Abstract
To fulfill user demands and solve the difficulties introduced by the fifth generation
(5G) system, a significant modification in the strategy for 5G wireless cellular
architecture is required. To address this issue, a new concept or design method for
planning 5G cellular architecture has emerged: distinguishing inside and outside
configurations.
Massive Multiple-input Multiple-output (M-MIMO) technology will help to
support this approach. Long-Term Evolution (LTE) antennas with conventional 2×2
MIMO antennas can no longer provide such high data throughput and spectral
efficiency. MIMO technology must be used in 5G wireless communication systems to
satisfy the requirements of 5G mobile communication, since a large MIMO system
may offer a high channel capacity. For communication with indoor users, several
wireless access points that have a large number of antenna arrays are required. This
will increase the cellular system’s energy efficiency, average throughput, data rate, and
spectrum efficiency greatly.
This thesis focuses on the developing of 5G massive MIMO applications in mobile
handsets and indoor base- station antenna arrays and reports some of their challenges.
Based on the previous discussion, this thesis proposes three significant
contributions to solve the difficulties and challenges identified. They may be
summarized such as this:
A proposed design of a dual-band 10 × 10 antenna array for 5G Massive MIMO
applications in the mobile phone is presented. The designed array proposes ten
ring loop antenna elements integrated into a limited space cell phone circuit
board to cover the sub-6 GHz LTE band 42 (3.4 – 3.6 GHz), LTE band 43 (3.6
– 3.8 GHz), and LTE band 46 (5.15 – 5.925 GHz).
A fourteen port MIMO array is proposed for 5G cellphone applications. A
dual-band ring loop antenna is proposed to cover the LTE bands (LTE band
42/43 and LTE band 46).
A proposed wideband 16- element indoor base station (BS) antenna array that
can cover 3.3–6.0 GHz is proposed for 5G applications. A π-shaped monopole
antenna is designed to cover the sub-6 GHz bands: Lower band (LTE bands
42/43 - N77 - N78), intermediate band (N79), and higher band (LTE 46).
