This paper presents a design of triangular microstrip antenna with truncated tip and experimentally studied on Ansoft Designer v-2.2.0 software. This design technology is achieved by cutting all three tips of the triangular microstrip antenna and placing a single coaxial feed. Triangular patch antenna is designed on a FR4 substrate of thickness 1.6 mm and(More)
This paper presents a design of Microstrip Patch Antenna Combining Crown and Sierpinski Fractal-Shapes and experimentally studied on IE3D software [10]. This design is achieved by cutting multi shapes in square pattern combined with crown & sierpinski fractal shapes and placing a single coaxial feed. The Sierpinski pre-fractal can be defined by an(More)
The study of microstrip patch antennas has made great progress in recent years. Compared with conventional antennas, microstrip patch antennas have more advantages and better prospects. Different researchers have used different dielectric substrates to fabricate microstrip patch antenna. So a question arises that which dielectric substrate among the common(More)

In this paper a rectangular microstrip patch antenna with a rectangular slot at the left side and a circle embedding in a square slot is proposed. The antenna is resonant at 9 GHz frequency. The antenna is good for directional applications. The antenna can be used for GPS application and for microwave virus sanitizer. The gain of the antenna is 9. 059 dBi.(More)
Edge detection of femur in X - ray images is an important pre processing step in segmentation and 3 - D reconstruction of femur. A typical femur image is generally very noisy. A lot of edges caused by the muscles and other bones can easily mislead the edge detection algorithm. Particularly, the femoral head overlapping the pelvic bone makes it very(More)
