The fifth generation of mobile technology is referred to as “5G.” 5G refers to the next
significant phase of mobile communications standards after the upcoming 4G standards …

Ever since the deployment of the first-generation of mobile telecommunications, wireless
communication technology has evolved at a dramatically fast pace over the past four …

In this paper, a novel technique of collocating a millimeter-wave end-fire 5G beam steerable
array antenna with a low-frequency planar inverted-F antenna (PIFA) is presented. In this …

This paper introduces a planar switchable 3-D-coverage phased array for 28-GHz mobile
terminal applications. In order to realize 3-D-coverage beam scan with a simple planar …

A dramatic evolution can be observed in cellular wireless communication. It started from
analog 2G (global system for mobile communication) toward high-data-rate systems such as …

In this paper, we outline the historical evolution of RF and microwave design optimization
and envisage imminent and future challenges that will be addressed by the next generation …

A compact beam-steerable antenna array is proposed for 28 GHz mobile terminals. The
proposed array consists of one active element and two passive parasitic elements. Two …

Uncertainty quantification is an important aspect of engineering design, also pertaining to
the development and performance evaluation of antenna systems. Manufacturing tolerances …

Electromagnetic (EM)-driven parameter adjustment has become imperative in the design of
modern antennas. It is necessary because the initial designs rendered through topology …

Millimeter-wave (mmWave) frequency bands are promising candidate spectrum for the fifth-
generation (5G) mobile communication system, but it requires high directional antenna …
