In this paper, single and dual band EBG structures for wider bandwidth are proposed. In each of the discussed EBGs, a metallic patch of regular geometry is chosen for the unit element. The patch is further modified by cutting slots to get extra inductance and capacitance which results into lower cut-off frequency and larger bandwidth. The proposed EBG structures are compared with the standard m...

In this paper, a dual-band dipole antenna for passive radio frequency identification (RFID) tag application at 2.45 GHz and 5.8 GHz is designed and optimized using HFSS 13. The proposed antenna is composed of a bent microstrip patch and a coupled rectangular microstrip patch. The optimal results of this antenna are obtained by sweeping antenna parameters. Its return losses reach to −18.7732 dB ...

In this article, the theoretical investigations are carried out on slots and notches loaded microstrip patch antenna for dual-band operations. The antenna parameters are calculated such as return loss, VSWR and radiation pattern. It is observed that antenna resonates at three distinct modes of frequencies of 1.490/1.953/2.941 GHz. The characteristics behaviors of the proposed antenna are compar...

This paper proposes a compact printed monopole antenna with dual band-notched characteristics for ultrawideband application. The proposed antenna consist two inverted T-shaped slots in radiating patch, which provides dual band-notched characteristics and partial ground plane with a slit, which provides large usable fractional bandwidth 129% (2.8-13.1 GHz).The upper inverted T-shaped slot provid...

Antenna Miniaturization Using Fractals Richa Garg, AP ECE Deptt., [email protected], J.C.D.C.O.E., Sirsa ABSTRACTThe use of fractal geometry in designing antenna has been a resent topic of interest. Fractal shape has their own unique characteristics that the improved antenna performance can be achieved without degrading the antenna properties. Modern telecommunication system requires antenn...

In this study, a dual-band patch antenna with improved gain and group delay characteristics is proposed for C-band X-band applications in radar satellite communications. the conventional square modified by partially removing ground plane rounding corners. The radius of rounded corners determined parametric study to achieve best performance. According value set 2 mm. Antenna performance analysed...

A compact and planar dual band antenna for wireless communication is presented. The impedance bandwidth of the proposed antenna can cover Bluetooth (2.4–2.484 GHz) and ultrawideband (UWB: 3.1–10.6GHz) bands. It is composed of a semi-bevelled-rectangle patch and a bended L-shaped strip and fed by a microstrip line. The antenna is built on a FR4 substrate with only 21mm × 35mm surface area includ...

Abstract: The purpose of this paper was to design and implementation a single feed, dual frequency ( L1, L2) patch antenna for the Global Positioning System (GPS). The results from the simulation and measurement for this antenna is presented, compared, and used as part of the validation process for the dual frequency, right hand circularly polarized patch antenna designed for GPS L1, L2 operati...

In this article, an analysis of dual band proximity couple stacked microstrip patch antenna has been proposed. The theoretical investigations of antenna parameters such as return loss, gain and radiation pattern are calculated. It is found that antenna resonate at two distinct modes at lower and upper resonance frequencies, i.e. TM01 and TM02. The bandwidths of the proposed antenna are compared...
