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 .

This research puts forward a design regarding a novel compact bi-directional UWB (1.9–10.6 GHz) tapered slot patch antenna that has dual band-notches characteristics within 3.4–3.9 GHz applicable for WiMax application and 5-6 GHz applicable for WLAN (IEEE 802.11a and HIPERLAN/2 systems). A parasitic quasi-trapezoidal shape single split ring resonator SRR is positioned to secure the first WiMax band-notch to minimize the electromagnetic interference occurring in WiMax band. A single circular complementary split-ring resonator (CSRR) is etched to secure the second band-notch. Simulated and measured results showed a good match, thereby signifying that the proposed antenna is an optimum candidate for UWB communication applications along with the guide lines design to employ the notch bands in the preferred frequency regions.

Simulation Techniques

By using the numerical simulation techniques, the response characteristics of single split-ring resonator (SRR) in a broadband terahertz region are analyzed. We examine the transmission and dispersion characteristics of the SRR and show that there are different resonances while changing the orientations of electric field vector relative to the gap-bearing sides. Two significant resonances corresponding to electric response and magnetic response will be observed while the electric field vector perpendicular to the gap-bearing side, and only one electric resonance occurs when the electric field vector parallel to the same side. This will be a reference to design the possible terahertz metamaterials.

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.
