The goal of this paper is twofold: to give a brief review of the latest research progress on electromagnetic modeling of vertical interconnects by using Foldy-Lax multiple scattering technique, to introduce a fast full-wave interconnect simulator, namely Foldy-Lax Via Tool, integrating all the extensions that recently have been made available. The kernel part of this novel approach is a mostly ...
This paper presents the electrically small U-slot loaded circular microstrip patch antenna with Complementary Split Ring Resonator (CSRR). The technique of U slot loading is used for operating antenna in dual band and CSRR technique to make antenna compact and CSRR for compactness is used. The simple circular patch antenna resonates at 5. 71 GHz with return loss of -11. 38 dB. The proposed ante...
A corner cut micro strip patch antenna having H slot with small micro strip line feed is presented here. Different design parameters with their effects are studied using v11 Ansoft HFFS. For the operational frequency of 1.8 GHz(1758-1848Mhz), 3.3Ghz(32853454Mhz) and 4.6Ghz(4600-4748Mhz) VSWR bandwidth nearly 1.38 and return loss bandwidth up to -19.75db has been obtained. H slots and corner cut...
Radio Frequency Micro-Electro-Mechanical-Systems (RF MEMS) based switches are expected to play a key role in the field of microwave switching. Traits like low-loss performance; zero-power consumption and very low inter-modulation distortion have made these switches well suitable for high-performance microwave and millimeter-wave circuits. The design of RF MEMS switches, however, require sophist...
The excitation of the higher-order mode, in rectangular dielectric resonator designed was explored to enhance the antenna gain and detailed elaboration is presented in this paper. The antenna was fed by a 50Ω microstrip line through an aperture cut in the ground plane. Besides avoiding spurious radiation, this feeding technique gives flexibility in controlling the amount of coupling in order to...
With advancement in communication technology over the past decade, there is an increasing demand for miniaturization, cost effective, multiband and wideband antennas. Fractal antenna designs can support in meeting these requirements. Though these antennas provide several advantages but at the same time miniaturization and performance of the fractal antennas can be further enhanced using reconfi...
Swallowable capsule endoscopy is used for non-invasive diagnosis of some gastrointestinal (GI) organs. However, control over the position of the capsule is a major unresolved issue. This study presents a design for steering the capsule based on magnetic levitation. The levitation is stabilized with the aid of a computer-aided feedback control system and diamagnetism. Peristaltic and gravitation...
When a plane wave illuminates an electromagnetic band-gap (EBG) structure, the reflection phase continuously changes from 180° to -180° as the frequency increases. Especially at a certain frequency where the reflection phase is 0o, the surface shows the same property as a perfect magnetic conductor (PMC). The PMC material does not exist in nature, b u t an artificial magnetic conductor (AMC) ca...
In this letter, a technique for enhancement of bandwidth along with gain is proposed here. This article deals with design, modeling and simulation of slotted antenna. A star shaped parasitic patch is introduced in the centre of antenna to improve the gain along with the bandwidth by exciting additional resonances. For enhancing bandwidth, a slotted approach is used in ground of antenna along wi...
The aim of this paper is to study a Novel shaped Compact Frequency Selective Surface in wireless dualband applications as a band reject filter. Two resonating frequencies are obtained at 3.2 GHz and 10.45 GHz in this proposed FSS which cover S band and X band respectively. The FSS is designed by cutting slits and slots in the 22mm x 22mm squareshaped patch keeping same periodicity (24mm x 24mm)...
