Units by Antenna Type - End Fed Antennas - Balun Designs Balun Designs LLC - When Performance Counts & Quality Matters A Compact Broadband Spiral Antenna Wei Fu of the vertical balun. In order to reduce the size of the spiral antenna, a compact balun is developed which can be integrated into the spiral antenna. This paper presents a dual arm equiangular spiral antenna with embedded chip resistors and a compact balun. Section II explains the configuration of the entire antenna structure. An Introduction of Aperture Coupled Microstrip Slot Antenna Aperture coupled microstrip slot antenna couples the patch antenna with microstripline through an aperture. Introduction: At microwave and millimeter wave frequencies microstrip slot antenna (1) becomes very small & lightweight. In spite of these advantages, it has main disadvantage of back radiation; which limits its use in mobile communication. Journal of Computing::Adaptive Antenna Array Approach in the ...

Performance of an Ultra Wideband Ceramic-Loaded Slot Spiral," Accepted by ...... There are many baluns that could be used to feed the antenna. An integrated.

In this paper we introduce a flexible, side-fed, ultra-wideband, spiral antenna with an integrated microstrip tapered infinite balun operating from 1-5GHz. It was fabricated using Rogers 5880 subtrate and specially coated to prevent oxidization.

This work covers the design and experiment of a finite-ground stripline-based spiral antenna with a Dyson-style balun and feed network (including broadband impedance transformer) that have been integrated into a multi-layer (via-free) structure. The spiral antenna uses the finite grounds of the stripline feed network (including the balun and impedance transformer) as one arm of the spiral, and

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 A Spiral Antenna with Integrated Parallel-Plane Feeding requirements of the low proflle spiral antenna geometry. A spiral antenna with integrated parallel-plane feeding structure is proposed in this paper. The antenna used has obviously improved axial ratio compared to the equiangular spiral antenna at low frequencies. And the traditional balun in the third dimension is moved to the planar plane.
