Antenna Module Grounding Component for Isolation

A grounding component is introduced as an intermediary element between the first and second radiators. This grounding component includes a first coupling portion, a second coupling portion, and a first grounding portion that connects to the grounding conductor. The grounding component acts as a mediator to improve isolation between the two radiators, allowing them to be positioned closer together than the conventional quarter-wavelength spacing while maintaining effective isolation.

The patent changes the electrical parameters of the antenna system by introducing a capacitor connected to the grounding component. This capacitor modifies the electrical characteristics and isolation properties of the system, enabling the radiators to be spaced closer together. The parameter change involves adjusting the electrical length and impedance characteristics through the capacitor and grounding component configuration.

The grounding component serves as a critical intermediary structure that enables close spacing of radiators while maintaining isolation. It includes a first coupling portion coupled to the first radiator, a second coupling portion coupled to the second radiator, and a first grounding portion connected to the grounding conductor. This intermediary structure provides the necessary electrical isolation even when the radiators are positioned at distances less than a quarter wavelength apart.

The patent introduces a vertical dimension by incorporating a grounding conductor and a grounding component with a first grounding portion that extends toward the grounding conductor. This three-dimensional configuration allows isolation to be achieved not only through horizontal spacing but also through vertical separation and grounding connections, enabling compact planar arrangements while maintaining electromagnetic isolation.
