“…After that apply different DGS method to make a band wideband and is considered Ultra wide band if and only if the bandwidth is greater than 500MHz.Antenna design is done using CST-Microwave Studio 2014 simulation software and the parameters are displayed by the figures. The Ground plane is modified to make the antenna ultra wide band, The Length and Width of Antenna has been calculated by the formula given in books [15], and all the slot cut into the front of the antenna find out by the number of iteration on the simulation software. The ground plane is modified by the different DGS patterns as shown in figures below for the number of iteration the simulation software and dimensions are stored for the best result.…”

“…The SWF of a microstrip line rises when a discontinuity is introduced in the path of the electromagnetic wave which increases the characteristic impedance of the line [8]. The preliminary design parameters of the conventional patch antenna and the reduced antenna using the DMS technique are shown in Table I.…”

This paper presents a new antenna design for passive RFID tags operating at super high frequency band. The proposed antenna includes a cross-array of five elements supporting beam-scanning range over two perpendicular directions. The beam-scanning capability allows the tag to communicate over longer distances without demanding extra power. A matching network between antenna elements and front-end circuitry has also been designed to eliminate phase shift. 3D full-wave electromagnetic simulation results using HFSS CAD tool indicate that the proposed antenna supports 10 dB gain and beam-scanning of more than 180 o over two planes which can be exploited to provide location positioning services.

“…Meanwhile, artificial magnetic conductor (AMC) is a metamaterial which does not exist in nature [14]. Example types of AMC are electromagnetic bandgap (EBG) [15], [16], frequency selective surface (FSS) [17], defected such as defected ground structure (DGS) [18] and defected mircostrip structure (DMS) [19]. Defected structure can be designed at ground and mircostrip feed line, thus the defected structure at waveguide is called DWS.…”

This paper presented the microstrip-fed circular disc monopole antenna with defected waveguide structure. First, the microstrip-fed circular disc monopole antenna was designed. Next, the monopole antenna was designed with waveguide and lastly followed by the defected waveguide structure where the uniplanar compact (UC) structure was used. CST Microwave studio software was used for simulation and parametric studies process. Initially, the microstrip-fed circular disc monopole antenna was designed to achieve return loss less than -10dB for wideband frequencies. Then, the gain and directivity was improved with the integration of waveguide. The highest directivity of 11.38dBi found at 13.5GHz. However, low efficiency and narrower bandwidth were obtained. Next, uniplanar compact defected waveguide structure (UC DWS) was designed at inner surface of waveguide. The bandwidth achieved 3.09GHz where it covered from 10.91GHz to 14GHz. Meanwhile, the directivity maintained higher than the monopole antenna with highest directivity of 8.84dBi at 10GHz. The gain was also improved from 11GHz to 14GHz with highest gain of 6.38dB occurred at 13.5GHz.
