  • Publication number: 20250015498
    Abstract: An antenna for multi-band communication includes a plurality of radiators which are physically separated from each other. Each radiator is disposed on different planes and is used to jointly function as one or more dipoles. Further, each radiator contributes to resonances at two or more non-overlapping bands. This compact, multi-layered antenna structure is designed for space-efficient operation in multiple frequency bands. It is particularly suitable for portable communication devices with size constraints, as it provides transmit and/or receive capabilities across different bands while occupying minimal space.

  • Publication number: 20240234197
    Abstract: A wafer lift pin system is capable of dynamically modulating or adjusting the flow of gas into and out of lift pins of the wafer lift pin system to achieve and maintain a consistent pressure in supply lines that supply the gas to the lift pins. This enables the wafer lift pin system to precisely control the speed, acceleration, and deceleration of the lift pins to achieve consistent and repeatable lift pin rise times and fall times. A controller and various sensors and valves may control the gas pressures in the wafer lift pin system based on various factors, such as historic rise times, historic fall times, and/or the condition of the lift pins. This enables smoother and more controlled automatic operation of the lift pins, which reduces and/or minimizes wafer shifting and wafer instability, which may reduce processing defects and maintain or improve processing yields.
