Marko Puupponen has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Antenna system for GSM/WLAN radio operation
    Patent number: 7239889
    Abstract: An antenna system with two antennas provides the possibility to operate at least two different radio communication systems with one radio communication system operating on one single antenna of the antenna system and another radio communication system operating on both antennas of the antenna system wherein the antenna system serves as a diversity antenna system. This kind of antenna system is designed to be employed particularly in small devices with restricted measurements. Especially, an implementation of an antenna system for dual use of GSM/E-GSM/DCS operation and WLAN operation is presented.

  • Switching and connecting arrangement for coupling external and internal antennas with an expansion card
    Patent number: 6941409
    Abstract: A switching and connecting arrangement for coupling external and internal antennas, wherein the arrangement comprises at least a diversity switch arranged on a circuit board for selecting a first antenna or a second antenna. The arrangement also comprises a first integrated antenna switch arranged on said circuit board for selecting a first antenna and connecting it electrically to said diversity switch, wherein the first antenna switch is forced mechanically to select the first external antenna instead of the first internal antenna when it is coupled to said switch, and to select the first internal antenna when disconnected; a second integrated antenna switch arranged on said circuit board for selecting a second antenna and connecting it electrically to said diversity switch, wherein the second antenna switch is forced mechanically to select the second external antenna instead of the second internal antenna when it is coupled to said switch, and to select the second internal antenna when disconnected.
