One of the trends in wireless communicationis that systems require more and more frequency spectrum.Consequently, the demand for wideband antennas increasesas well. For instance, the ultra wideband radio (UWB)utilizes the frequency band of 3.1-10.6 GHz. Such abandwidth is more than what is normally utilized with asingle low-profile antenna. Low profile antennas arepopular because they are integratable on a printed circuitboard. However, the fractional bandwidth is usually anissue for low profile antennas because of the limitedsubstrate height. The monofilar spiral antenna on the otherhand has higher fractional bandwidth, and at GHzfrequencies the physical dimensions of the spiral isreasonable. Furthermore, a study of how spiral dimensionsimpact on antenna gain and standing wave ratio (SWR) wasconducted and presented. Simulated results were comparedwith measurements.
