| 20100109808 | Switchable Tunable Acoustic Resonator Using BST Material - An acoustic resonator includes a first electrode, a second electrode, and a barium strontium titanate (BST) dielectric layer disposed between the first electrode and the second electrode, where the acoustic resonator is switched on as a resonator with a resonant frequency if a DC (direct current) bias voltage is applied across the BST dielectric layer. The acoustic resonator is also switched off if no DC bias voltage is applied across the BST dielectric layer. Furthermore, the resonant frequency of the acoustic resonator can be tuned based on a level of the DC bias voltage, with the resonant frequency increasing as the level of the DC bias voltage applied to the BST acoustic resonator increases. | 05-06-2010 |
| 20100053007 | TUNABLE DUAL-BAND ANTENNA USING LC RESONATOR - An Inverted-F antenna (IFA) includes a tunable parallel LC resonator physically inserted between two antenna bodies of the IFA structure. The LC resonator is comprised of a tunable capacitor C | 03-04-2010 |
| 20090153431 | Continuously Tunable Impedance Matching Network Using BST Capacitor - An impedance matching circuit employs a variable capacitor, such as a BST capacitor. The bias voltage to the variable capacitor may be adjusted in order to match several different frequencies used with the antenna to the signal source. | 06-18-2009 |
| 20090027292 | Ultra-Wideband Log-Periodic Dipole Array with Linear Phase Characteristics - A log-periodic dipole array system employs a structure for the transmitter and the receiver designed in a way such that they compensate for the non-linear characteristics of each other to realize linear phase characteristics as a pair. Radiation elements on the receiver are positioned with respect to its corresponding transmission line in an order opposite to the positioning of the radiation elements on the transmitter. Although neither the transmitter dipole array nor the receiver dipole array itself has linear phase characteristics, the overall dipole array antenna system can realize linear phase characteristic. The log-periodic dipole array system has the advantages that linear phase characteristics can be obtained without sacrificing high radiation efficiency and gain. | 01-29-2009 |
