Abstract

In this paper, a different method for designing a new slot antenna with dual band-notched characteristic for ultra-wideband applications is presented. The proposed antenna consists of a square-ring radiating stub with an inverted T-shaped strip protruded inside the ring, a feed-line with an E-shaped strip protruded inside the rectangular slot, and a ground plane with a pair of L-shaped strips protruded inside the extra rectangular slot. In this study, by using a a pair of L-shaped strips protruded inside the slot in the ground plane, additional resonance is excited and hence much wider impedance bandwidth can be produced. By using this modified structure in the ground plane, the antenna provides a wide usable fractional bandwidth of more than 130 % (3.01–15.35 GHz). To generate a single band-notched function, we convert a square radiating patch to a square-ring with an inverted T-shaped strip. Finally, by adding a rectangular slot with a protruded E-shaped strip in the microstrip feed line, a dual band-notched function is achieved. The measured results reveal that the presented dual band-notched slot antenna offers a very wide bandwidth with two notched bands, covering all the 5–6 GHz wireless local area network, 8–8.5 GHz international telecommunication union bands.
