Purpose. Wireless network cards serving different roles have different antenna needs: Wireless Access Point (WAP) cards generally need external antennas with larger gains, client cards often use internal surface-mount antennas, and lab-test cards need both. Because the electronics may be otherwise identical, three separate PCB designs were previously required. The invention addresses this by providing one PCB adaptable to all three uses.
Plain-language scope (per the excerpt). The card comprises a PCB with electronic components and an "adaptable antenna connection structure" supporting connections for one or more internal antennas and one or more RF connectors for external antennas. The PCB includes a removable portion; when removed, it leaves an opening that receives an RF antenna connector (e.g., coaxial or another type). The connector is then electrically coupled to conductive pads on the PCB. Where internal antennas are used instead, surface-mount antennas are constructed on the PCB; a lab card can carry both. A stated important aspect concerns how the removable portion is formed: conductive pads adjacent the removable portion are joined by a conductor formed in/on that portion. The excerpt is truncated at this point ("With the removable portion in place, th…").

What the excerpt does not establish. It does not supply the full claim text, dependent claims, or the complete description (including how the conductor joining the pads is severed, PCB layer details, or connector specifics). It does not identify cited prior-art references or claim scope as allowed. Classification codes, drawings, and the referenced related application US 11/554,501 (US 7,406,344 B2) appear in the record but their content is not given here. Assignments, security interests, and legal status are as listed only; no conclusions about validity or enforceability are drawn.

Assignment history
Inventors, original assignee, and the chain of ownership recorded with the USPTO — including the correspondent attorney who recorded each assignment, since shell-LLC chains often share one repeat-player attorney even when the entity names look unrelated. Surfaces NPE / patent-troll patterns: shell-entity transfers, known asserters in the chain, repeat correspondent fingerprints, pre-litigation assignments, and bankruptcy fire-sales.
Prior art
