The non-existing properties of the metamaterial surfaces can be utilized to improve antenna radiation characteristics. In this article, a design and performance analysis Single Negative (SNG) based is imparted for LTE 46/WLAN Ka-band (like in satellite communication receiving side) applications. unit cell surface exhibits negative permittivity positive permeability; yielding high magnitude refr...

A CPW-fed UWB antenna with WiMAX and WLAN band-notched characteristics is presented in this paper. The proposed antenna is fed by a CPW structure and provides the band-notched characteristics by etching an arc slot on the monopole plate and integrating the antenna with electromagnetically coupled microstrip resonator into a single module. In order to prevent interference problem due to existing...

In Antenna Technology, Electromagnetic Band Gap (EBG) structures are one of the mostly used to improve gain antenna, suppress surface waves and band notching. UWB frequency spectrum more number small bands exists these cause electromagnetic interference, reject such EBG required. Due limited monopole antenna's ground plane, it is required have with in size single two or bands. The simulated res...

Abstract—The study of a planar circular slot antenna for Ultrawideband (UWB) communications is presented. The integration on this antenna of a notch filter, to reduce the possible interferences with the 5GHz WLAN communications, has been discussed in detail. Four different structures, achieved by etching a suitable pattern on the antenna circular stub, have been considered, and their features h...

A double dipole antenna design is proposed for wireless local area network (WLAN) applications. Two parallel dipoles are used to facilitate operation in both the standard WLAN frequency bands (IEEE 802.11b and IEEE 802.11a) simultaneously. The lower band dipole is rhombus shaped and radiates above a planar ground plane, while radiation from the rectangular higher band dipole is directed through...

Abstract—In this paper, we use the concept of stub loadings of planar microstrip antennas to convert a single band antenna into a dual-band antenna used for WLAN. We load a planar triangular monopole (PTM) antenna by combline stubs attached to the edges of patch in order to obtain a second resonance frequency. The simple PTM antenna is first designed to produce the lower resonance frequency and...

this paper presents an e-ring shaped printed monopole antenna for uwb applications with dual notched bands performance. in order to generate single frequency band notch function, we applied a u-ring shaped monopole antenna, and by inserting a rectangular ring in the centre of it an e-ring shaped radiating patch created and a dual band-notch function can be achieved. the measured bandwidth of th...
