Abstract: A slot antenna structure for an electronic tag includes a dielectric layer, a conductor layer, a slot area and a capacitance adjustment unit. The electronic tag includes an identification chip. The conductor layer is disposed on the dielectric layer. The slot area is disposed in the conductor layer and includes an open slot, an open end and at least one closed slot. The open end is located at an edge of the conductor layer and extends inwardly to form the open slot for disposing the identification chip. The open slot has two sidewalls, and the two sidewalls have at least one turning point at a bottom portion of the open slot to form the closed slot. The capacitance adjustment unit is disposed on a surface of the dielectric layer different from the conductor layer to correspond to the slot area, thereby generating a capacitance effect.

Abstract: An electronic device includes a first housing, a second housing, an antenna module and a conductive elastomer. The second housing is connected to the first housing. The antenna module includes a circuit board. The circuit board has a first surface and a second surface opposite to each other. The first surface faces the first housing and is provided with an antenna pattern. The antenna pattern includes a radiating portion and a grounding portion. The conductive elastomer is located between the antenna module and the first housing. One end of the conductive elastomer is connected to the grounding portion, and the other end of the conductive elastomer is connected to the grounding plane of the first housing.

Abstract: The disclosure provides an antenna structure including a ground plane, a first coupling antenna and a reference antenna. The first coupling antenna includes a first excitation source connected to the ground plane. The first excitation source is configured to excite a first resonant mode, and the first coupling antenna forms a first zero current area on the ground plane in response to the first resonant mode. The reference antenna includes a second excitation source connected to the ground plane. The second excitation source is configured to excite a second resonant mode, and the reference antenna forms a second zero current area on the ground plane in response to the second resonant mode. The first excitation source is located in the second zero current area, and the second excitation source is located in the first zero current area.
