This paper presents an ultra-wideband tapered slot patch antenna with bi-directional radiation, reconfigurable for dual band-notched capability and fed by coplanar waveguide. The proposed antenna showed excellent ultra-wideband characteristics with bandwidth of (1.9–12 GHz). In order to reduce the interference of the narrow band communications represented by Worldwide Interoperability for Microwave Access radiation in the range (3.4–3.9) GHz and standard IEEE 802.11a. application (from 5.1 GHz to 6.1 GHz), the antenna was accompanied with adjustable dual-stop band capability in these bands. The dual-band notches are achieved with aid of inserting a parasitic single split ring resonator and etching a single circular complementary circle split ring resonator. The proposed antenna used epoxy (FR4) substrate material with ????r= 4.4 and dimensions of .

AbstractIn this paper, a miniaturized microstrip patch antenna using a negative index metamaterial with modified split-ring resonator (SRR) unit cells is proposed for ultra-wideband (UWB) applications. The new design of metamaterial based microstrip patch antenna has been optimized to provide an improved bandwidth and multiple frequency operations. All the antenna performance parameters are presented in response-graphs. Also it is mentioned that the physical dimensions of the metamaterial based patch antenna are very small, which is convenient to modern communication. A 130 % bandwidth, covering the frequency band of 2.9–13.5 GHz, (for return loss less than or equal –10 dB) is achieved, which allow the antenna to operate in the Federal Communication Commission (FCC) band. In addition, the antenna has a good radiation pattern in the ultra-wide band spectrum, and it is nearly omnidirectional.
