摘要： A dielectric ceramic composition has a dielectric constant, K, of at least 200 and a dielectric loss, DF, of 0.0006 or less at 1 MHz. The dielectric ceramic composition may be formed by sintering by firing in air without a controlled atmosphere. The dielectric ceramic composition may have a major component of 92.49 to 97.5 wt. % containing 60.15 to 68.2 wt. % strontium titanate, 11.02 to 23.59 wt. % calcium titanate and 7.11 to 21.32 wt. % barium titanate; and a minor component of 2.50 to 7.51 wt. % containing 1.18 to 3.55 wt. % calcium zirconate, 0.50 to 1.54 wt. % bismuth trioxide, 0.2 to 0.59 wt. % zirconia, 0.02 to 0.07 wt. % manganese dioxide, 0.12 to 0.35 wt. % zinc oxide, 0.12 to 0.35 wt. % lead-free glass frit, 0.24 to 0.71 wt. % kaolin clay and 0.12 to 0.35 wt. % cerium oxide.

摘要： A novel antenna system for receiving transmissions in the VHF and UHF frequency bands particularly suitable as a miniaturized antenna for UHF reception, such as of digital video broadcasting transmissions. The antenna system utilizes a combination of three techniques including (1) the use of dialect loading using a high dielectric constant ceramic substrate; (2) an antenna dielectrically loaded and tuned to a significantly higher frequency than desired; and (3) use of a tuning circuit to compensate for the frequency offset of the antenna thereby shifting the resonant frequency to cover the entire band. The antenna is intentionally designed to be too small to radiate at the frequency of interest. The antenna element is then ‘forced’ to be tuned to the desired lower frequency using passive (or active) reactive components as part of a tuning circuit. Multi-band operation is achieved by providing a bypass switch to connect the antenna element either to (1) a first receiver without the tuning circuit (i.e. high frequency tuning) or (2) a second receiver with the tuning circuit (i.e. low frequency tuning).

摘要： An interwoven spreading code is formed by a stretched spreading code series at a first frequency and a mirror of the stretched spreading code series at a second frequency. The interwoven spreading code can be used to spread a baseband signal. Data can be recovered through correlation of a received signal with the interwoven spreading code. The spreading code used in forming the interwoven spreading code can be a Barker code.
