Experimental investigation on a method of lowering the silhouette of conical log-spiral antenna

The experimental investigation was made on a low silhouette conical (LSC) log-spiral antenna, which has an advantage of shorter height compared with a conical log-spiral antenna of similar performance. The LSC antennas were constructed, and such antenna properties as radiation pattern, front-to-back ratio, voltage standing wave ratio (VSWR), and axial ratio were experimentally investigated.
