Autor: M. Mrnka, P. Vasina, M. Kufa, V. Hebelka, Z. Raida

Publikováno v: International Journal of Antennas and Propagation, Vol 2016 (2016)

This paper deals with suitable antennas for energy harvesting, which is a growing research field due to the utilization of nowadays ubiquitous and abundant RF energy. Four types of basic antenna structures suitable for harvesting applications, namely

Comparison of Planar Fractal Filters on Defected Ground Substrate

Autor: M. Kufa, Z. Raida

Publikováno v: Radioengineering, Vol 21, Iss 4, Pp 1019-1024 (2012)

The paper discusses approaches to the reduction of dimensions of planar filters (microstrip ones and coplanar ones). Filter dimensions are reduced by applying the fractal theory to the geometry of a filter, and by the defecting of the ground plane of

The paper is focused on a formulation of a new coefficient of the low-pass prototype filter for the design of a four-element filtering antenna array. Due to the new gicoefficients, we can comfortably and easily control a shape of the frequency respon

Lowpass filter with reduced fractal defected ground structure

Autor: Zbynek Raida, M. Kufa

Publikováno v: Electronics Letters. 49:199-201

Presented is the design of a planar lowpass filter with stubs separated by transmission lines. To minimise dimensions, the filter is completed by a fractal defected-ground structure (DGS). The fractal DGS filter requires a 20% smaller substrate compa
