摘要： An ultra wideband antenna is provided that filters a predetermined frequency signal. The ultra wideband antenna includes a power feeding part that receives a supply of an external electromagnetic energy; a radiator excited by the electromagnetic energy fed through the power feeding part and radiating an electromagnetic wave; and a stub, provided on the radiator in a direction parallel to a direction of an electric field formed by the electromagnetic wave, that intercepts transmission/reception of a predetermined frequency band signal. The length of the stub may be ¼ of a wavelength of the intermediate frequency of the predetermined frequency band to be removed to filter the corresponding frequency band signal. The ultra wideband antenna simplifies the construction of an ultra wideband receiving system with the power loss and noise characteristics of the system improved.

Thus, the invention can be realized without an APLL, a mixer, an FM modulator, and the like, to reduce power consumption and manufacturing cost for the transmitting apparatus. Thus, noise characteristics and security performance can be high, and the wide band-DCSK modulation method can be robust to multi-path.

摘要： A floating gate electrode configuration and process reduces a space critical dimension between adjacent floating gate electrodes while reducing the consumption of a device isolation layer during etching of a dielectric layer overlying the floating gate electrode. The end portions of the floating gate electrode, which is formed separated on a device isolation region, have a step or rounded pattern. In order to realize such a pattern, after a first partial etch of a floating gate electrode material, polymer spacers or silicon nitride spacers are formed along the etched sidewalls. Then, using those spacers as an etching mask, a second etch is performed on the floating gate electrode material to separate the same. Furthermore, after forming polysilicon on the partially etched floating gate electrode material, blanket etching is performed on the polysilicon to form a floating gate electrode having a round pattern of end portions.

摘要： Provided are an on-chip balun, a transceiver using the on-chip balun, and a method for fabricating the on-chip balun. The on-chip balun includes: a first metal winding including a port grounded and a port to which an unbalanced signal is input; a second winding outputting an induced current generated by the first metal winding as two signals having about equal intensity and a phase difference of about 180°; and a ground shield positioned between the first and second metal windings and having a symmetric structure so as to generate a symmetric parasitic capacitance between the ground shield and the second metal winding. The ground shield can be inserted between the first and second metal windings to remove an asymmetrical parasitic capacitance so as to reduce a phase imbalance and a gain imbalance of an output value of the second metal winding. As a result, a highly balanced on-chip balun can be fabricated.
