In this paper two proposed methods of input impedance calculation for Bow-Tie antenna are introduced. The proposed methods show input impedance calculation with high accuracy. Also, design curves for input impedance values were developed depending on

The paper discusses the influence of higher harmonic components in the measured signal on the measurement uncertainty of RF level when diode power sensors are used. A method is proposed to evaluate the measurement uncertainty of different diode power

The mutual electromagnetic interference among macro users and femto users is a challenge, when femtocells are deployed in LTE and LTE advanced systems. When the used femtocells have a closed access, the macro users, who are indoors or near to the fem

The deployment of femtocells in a LTE advanced system can extend the system coverage to include indoors. Unfortunately, an electromagnetic interference may occur among the femto users and the macro users in the case of co-channel deployment. A cognit

Cognitive radio is an emerging technology, which aims to upgrade the spectrum utilization by allowing the secondary users to operate at the spectrum bands vacated by the primary users. A cognitive radio system model was simulated and the performance

An electromagnetic band gap (EBG) waveguide using holes drilled in a dielectric substrate is investigated in this paper. A broadbanding technique is suggested and implemented through a detailed study of the modal behaviour of the guiding structure. T

A broadside radiation from an electromagnetic band-gap (EBG) waveguide is achieved. The EBG waveguide, which operates around 30 GHz, is designed using a square lattice of metal vias to build a spatial power combiner. A surface mode was excited by add

The transition between two different electromagnetic band-gap (EBG) structures is investigated in this letter. A triangular lattice of holes with a partial band-gap was used to design an EBG waveguide for TM modes (magnetic field parallel to the subs

A triangular lattice of holes is used to design an electromagnetic band-gap (EBG) waveguide for TM modes (magnetic field parallel to the substrate surface and perpendicular to the holes) for operation in the millimeter-wave range. This EBG waveguide
