A triple band-notched ultra-wideband (UWB) monopole antenna using a planar electromagnetic bandgap (EBG) design is proposed. The EBG unit cell composed by an Archimedean spiral and inter-digital capacitance demonstrates the notch frequencies. The antenna with EBG cells near the feed line occupies only 30 × 36 mm2 with triple band-rejection characteristics. The three notched bands at 4.2 GHz, 5.2 GHz, and 9.1 GHz can be used in C-band satellite downlink, wireless local area network (WLAN), and X-band radio location for naval radar or military required applications. In addition, the proposed design is flexible to tune different notched bands by altering the EBG dimensions. The parametric analysis is studied in details after placing the EBG unit cells near the feed line to show the coupling effect. The input impedance and surface current distribution analysis are also analyzed to understand the effect of EBG at notch frequencies. The proposed design prototype is fabricated and characterized. A fairly considerable agreement is observed between simulated and measured results.

Wireless communication plays a major role in technology transformation into new dimensions where it require most efficient transreceivers which are basically known as antennas for establishing communication between nodes to node.There are different types of antennas used for regenerating different frequencies for different applications. In satellite communication, in air and space crafts or in missile applications where mass, heaviness, volume,budget, performance etc. are the main requirements to design antennas. Such requirements are fulfilled by the Microstrip Antennas . Microstrip Antennas are designed to meet these specifications and hence are widely used in many applications such as global system for mobile communication (GSM), the global positioning system (GPS), personal communication,etc.. A compact microstrip feed with triple band circular monopole antenna which can operate frequencies ranging over GSM (1.78 to 1.82GHz),Bluetooth (2.4 to2.48GHz) and Ultra wideband (UWB:3.10 to 10.6GHz) bands are designed and investigated for wireless applications.By a generalized circular radiating monopole with destructive ground plane,the UWB frequency operation is achieved. Further proceedings, the central part of the radiating antenna is removed by slotting it and then etching a half wavelength circular arc from the radiating patch antenna to achieve a dual band frequency operation over Bluetooth and UWB.The triple band frequency operation is realized by embedding quarter wavelength parasitic element/strip resonating at 1.8GHz placed at the slotted central position in the radiating patch antenna.In this project triple band circular monopole antenna is designed and simulated using electromagnetic simulation software HFSS(15.0).The implementation of the proposed antenna is done on FR4 dielectric substrate having a dielectric constant of 4.4 and loss tangent of 0.02. The antenna covers the three bands of operation with reflective coefficient <-10dB.The antenna also exhibits stable radiation patterns for entire UWB. As a result,integrated lower frequency bands are achieved.

In this paper, a compact triple band-notched Ultra Wideband (UWB) antenna with sharp band-elimination features and controlled notched bandwidths is proposed and discussed. The design is made up of a rectangular-shaped   patch UWB planar monopole antenna with double collections of band-notched configurations. The band-notched configurations are involved to produce the desired lower and upper stop bands with good frequency selectivity and suitable stop bandwidths. The first notch is realized by using a C-shaped slot etched in the radiating patch in order to eliminate the interference at the WiMAX (3.4 - 3.8 GHz) applications. The second and the third notches are realized together by using a pair of U-shaped resonators that are located beside the feed line in both sides to eliminate the interference with the lower WLAN (5.15–5.35 GHz) and the higher WLAN (5.725–5.825GHz) bands.  Additionally, the bandwidths of the lower and upper stop bands can be control separately by changing the parameters of the band-notched configurations. Furthermore, the suggested triple notched bands UWB antenna is optimized, fabricated, and measured for verification purposes. The measured results are close to the simulated ones.

Abstract A triple band-notched ultra-wideband (UWB) monopole antenna etching novel folded resonator on the radiating patch, ground and between the feeding-line, is presented in this paper. The tri-rejection bands are 5.1–6.1 GHz, 7.6–8.8 GHz and 10.1–10.8 GHz which have covered bands of WLAN and ITU 8 GHz. To analyze the principle of proposed antenna, the simulation of parametric study and distribution of surface current are carried out. The size of antenna is 32 mm×19 mm×1 mm. And the test results are in good agreement with the simulation, which indicate that the antenna is promising for UWB system.

Abstract In this paper, a compact ultra-wideband (UWB) monopole antenna with triple band-notched characteristics is presented. These triple band rejections are produced by inserting the Complementary Co-directional Split-Ring Resonator (CC.SRR) on the radiating element for WiMAX/WLAN (3.4–3.95 GHz/5.35–5.9 GHz) and Electromagnetic Band Gap (EBG) structure in the vicinity of transmission line for X-band satellite communications (6.7–7.7 GHz). The proposed antenna with a total size of 18×20.9×1.63 mm3 has been constructed and tested. An equivalent RLC circuit model is proposed and investigated. The simulated and measured results show that the proposed antenna has an impedance bandwidth (VSWR<2) extanding from 3.05 GHz to 14 GHz with triple notched bands of [3.3–3.9 GHz], [5.25–5.86 GHz] and [6.7–7.7 GHz]. The triple band notched characteristics and the good radiation patterns make the proposed antenna a good candidate for the UWB applications.
