The first time that such a complete systematic analysis of the mathematical and numerical
techniques related to the orthogonal methods has been given. With the explosion of the …

In this paper, a multiband noncontact temperature-measuring microwave radiometer system
is developed. The system can passively receive the microwave signal of the core …

The aperture phase taper due to quadratic phase errors in the principal planes of a
rectangular horn imposes signifi-cant constraints on the on-axis far-field gain of the horn …

This letter describes a method for calculating the half-power beamwidths of a pyramidal horn
in closed form as a function of its gain and aperture phase error. The derived expressions …

This paper proposes a novel design criterion for optimal pyramidal horns. According to it, the
optimal aperture phase error parameters of a pyramidal horn are determined from the …

This chapter describes the design and modeling of horn-based phased-array antennas
using analytical approaches. Phased-array antennas are important devices for 5G wireless …

Özet Parçacık sürü optimizasyonu yakın tarihte ortaya konulmuş bir evrimsel hesaplama

In wireless communications, knowledge of the node-to-node distance is essential in tasks
such as system configuration, protocol design, and performance analysis. In this paper, we …

In this work, we apply classical and new self‐adaptive differential evolution (DE) algorithms
to the design of optimum gain pyramidal horns. The application of DE algorithms to …

This paper proposes a novel design method for pyramid horns which are under the
constraints of 3 dB beamwidth. It is based on the general radiation patterns of E/H planes …
