In this paper Microstrip antenna using semicircular patch is proposed and ANTENNA DESIGN simulated using HFSS software strip feed is used. microstrip antenna design is to increase the bandwidth and gain (1-14). performance analyses using high frequency structure simulator (HFSS) software. I'm starting with the calculation of design parameter using MATLAB. to get better. patch antenna was analyz...

A novel printed octagonal fractal microstrip antenna with semi-elliptical ground plane is presented for ultra wide band applications. The proposed antenna has a compact size of 20×20×1 mm³. The measured result of the antenna exhibits the ultra wide band characteristics from 2/9 to 14/2 GHz. In this paper, reducing antenna’s size by 35%, the same results were achieved, while small dimension frac...

-This paper presents, method of moments based analysis of broad-wall longitudinal slots array antenna using Multiple Cavity Modeling Technique (MCMT). Theoretical data for reflection coefficient, transmission coefficient, resonance length and resonance conductance have been obtained for two slots in two different waveguide. The theoretical data have been compared with Ansoft HFSS’s simulated da...

In this paper, a tri-band E-shaped microstrip patch antenna is presented for SHF and microwave data links. The proposed antenna has symmetrical properties and has been designed by forming E-shape structure on substrate with Wave guide feed. It radiates for three bands having two bands in SHF and one in lower EHF frequency bands. It is demonstrated that the fabricated antenna offers improved val...

This paper deals with the theoretical investigation on size reduction and wideband operation of Frequency Selective Surface (FSS). The modified FSS has an excellent angular stability performance. The compactness has been achieved by etching out unique types of slot from Square shaped patch. Gradually the dimensions of the slots are modified. At last, in Proposed FSS the size reduction is achiev...

The increasing number of experimental microwave breast imaging systems and the need to properly model them have motivated our development of an integrated numerical characterization technique. We use Ansoft HFSS and a formalism we developed previously to numerically characterize an S-parameter- based breast imaging system and link it to an inverse scattering algorithm. We show successful recons...

This paper deals with single layer polarization independent Frequency selective surface (FSS) which acts as a triple band reject filter. The two stop bands are broad with percentage bandwidth 11.16% and 10.13% and one is narrow with 3.33% bandwidth. The band ratio is more than 1.5 and band separation is around 30-35dB. This design is investigated theoretically by ANSOFT® Designer software and p...

3D printing and printed electronics are combined to demonstrate the feasibility of printing electrically functional RF devices. A combined process is used to demonstrate the feasibility of fabricating a 2.4 GHz antenna in a fully-3D printed object. Both dielectric, which also serves as the structure, and conductors are printed. Full-wave models are generated using Ansoft HFSS. Real-world tests ...
