This paper addresses the miniaturization of Archimedean spiral antennas by using stacked resonant metallic rings. Such rings are electromagnetically coupled to spiral antennas and play a key role in the reduction of the antennas diameter. A methodology for selecting very compact resonant rings based on fractal geometry is reported. The fabrication of spiral(More)
This paper presents parts of investigations done in a VHF spherical Near-Field system in order to propose appropriate measurement procedure. First is briefly presented the mono-probe near field system and measurement challenges due to low frequencies. Then is presented the Antenna Under Test (AUT), the antenna pattern comparison approach and the measurement(More)
this paper presents a new electromagnetic approach of matrix antenna, specialized for circularly polarized space applications. The design of the proposed antenna matrix is based on small pixels which generate circular polarization field. The concept of the pixels is well demonstrated as a patent and verified for the use in antenna arrays. The design will be(More)
