Abstract

An embodiment generally relates to a wave antenna. The wave antenna includes a grounded substrate and a probe feed configured to be substantially centered within the grounded substrate. The wave antenna also includes a load configured to be a linear distance from the probe feed and a conductor trace configured to connect the probe feed and the load. The pattern for the conductor trace is substantially a spiral and the radiation response of the wave antenna is substantially omni-directional.
