In this paper, microstrip patch antennas with six different shapes i. e. rectangular, circular, square, elliptical, pentagonal and hexagonal are implemented using Ansoft HFSS version 13. 0. 0 software. Antennas are designed on Rogers RT/duroid 5880 material with dielectric constant 2. 2 and thickness 3. 2 mm. The different performance parameters such as return loss, gain and bandwidth of these ...

Abstract A new design of Microsrtip patch fractal antenna for 2.5 GHz is proposed which possess an excellent size reduction possibility with good radiation performance for wireless applications like Wireless Local Area Network (WLAN). The design and simulation results of microstrip patch fractal antenna using Ansoft HFSS is presented which has S11 < -10 dB (VSWR<2). The antenna is designed base...

A novel technique for producing enhanced band width in micro and mm wave region of spectrum is presented.

This study focused on the determination and analysis of an accurate analytical model for PIN diode under different bias conditions. This approach employs analytically derived expressions including the variation of the depletion regions in the device to make the used model available over a wide range of testing conditions without remake the parameters extraction procedure. The validity of the pr...

Patch antennas are one of the most attractive antennas for integrated RF front end systems due to their compatibility with microwave integrated circuits. To fulfill the demand of integrated RF front end systems, a design of microstrip patch antenna with optimum performance at 12 GHz is investigated. It is also investigated how the performance properties of a microstrip patch antenna are affecte...

A probe-fed circularly polarized stacked patch antenna is presented and simulated by using Commercial Ansoft High Frequency Structure Simulator. The design consists of two patches and two substrates. The bottom patch is square-shaped where as the top patch is of triangularshaped. T-shaped slots parallel to the edges of the patches are inserted so that bandwidth can be improved. Enhancement of t...

This paper presents the design and results of a compact tapered U slot UWB printed monopole microstrip antenna. The planar, very small, thin UWB antenna fed by a single 50? microstrip line with truncated ground plane is excited by a coaxial SMA connector. The simulation was done using Ansoft High Frequency Structure Simulator (HFSS) software. Extensive investigations and parametric analysis is ...

This paper deals with the theoretical investigation on a reduced sized Frequency Selective Surface (FSS). The FSS is designed by cutting a unique shaped slot into square patch. It has been shown, how the variation of the dimension of the slot and periodicity results in shifting of resonant frequency . Compared to conventional square patch FSS the designed FSS can provide reduction in resonant f...
