A scanning antenna includes a transmission and/or reception region including a plurality of antenna units and a non-transmission and/or reception region other than the transmission and/or reception region. The scanning antenna includes a TFT substrate, a slot substrate, a liquid crystal layer provided between the TFT substrate and the slot substrate, a seal portion provided in the non-transmission and/or reception region and surrounding the liquid crystal layer, a reflective conductive plate disposed opposing a second main surface of a second dielectric substrate with a dielectric layer interposed between the reflective conductive plate and the second main surface, a first spacer structure defining a first gap between a first dielectric substrate and the second dielectric substrate in the transmission and/or reception region, and a second spacer structure defining a second gap between the first dielectric substrate and the second dielectric substrate in the non-transmission and/or reception region, the second gap being wider than the first gap. The second spacer structure is disposed within the seal portion or within a region surrounded by the seal portion.

Scanning antenna and method for manufacturing scanning antenna

A scanning antenna includes a transmission and/or reception region including a plurality of antenna units and a non-transmission and/or reception region other than the transmission and/or reception region. The scanning antenna includes a TFT substrate, a slot substrate, a liquid crystal layer provided between the TFT substrate and the slot substrate, a seal portion provided in the non-transmission and/or reception region and surrounding the liquid crystal layer, and a reflective conductive plate disposed opposing a second main surface of a second dielectric substrate with a dielectric layer interposed between the reflective conductive plate and the second main surface. The slot electrode includes an opening or a recessed portion formed in the non-transmission and/or reception region and in the region surrounded by the seal portion.

A scanning antenna includes a transmission and/or reception region including a plurality of antenna units and a non-transmission and/or reception region other than the transmission and/or reception region. The scanning antenna includes a TFT substrate, a slot substrate, a liquid crystal layer, a seal portion surrounding the liquid crystal layer, a wall structure (additional seal portion) disposed in a region surrounded by the seal portion in the non-transmission and/or reception region, a reflective conductive plate, a first spacer structure defining a first gap between a first dielectric substrate and a second dielectric substrate in the transmission and/or reception region, and a second spacer structure disposed in the wall structure and defining a second gap wider than the first gap. The wall structure includes a first main side face and a second main side face that intersect a surface of the first dielectric substrate, and at least one of the first main side face and the second main side face includes a plurality of recessed portions and/or a plurality of protruding portions when viewed from a normal direction of the first dielectric substrate.

An antenna with a heater and method for using the same are disclosed. The antenna may comprise: an antenna aperture having a plurality of radio-frequency radiating antenna elements, the antenna aperture having a ground plane and a material for tuning permittivity or capacitance; and a heater structure in thermal contact with the material.

A method and apparatus for testing radio-frequency antenna elements are disclosed. In one embodiment, the apparatus comprises: a frame having a platform to support an array of radio-frequency (RF) antenna elements of a flat panel antenna having antenna elements; a first antenna to transmit microwave energy to subsets of RF antenna elements of the segment and to receive reflected microwave energy from the subsets of RF antenna elements; a filter between the segment and the first antenna, the filter comprising an opening positioned over each of the subsets of RF antenna elements at different times to expose said each of the subsets of RF antenna elements to microwave energy transmitted by the first antenna; a second antenna to receive microwave energy transmitted though the subsets of RF antenna elements at the different times; a controller coupled to the subsets of RF antenna elements and to provide at least one stimulus or condition to the subsets of RF antenna elements; and an analyzer to provide stimulus to the subsets of RF antenna elements and to measure a characteristic of the array using one or both of the first antenna and second antenna.

A method of assembling an antenna aperture from a plurality of antenna aperture segments is described. The method may include placing a first aperture segment relative to a second aperture segment to partially form the antenna aperture. Furthermore, an overlap of the first aperture segment overlaps a complementary underlap of the second aperture segment at a seam. The method may also include joining the overlap of the first aperture segment to the underlap of the second aperture segment to partially form the antenna aperture.

Techniques and mechanisms for providing a low-profile terminal for satellite communication. In an embodiment, a communication terminal includes a radome, an array of radio frequency (RF) elements and a foam layer disposed therebetween. The foam layer includes a first side and a second side opposite the first side, wherein the array of RF elements and the radome are coupled to the foam layer via the first side and the second side, respectively. The communication device provides contiguous structure between the radome and the array of RF elements. In another embodiment, the first side forms a machined surface which contributes to flatness of one or more antenna panels having the array of RF elements disposed therein or thereon.
