Design a Compact Microstrip Patch Antenna on a Center Frequency of GSM Band with DGS for Gain Enhancement
Abstract: In this paper, a compact dual band microstrip patch antenna has been designed on a center frequency of GSM band (800–900 MHz) and (1800–1900 MHz) using the DGS technique. The resonating frequency of this antenna 0.845 and 1.850 GHz, the proposed antenna is designed on an FR4 lossy substrate with dielectric constant 4.3, thickness 1.6 mm and loss tangent 0.02. The main objective of this paper is to increase the …

Augmentation in Parameters of S Band Microstrip patch Antenna using Metamaterial with Varactor Diode
Abstract: In this paper S band rectangular microstrip patch antenna is designed and its parameters like return loss, band width, VSWR, directivity, radiation efficiency and size reduction are analysed. Then a metamaterial structure of “Split rectangular Rings” with thin wire strip is designed such that it exhibits negative permittivity and negative permeability at the same frequency as that of inset fed rectangular microstrip patch antenna. Here “Nicolson ross wear” (NRW) parameters …

COMPARISION OF MICROSTRIP BAND PASS AND BAND REJECT FILTER AT GSM BAND (1850MHz) USING DGS TECHNIQUE
Abstract: ABSTRACT- In microwave communication filters are more essential high frequency component. To improve the insertion loss the DGS technique is used. DGS i.e, (defected ground structure) is a technique where cuts are drawn on ground to impove the results and reduce the size of filters. Band pass and band reject filters are the filters which pass and reject the frequency. A band pass and band reject filter is designed with …

A Compact Sector-slotted Circular shaped Filtenna with Enhanced bandwidth
Abstract: This paper presents the designing, simulation and fabrication of a compact Sector-slotted circular shaped filtenna. A Filtenna is designed by integrating the two-pole Butterworth Bandpass filter and the sector-slotted circular shaped patch antenna. This combination of filter and antenna results into compactness of the microwave components and also enhancing the overall performance of the system. The Sector-slotted circular shaped patch antenna is substituted on second port and second resonator. A …
