A microstrip patch antenna is designed that have metallic ring coplanar to radiation patch for gain enhancement is proposed. The design forces conversion of the surface wave energy into the space wave energy by the scattering of surface waves from metallic ring. The metallic ring is placed around the metal patch at a distance of d1 from the edges of the metal patch and width of metallic ring is...

In this paper, a probe-fed rectangular microstrip patch antenna with partially reflective superstrate at terahertz frequency (600GHz) has been analyzed and simulated. The analysis of the partially reflective surface shows the highly reflective property of the surface over the wideband of the frequencies. The analysis of a specific configuration (rectangular patch) of partially reflective surfac...

In this paper, modeling and experimentation of a Rectangular Patch Resonator (RPR) covered with a dielectric superstrate are investigated. The RPR criteria are established theoretically and experimentally, to be used in future prospects as an electromagnetic (EM) sensor for the characterization of superstrates. The theoretical model is based on the moment method (MoM) via Galerkin’s approach, i...

This paper presents the simulation, design and implementation of bandpass filters in rectangular waveguides. The filters are simulated and designed by using a numerical analysis program based on the Wave Iterative Method (WIM) called WFD (Waveguide Filter Design) simulation. This simulation program can analyze the electrical network of filters. The sample waveguide filter is designed based on a...

In this paper, a wideband dual segment cylindrical dielectric resonator antenna (CDRA) is proposed for 5 GHz WLAN/WiMAX band. The simulation results for the radiation characteristics of the proposed antenna and the absorbed power distribution in a homogenous bio-medium (muscle layer) in direct contact with the proposed CDRA are reported at different frequencies. The specific absorption rate (SA...

Simple internal multiband monopole antenna with low SAR for most of wireless mobile communication applications is presented in this paper. The proposed antenna is an unequal arms monopole antenna with a meander strip in the other substrate side. The antenna has a simple structure and is sufficiently small in size to be easily fit on the housing of mobile or USB dongle with size 18 × 15 × 0.8mm3...

This paper presents the numerical evaluation of the microwave absorption at 2.4 GHz (ISM band) in a homogeneous rectangular head model. Specific absorption rate(SAR) reduction in the head model is achieved by attaching nickel-zinc spinel ferrite sheet resonating at 2.4 GHz to a mobile phone. RF shields made of ferrite sheets are used to suppress surface currents on the mobile phone. Simulations...

Microstrip antennas have numerous advantages such as small size, low fabrication cost, light weight and can be easily installed in the systems and it finds its applications in various systems like aircraft, satellite and spacecraft. But it has drawback of narrow bandwidth. To overcome this drawback, Microstrip Antennas with Defected Ground structure can be used. In this paper, a microstrip patc...

A Comparative study of rectangular and circular shape microstrip fed patch antennas for bluetooth application is presented in this paper.
