Printed Slot Antenna, N-Shaped Slot, Protruded L-Shaped Strip, Ultra-Wideband (UWB)摘要
A novel ultra wideband (UWB) printed slot antenna with band-notched performance is designed and manufactured. In order to increase the impedance bandwidth of the slot antenna, we use a rectangular slot with a pair of L-shaped strips protruded inside the slot on the ground plane that with this structure UWB frequency range can be achieved. Additionally, by using an N-shaped slot on the radiating stub, a frequency notch band performance has been obtained. The designed antenna has a small size of 20×20 mm2 while showing the radiation performance in the frequency band of 3.12 to over 14.27 GHz with a band rejection performance in the frequency band of 5.03 to 5.86 GHz. Simulated and experimental results obtained for this antenna show that it exhibits good radiation behavior within the UWB frequency range.
