- Abstract
In this study, a simple and compact ultra-wideband (UWB) printed slot antenna with band-notch performance is designed and manufactured. To increase the impedance bandwidth of the square slot antenna, the authors use an S-shaped parasitic structure inside the rectangular slot on the feed line. By using this structure UWB frequency range can be achieved. Additionally, by using square-ring stub with two L-shaped protruded strip inside the square-ring stub, a frequency notched band performance has been obtained. The designed antenna has a small size of 20 × 20 mm², wheeas showing the radiation performance in the frequency band of 3.05 to over 12.76 GHz with a band rejection performance in the frequency band of 5.13 to 6.04 GHz, which has a frequency bandwidth increment of 13% with respect to the previous similar antenna.
