Abstract :
The dual-band and broadband characteristics of a certain class of microstrip-fed slot antennas are expanded to a special class of notch antennas, and a single-element dual-band antenna for WLAN applications is developed. The antenna uses a simple feed and matching mechanism and has similar radiation patterns at both bands. The same antenna topology can be used to design single-element wideband antennas by appropriately choosing the location of the feed. A prototype consisting of two such radiators is developed and shown to have a very wide bandwidth (1.85:1) while occupying a small area.
