electrode includes multiple planar electrodes stacked in a first direction in which the one radiating element faces the ground electrode. One planar electrode is in a layer between another planar electrode and the ground electrode. The size of the other planar electrode is less than the size of the one planar electrode.

Abstract: An element assembly has a structure in which insulator layers including first and second insulator layers are laminated in an up-down direction. The first insulator layer is above the second insulator layer. A radiant conductor layer is on an upper surface of the first insulator layer. A first capacitance defining portion includes a first interlayer connection conductor passing through one or more of the insulator layers in the up-down direction. The first interlayer connection conductor is electrically connected to the radiant conductor layer. The radiant conductor layer, a ground conductor, and the first capacitance defining portion define and function as a patch antenna. When the first interlayer connection conductor is electrically connected to the radiant conductor layer, a distance from a lower end of the first interlayer connection conductor to the ground conductor in the up-down direction is shorter than a distance from the radiant conductor layer to the ground conductor in the up-down direction.
