A novel integrated antenna solution for wireless handheld devices is proposed for the existing 4G standards and upcoming 5G systems for broadband, high data rate communications. The complete antenna system is a unique combination of a multiple-input–multiple-output (MIMO) antenna system at microwave frequencies and a millimetre (mm)-wave antenna array. The MIMO antenna system consists of two reactive...
In this paper, an integrated antenna system is proposed for existing 4G as well as upcoming 5G broad-band communication systems. The integrated solution is a combination of a microwave multiple-input-multiple-output (MIMO) antenna system along with a millimeter(mm)-wave antenna array. The MIMO antennas are operating over a wide-band covering several well-known wireless standards between 1870 ∼ 2530...
A millimeter wave (mm-wave) beam-forming network based on the Butler matrix is designed alongside with its planar antenna array. The designed system has 1 GHz of BW centered at 28.5 GHz. A planar 4×4 slot based antenna array is connected to the Butler matrix via optimized series feeds. The beams radiated from the antenna array were steered to four different locations; ±20° and ±45°. The maximum gain...
A millimeter wave (mm-wave) two-dimensional slot antenna array, operating at 28 GHz, is designed and presented in this paper. The antenna array consists of 8 elements in a 2×4 configuration. A 1-to-4 power divider is feeding the 2×4 slot antenna array in both schemes; parallel and series. The bandwidth achieved for the integrated system was almost 5% with a center frequency at 28.2 GHz. The occupied...
