has been successfully used as a balun applied to feed the antenna [22,25]. Designing a small balun with wideband performance is still a challenging issue. In this paper, a UWB antenna is proposed and fabricated. This antenna consists of an integrated balun and a linear tapered slot antenna. The integrated balun based on a microstrip to slotline A PRINTED CIRCUIT FOLDED DIPOLE WITH INTEGRATED … WITH INTEGRATED BALUN Paul M.

CD z I' a tA z.In Figure 2. Folded Dipole with Integrated Balun ... ab (that is. the open-end length and slot ... High-power ultra-wideband spiral antenna arrays - IEEE … Jan 11, 2014 · The four-arm spiral antenna configuration is considered to ensure a good frequency-domain performance of the good time-domain spiral (i.e. loosely-wrapped spiral). Finally, the four-arm spiral's beamformer complexity is addressed by the development of a dual microstrip feed which acts not only as an integrated balun (infinite Dyson balun), but Flexible Spiral Antenna with Microstrip Tapered Infinite Balun … solution for antenna systems using spiral antennas. The infinite balun used in many papers for spiral (slot) antennas basically consists of a coaxial cable spiraled along the antenna arms with the coaxial shield soldered to the antenna arm. At the center, the coaxial pin connects to the other antenna arm. This balun construction only provides
