Abstract: PURPOSE: A reverse triangle antenna for ultra wide band communications is provided to interrupt the WLAN band by inserting a slot of simple structure into the patch radiator. CONSTITUTION: A patch radiator(13) of reverse triangle transceives a signal on rectangular dielectric substrate(11) of rectangular shape. The first and second ground plane(15a, 15b) have trapezoidal shapes. Both sides of a feeding line(17) are separated from the first and second ground planes to perform the power feed about the patch radiator. The first and second ground planes comprise the top side, the lower side, and the outer inclined plane and the inner inclined surface.

Abstract: A CPW(Coplanar Waveguide) low-pass filter with a broad stop band is provided to suppress a spurious response to less than a predetermined level by coupling a DGS(Detected Ground Structure) resonator. A first low-pass filter(40) is formed on a dielectric substrate and has a low-pass function with a first spurious response characteristic by including a first discontinuous pattern unit at a CPW transmission line. A second low-pass filter(50) is coupled to a rear end of the first low-pass filter on the dielectric substrate and has a low-pass function with a second spurious response characteristic by including a second discontinuous pattern unit at the CPW transmission line. A band stop filter(60) is coupled to a rear end of the second low-pass filter on the dielectric substrate and includes a pair of DGS resonators(54a,54b) having a stop characteristic of a third spurious response frequency band to remove a third spurious response generated in a coupling structure of the first and second low-pass filters.

Abstract: A wideband bow-tie monopole antenna having an improved band rejection characteristic is provided to adjust a coupling degree between first and second slots by adjusting an interval between the first and second slots and heights of third and fourth slots inserted into centers of the first and second slots. A rectangular plate-shaped dielectric substrate(1) is vertically installed on a ground surface. A bow-tie type patch(10) is formed at one side of the dielectric substrate to obtain a wideband radiation characteristic. First and second slots(41,42) are set on the bow-tie type patch at a length of 1/2 lambda of a frequency to be interrupted and positioned in parallel to be spaced apart from each other. A parasite ground surface(20) is formed at one side of the dielectric substrate to contact the ground surface at a lower end portion and spaced apart from the bow-tie type patch at an upper end portion in a semicircle shape to form additive wideband resonance. A feed line(30) is formed at the other side of the dielectric substrate and feeds a center of the bow-tie type patch in an indirect coupling method.
