20110025431 | CONFIGURABLE ANTENNA INTERFACE - Techniques for interfacing a set of active elements with an antenna array. In one exemplary embodiment, the active elements include a plurality of signal paths, each signal path including a mixer coupled to a local oscillator (LO) signal having an adjustable phase. When the active elements are to be interfaced with an unbalanced antenna, the phase of the LO signal for each signal path coupled to the unbalanced antenna may be adjusted independently of the other signal paths. When the active elements are to be interfaced with a balanced antenna, the phases of the LO signals for the two signal paths coupled to the balanced antenna are adjusted to differ by π radians from each other. The techniques may be applied in either receiver or transmitter applications to provide a flexible interface between an antenna array and an integrated circuit (IC) without the use of baluns. | 02-03-2011 |

20120203082 | TRANSDERMAL ANTENNA - A transdermal antenna may be partially inserted into a cavity in the body of a mammal to receive wireless data transmissions from devices located within the body and relay the data to devices located outside of the body. The transdermal antenna may include a first antenna which may be inserted inside of the body cavity and receive radio frequency data transmissions from devices located inside the body. The transdermal antenna may conduct the received data transmissions to a relay mechanism located outside of the body using coaxial cables, waveguides or a combination of both. The relay mechanism may relay the conducted data transmissions to a receiver device located outside of the body by using a wire connection, such as a coaxial cable, or a wireless communication link via a transceiver coupled to a second antenna. | 08-09-2012 |
