Design and Implementation of a Compact Super-Wideband Printed Antipodal Antenna Using Fractal Elements

A compact printed fractal antipodal bow-tie antenna is designed and implemented to simultaneously cover the operations in the C, X, and Ku-bands. It is demonstrated that by addition of small fractal elements at the sides of hexagonal arms of the bow-tie, a wide operating frequency range of 3.3 to 19.1 GHz can be covered while antenna size is only 30×34×1.2 mm3. In order to match the antenna to ...

Computation on Parametric Curves with an Application in Grasping

Curved shapes are frequent subjects of maneuvers by the human hand. In robotics, it is well known that antipodal grasps exist on curved objects and guarantee force closure under proper finger contact conditions. This paper presents an efficient algorithm that computes, up to numerical resolution, all pairs of antipodal points on a simple, closed, and twice continuously differentiable plane curv...

Characterization of Extremal Antipodal Polygons

Let S be a set of 2n points on a circle such that for each point p ∈ S also its antipodal (mirrored with respect to the circle center) point p′ belongs to S. A polygon P of size n is called antipodal if it consists of precisely one point of each antipodal pair (p, p′) of S. We provide a complete characterization of antipodal polygons which maximize (minimize, respectively) the area among all an...

Extremal antipodal polygons and polytopes

5 Let S be a set of 2n points on a circle such that for each point p ∈ S also its antipodal 6 (mirrored with respect to the circle center) point p′ belongs to S. A polygon P of size n is called 7 antipodal if it consists of precisely one point of each antipodal pair (p, p′) of S. 8 We provide a complete characterization of antipodal polygons which maximize (minimize, 9 respectively) the area am...

Antipodal Gray codes

An n-bit Gray code is a circular listing of the 2 n-bit strings so that successive strings differ only in one bit position. An n-bit antipodal Gray code has the additional property that the complement of any string appears exactly n steps away in the list. The problem of determining for which values of n antipodal Gray codes can exist was posed by Hunter Snevily, who showed them to be possible ...
