Slot spiral antenna with integrated balun and feed
Mounted cylindrical dipole with a quarter-wave balun feed. The balun-fed dipole is the first antenna released in Antenna Magus that was validated exclusively with respect to a design fabricated and measured by Antenna Magus engineers. This was done as no published reference with measurements was available.

A slot spiral antenna with a planar integrated balun and feed. The slot spiral is produced using standard printed circuit techniques and comprises a dielectric substrate having a conductive layer which is etched to form the radiating slot spiral. An integrated microstrip feed is included to provide a balanced feed to the slot spiral. A new planar feed for slot spiral antennas - IEEE Journals ... Abstract: A new planar, wideband feed for a slot spiral antenna is presented and tested at VHF frequencies. Radiation pattern measurements are presented to demonstrate the performance and usefulness of this feed. In contrast to most traditional printed spiral antenna designs, the one presented here incorporates a completely planar balun and feed, making it more attractive for conformal ... A NEW PLANAR FEED FOR SLOT SPIRAL ANTENNAS baluns, and large absorbing cavities. The presented slot spiral an-tenna feed integrates the balun into the structure of the slot spiral antenna, making the antenna and feed planar. This greatly simplifies the design and construction of the antenna, in addition to providing repeatable accuracy. It also allows the use of a very shallow reflecting WO1997025755A1 - Slot spiral antenna with integrated balun ... A slot spiral (18) antenna with a planar integrated balun and feed. The slot spiral is produced using standard printed circuit techniques and comprises a dielectric substrate having a conductive layer which is etched to form the radiating slot spiral. An integrated microstrip feed (16) is included to provide a balanced feed to the slot spiral.
