Slot Spiral Antenna with Dual Dyson Balun Feed,”.

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.

A slot spiral miniaturized antenna is described. The antenna includes a conductive layer formed on a first side of a dielectric substrate. A slot arranged in the form of a spiral curve and having a slow-wave structure is formed in the conductive layer. The antenna also includes a planar balun formed on a second side of the substrate. The balun is in the form of a conductive layer strip ... High-power ultra-wideband spiral antenna arrays - IEEE ... 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 ... Wideband and Dual-Band Design of a Printed Dipole Antenna ...

The Sinuous Antenna

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. US Patent for Slot spiral antenna with integrated balun 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. Impedance matching is performed between the microstrip feed
