Abstract

The paper presents the results of modeling and measuring the characteristics of a prototype flat spiral antenna designed for reception of signals in the GPS station. The proposed design consists of a combination of Archimedean and logarithmic spirals, and provides working frequencies of 1.2 GHz and 1.6 GHz, and the reception of signals with any kind of linear polarization. The basic characteristics of the antenna, modeled in the microwave CAD package HFSS v.10, and the characteristics obtained in the measurement of the antenna prototype. Modeling results were confirmed by the measurements of the experimental model of the antenna.
