A Wideband CPW-fed Planar Dielectric Tapered Antenna with ... nar dielectric tapered antenna designed for 60 GHz integrated applications fabricated through a novel process compatible with silicon technology. The antenna is composed of ﬁve parts: a CPW line, a balun, a tapered slot line, a dielectric tapered antenna and parasitic elements. Single antenna has a simulated impedance Directional planar spiral antenna - ANTENNASYS, INC. Includes a spiral antenna with feed-point configured to transfer energy to/from the antenna. Includes an energy absorbent backing and an energy absorbent siding coupled with the spiral antenna. Includes a cavity behind the log-spiral slot antenna and in front of the energy absorbent backing. Units by Antenna Type - End Fed Antennas - Balun Designs

How Does it Work? Antennas often require a balanced feed system like the circuit described ... The balun shown in. Figure 1 is intended to be used with a spiral antenna. The CPW-to-CPS .... slot are smaller resonance length and wider bandwidth. [11]. Based on ..... The balun could easily be integrated as part of a microstrip ...

Stripline-based spiral antennas with integrated feed ... 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 ... Patents and Disclosures | John L.
