Dual wideband printed dipole antenna with integrated balun
A printed dipole antenna with integrated balun is presented. The radiating structure is a two-element dipole with resonances at 900 and 1700 MHz, with the balun providing one extra resonance at each band. By co-designing the radiating element with a Marchand balun modified for dual-band operation, an antenna covering the cellular bands 824–960 and 1710–2170 MHz has been achieved. Measurements o...
متن کاملFrequency Triplexer for Ultra-Wideband Systems (6-9 GHz)
A triplexer for ultra-wideband radio implemented entirely with distributed microstrips is presented. The triplexer is composed of a triplex junction network and three bandpass filters. The circuit is integrated in a flex-rigid printed circuit board. Three flat 1 GHz sub-bands in the frequency band 6-9 GHz have been achieved. The group delay variation within each 1 GHz sub-band was measured to b...
متن کاملDual-band and Wideband Design of a Printed Dipole Antenna Integrated with Dual-band Balun
A dual-band printed dipole antenna with integrated balun feed is given in this paper. First, the fork-shaped slot is etched on the arms of the printed dipole antenna to achieve the dual-band operation with resonances at WLAN bands. The radiating element without balun is optimized and operates at 2.4 GHz (2180–2750MHz) and 5.2GHz (5040 MHz–5480MHz) where return loss is less than −10 dB. In order...
متن کاملA Linearity-Improved Ultra-Wideband Balun-LNA for Cognitive Radio
An ultra-wideband low noise amplifier for cognitive radio applications covering 50 MHz to 10 GHz is designed in a 65-nm CMOS technology. A three-stage dc-coupled common source amplifier with RC degeneration at the last stage optimizes the gain, linearity and output gain-phase balancing. Throughout the covered band, the simulated voltage gain is >23.3 dB whereas the noise figure is <3.4 dB. The ...
متن کاملUltra-Wideband Fermi Antenna Using Microstrip-to-CPS Balun
A new design and experimental results of a microstripfed ultra-wideband Fermi antenna at millimeter-wave frequencies are presented. By utilizing a new microstrip-to-CPS balun (or transition), which provides wider bandwidth than conventional planar balun, the design of microstrip-fed Fermi antenna is greatly simplified. The proposed Fermi antenna demonstrates ultra-wideband performance for the f...
