چکیده
in this work, a design of quadrifilar helical antenna with characteristics of compact, wideband and circular polarization is presented. It is achieved by combining the ways of tuning the different dimensions of the pairs of bifilars, and a feeding structure for providing the self-phasing technique. Both of simulated and measured results are reported in this study.

متن کاملDesign 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 ...
