In this paper, a differential unequal power divider with bandpass response has been for the first time proposed. With suitable design of the inverters' impedances, power dividing ratio of the differential power divider could be assigned and realized. A differential, filtering 4:1 power divider has been realized and measured. Bandwidth of return loss is 8%. The input return loss is better than 15 dB...
This paper presents a new design of planar dipole array antenna (PDAA). Radiated patches are etched on the metallic layer of a double-sided printed circuit board (FR4) to form the PDAA. The two symmetric flags with trapezoid patch are designed on both side of the print circuit board to form the basic dipole element. IE3D software is used to design PDAA. Better parameters are selected to manufacture...
