  • Publication number: 20230246333
    Abstract: A multiband loop antenna includes a first, electrically conductive, L-shaped partial structure on a first layer of a printed circuit board. The first partial structure has a first resonant frequency and a feed point of the antenna. The multiband loop antenna includes a second, electrically conductive, L-shaped partial structure on the first layer of the circuit board. The second partial structure is configured for a second resonant frequency. The first partial structure and the second partial structure are capacitively coupled to one another in a coupling region. The multiband loop antenna includes an electrically conductive first reference region. The first partial structure and the second partial structure are disposed on the first layer of the circuit board in such a way that they form a loop together with the first reference region. A household appliance including a communication unit having the multiband loop antenna is also provided.

  • Patent number: 8594071
    Abstract: In order to be able to control the creation of a user channel connection in a communication system using wireless communication between at least one mobile part and one wired part in such a way that a user channel connection is established more quickly upon a connection request indicated by the mobile part or the wired part for the purpose of transmitting user data and, at the same time, due to market requirements, no synchronization pulses are sent by the wired part in the idle state, an initiating device of the communication system (for example, for an incoming call: base station; for an outgoing call: mobile part) sends, from an asynchronous idle state, synchronization pulses (SB) to all available physical resources. Due to the plurality of the sent, available synchronization pulses (SB), rapid synchronization is ensured because the probability is sufficiently increased thereby that a pulse will fall in the search window of a receiver.

  • Patent number: 7269032
    Abstract: A shielding apparatus for EMI-sensitive electronic components, especially for radio transmitting devices and/or radio receiving devices of telecommunication terminals for contactless telecommunication, such as cordless telephones and mobile telephones and similar, which can be constructed without using expensive manufacturing and assembly steps without any extra space requirement. The EMI-sensitive electronic components and/or circuits are arranged on a separate, at least double-layered printed circuit board and are embodied as a printed circuit board module.

  • Patent number: 6781562
    Abstract: A radio transmitter and receiver is provided having an electrically acting antenna body in whose near region a dielectric body is arranged, with the dielectric constant of the dielectric body being varied by at least one control signal to ensure an optimum value for at least one physical variable representing a function of the transmission/reception quality of the radio transmitter and receiver.

  • Patent number: 6753819
    Abstract: A mobile radio transmitting and receiving device with a tunable antenna wherein, in order to provide a transmission/reception capability in different frequency bands, with a virtually constant, stable antenna gain, with the radio transmitting and receiving device, a dielectric body which is mounted such that it can be moved is guided by adjusting part, which are controlled by a control device, in a near area of an antenna body, such that the extent of an overlap of the two bodies in the near area of the antenna body is changed until at least one physical input variable, which represents the reception and transmission quality, reaches an optimum.
