The Equilangular Spiral Fed by a Coplanar Microstrip Balun Covering the S, C, X, and K-Bands
There is a requirement to detect signals of interest in a variety of bandwidths over an extremely wide frequency range covering S, C, X, and K bands. In order to accomplish this, an array of antenna elements were designed and fabricated. Due to a span of nearly one decade from the lowest to the highest center frequency, an inherently wide-band cavity backed equiangular spiral antenna design was selected. To allow for miniaturization of the cavity, the spiral was center fed through a coplanar microstrip balun matching network. The antennas radiate right hand circularly polarized (RHCP) far field patterns to counteract cross-polarization effects of the incident electromagnetic field. Furthermore, the RHCP gain was simulated and measured at approximately 8 dBiC with a total 3 dB beam-width in the proximity of 60 degrees for each antenna.
