Spiral Antenna Cuts Low Profile To 9.4 GHz
An Archimedean spiral antenna features a unique transmission-line approach to achieve a bandwidth of 0.8 to 9.4 GHz in a compact size.
Tiny Spiral Spans 1.4 To 10.0 GHz

Antennas for broadband and multiple-standard communications must provide excellent performance in a small area. While a spiral antenna can provide consistent radiation patterns, the size reduction is often a problem, since the antenna’s design is related to the physical wavelengths of the operating frequencies. Fortunately, a miniaturized arm-width-tapered Archimedean spiral antenna (ATARSA) has been designed that delivers outstanding performance in a size that is dramatically reduced compared to conventional spiral antennas.
