Compact massive MIMO antenna array for small 5G base stations

Massive MIMO for 5G

Massive MIMO is the currently most compelling sub-6 GHz physical-layer technology for future wireless access. The main concept is to use large antenna arrays at base stations to simultaneously serve many autonomous terminals, as illustrated in Figure 1. The rich and unique propagation signatures of the terminals are exploited with smart processing at the array to achieve superior capacity. Mass...

Higher-order Mode Rectangular Dielectric Resonator Antenna for 5G Applications

The excitation of the higher-order mode, in rectangular dielectric resonator designed was explored to enhance the antenna gain and detailed elaboration is presented in this paper. The antenna was fed by a 50Ω microstrip line through an aperture cut in the ground plane. Besides avoiding spurious radiation, this feeding technique gives flexibility in controlling the amount of coupling in order to...

A Compact 4G MIMO Antenna Integrated with a 5G Array for Current and Future Mobile Handsets

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 millimeter(mm)-wave antenna array. The MIMO antenna system consists of two rea...

Design and Analysis of Switch Mode Amplifier for Actuator Array Using MIMO Optimal Feedback Quantization

The system analysis of the MIMO optimal feedback quantization used to produce switching signals is proposed here. The switching signals are then fed into the switch mode power amplifier to drive actuator array. The architecture of the power amplifier used in this paper allows the sharing of switching elements among actuators and is different from the traditional one-to-one method in actuating a...
