This paper proposes the design and simulation of 2×2 circular patch antenna array working at 28 GHz by using four inset feed micro strip circular patch antennas to achieve beam forming with directivity around 13dB which is required to overcome part of high path loss challenge for high data rate mm-5G mobile station application. Four element 2x2 array consists of two 1x2 circular patch antenna arrays based on power divider and quarter wavelength transition lines as a matching circuit. The designed antenna array is simulated on RT/duroid 5880 dielectric substrate with properties of 0.5mm thickness, dielectric constant ε r =2.2, and tangent loss of 0.0009 by using Computer System Technology (CST) software. The performances in terms of return loss, 3D–radiation pattern is evaluated at 28 GHz frequency band. The design also includes the possibility of inserting four identical 2x2 antenna arrays at four edges of mobile station substrate to achieve broad space coverage by steering the beams of the mobile station arrays.

Analysis of the CaTV splitters

Krzemieniecki D., Juchniewicz J.

Electronics and Telecommunications Quarterly

2008

Vol. 54, No 2

203-221

This article presents CaTV splitters. Basic features of splitters and influence of basic factors on crucial parameters were investigated in this article. Additionally, correction circuits for parameters improvement were proposed. The research considered two-way, three-way and four-way splitters. Some examples of applications of splitters in passive devices used in CaTV network were presented.
