Switched parasitic planar arrays, as possible implementations of smart antennas, and an
efficient method of designing them are presented in this paper. The radiation pattern of an array …

The,design of modified Yagi-Uda arrays with additional parasitic elements in the area of the
radiating dipole, acting either as reflectors or directors, is presented. The genetic algorithms …

An electronically controllable, switched parasitic planar array can be used for the purpose of
direction finding. The method proposed in this paper exploits the electronic beam steering, …

Circular switched parasitic dipole arrays are designed in this letter, using the method of genetic
algorithms. Three possible configurations are proposed: a simple circular array with one …

Measurements and simulation are used to study fast‐fading variations of the received
continuous‐wave signal envelope in non‐line‐of‐sight (NLOS) indoor environments at 1800 MHz. …

In this paper, a model for performing bit-error-rate (BER) analysis of various channel models
is presented. Traditional simulation methods model the mobile radio channel as having …

Radio channel observation and characterization is indispensable in mobile communications
systems development. Efficient propagation prediction is crucial for rapid and cost-effective …

The technology of adaptive antennas is rapidly growing during the last years. It is true that
switched beam antennas, the simplest type of smart antennas, may provide substantial …

In the present paper, a combined method of auxiliary sources (MAS)-reaction matching (RM)
approach is presented for the analysis of arrays of arbitrarily located cylindrical dipoles. It is …

Switched parasitic planar arrays can be used for the purpose of electronic beam steering. The
insertion of a digital word in the antenna's feeding circuit may give a radiation pattern with …
