Abstract: The present disclosure provides an antenna structure for use in an implantable medical device. The antenna structure includes a first antenna configured to receive wireless signals within a first frequency band, a second antenna configured to receive wireless signals within a second frequency band lower than the first frequency band, and a common output connector. The first antenna includes a first end and a second, free end opposite the first end. The second antenna is connected to the first antenna at a location between the first and second ends. The common output connector is disposed at the first end of the first antenna, and is electrically coupled to the first and second antennas such that signals received by the first and second antennas are output through the common output connector.

Abstract: The present disclosure provides a near field communications (NFC) detector network for use in an implantable medical device. The NFC detector network includes a combined Bluetooth low energy (BLE)NFC antenna, a BLE transceiver, a BLE path electrically connecting the combined BLE/NFC antenna to the BLE transceiver and configured to communicate BLE signals received at the combined BLE/NFC antenna to the BLE transceiver, and an NFC path electrically connecting the combined BLE/NFC antenna to the BLE transceiver, the NFC path configured to generate an activation signal for the BLE transceiver based on an NFC signal received at the combined BLE/NFC antenna.

Abstract: The present invention relates to a vehicle mountable satellite antenna as defined in the claims which is operable while the vehicle is in motion. The satellite antenna of the present invention can be installed on top of (or embedded into) the roof of a vehicle. The antenna is capable of providing high gain and a narrow antenna beam for aiming at a satellite direction and enabling broadband communication to vehicle. The present invention provides a vehicle mounted satellite antenna which has low axial ratio, high efficiency and has low grating lobes gain. The vehicle mounted satellite antenna of the present invention provides two simultaneous polarization states. In one embodiment, a hybrid mechanic and electronic steering approach provides a more reasonable cost and performance trade-off. The antenna aiming in the elevation direction is achieved via control of an electronic beamforming network.
