چکیده
A novel monopole asymmetric fractal micro strip antenna is designed and analyzed in this paper. The proposed Koch fractal monopole antenna is resonating at triband with circular polarization operation. Five diff structures without slot (basic model), single slot (Iteration 1), double slotted (Iteration 2), triple slotted (Iteration 3), and optimized fractal slot (Iteration 4) are studied for circular polarization radiation. Perturbations in the structure for triband CP radiation are introduced by employing optimization in the asymmetrical Koch fractal curves as boundaries of a square patch and embedded triangular slots. The generated 3-dB axial ratios are analyzed with the simulation results demonstrate that the proposed antenna design is suitable for wireless communication applications.

A new shaped circularly polarized dielectric resonator antenna (CP DRA) is studied with branch-line coupler and log-periodic balun for the GPS application. Since the coupler and balun are located under the DRA, it does not increase the footprint of the antenna, as a result the system is very compact. Two configurations are considered in this paper. In the first configuration, an external 50Ω lo...
