This paper presents an aperture-coupled microstrip antenna, which is operating at dual band of millimeter-wave (mmW) frequencies, 28GHz and 38GHz. The aperture antenna was integrated with multilayer substrate construct on 5-layers Low temperature Co-fiber Ceramic (LTCC) with 5 mils thickness. The driven patch was applied to enhance the bandwidth. The bandwidths using are 9.1 percent at 28GHz and 9...
A new metamaterial with negative permeability is presented in this study. Negative permeability metamaterials are called mu-negative (MNG) metamaterial as well. The transmission co-efficient of this metamaterial shows resonance at a certain frequency in the C-band of microwave frequency range for the z-axis wave propagation. It also exhibits the characteristics of a mu-negative (MNG) metamaterial...
In this paper, an inverted S-shaped multi frequency patch antenna is proposed for X-band applications. The antenna encompasses of two rectangular slots on patch, two elliptical slots on the ground plane and its exciting by a 50 Ω probe feed technique. By employing two rectangular slots which change the rectangular patch as opposite S shaped patch antenna operating in triple resonance frequency is...
In this paper, a compact N shaped dual band patch antenna loaded by shorting pin is designed. The lessening in patch size is achieved by perturbing the surface current path on the edge of a circular patch antenna by two triangular slots which make the patch as N shaped. Dual wideband is achieved by combining two triangular slots and shorting pin. Simulated results which are carried out by Finite Element...
In this paper, the design of microstrip antenna for modern wireless communication is presented. The proposed antenna has a fairly good performance of impedance bandwidth at 2.40 GHz. The antenna is designed on size of 46 × 37 × 1.5 mm3 and fed with 50 Ω microstrip line. Satisfactory performance was obtained by using TLC 30 (TACONIC)substrate, allowing low cost production, Tightly controlled Dk, low...
A novel dual band antenna for Wireless Local Area Network (WLAN) applications is presented. The dual band characteristic is achieved by feeding two different length resonant paths with a 50 Ω microstrip line. The compact antenna only occupies 5.3 × 16 mm2 and promotes wideband characteristic. The bandwidth for lower resonance spans from 2.03 GHz to 2.80 GHz (30.3%) and 4.86 GHz to 6.44 GHz (31.6%)...
