A Wideband Balun — How Does it Work?
Whenever a balanced antenna (i.e., dipole, loop or spiral) is used, the issue of how to feed the antenna becomes relevant. Because a balanced antenna requires a balanced feed, a balun is needed. A balanced antenna fed by a two-wire transmission line is a balanced system with respect to the lines, provided that the two feed points on the balanced antenna have the same orientation and placement w...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
Dual-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 کاملDual 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...
