摘要： A wideband planar dipole antenna comprises a substrate and two antenna bodies. Metal conductor is printed on the single surface/double surfaces of the substrate to form the antenna bodies. With a dipole antenna architecture, the antenna bodies are manufactured as loop structures similar to concentric circles. The loop structures can be of rectangular or circular shapes. Loops of metal conductors with different lengths resonate to obtain similar but different frequencies. Each path of every antenna body can be finally connected with a metal conductor sheet capable of changing to any shape. Every path can interfere with adjacent paths to achieve the wideband effect. An asymmetric mechanism can be added in one of the antenna bodies. Besides letting the antenna have the resonance effect of the symmetric part, the loop path at the signal source can also be increased to enhance the receiving performance of the antenna.

摘要： A method for reducing memory size and amount of data accessed of a buffered-frame storage device in a video codec is provided. It is applicable to a codec compliant with a video encoding and decoding standard. When a block is decompressed, the block is stored in the buffered-frame storage device using either compression data or reconstructed data based on its encoded mode and the positions of its reference frames, or based on a topological pattern and a pre-determined memory capacity constraint. With this method, not only the memory size of the buffered-frame storage device, but also the computational complexity requirement for decoding compression data of reference frames is reduced. The present invention compromises among the buffered-frame memory size, amount of data accessed, and computational complexity requirement.
