This book highlights technology trends and challenges that trace
the evolution of antenna design, starting from 3rd generation
phones and moving towards the latest release of LTE-A. The authors
explore how the simple monopole and whip antenna from the GSM years
have evolved towards what we have today, an antenna design that is
compact, multi-band in nature and caters to multiple elements on
the same patch to provide high throughput connectivity. The scope
of the book targets a broad range of subjects, including the
microstrip antenna, PIFA antenna, and the monopole antenna to be
used for different applications over three different mobile
generations. Beyond that, the authors take a step into the future
and look at antenna requirements for 5G communications, which
already has the 5G drive in place with prominent scenarios and
use-cases emerging. They examine these, and put in place the
challenges that lie ahead for antenna design, particularly in
mm-Wave design. The book provides a reference for practicing
engineers and under/post graduate students working in this field.

An approach to hybridisation of the Method of Moments (MoM) and the
Finite Difference Time Domain (FDTD) method is investigated. This
hybrid method is capable of analysing a system of multiple discrete
regions by employing the principle of equivalent sources to excite
their coupling surfaces. Examples are provided to indicate both the
potential and limitations of the hybrid method. It is shown that
this technique has the great advantage of accurately modelling
complex and arbitrarily oriented mobile telephone handset antennas,
especially typical helical types, in the proximity of a detailed
voxel representation of the human head, as required for safety and
radiation pattern assessments. A new technique to reduce power
dissipation in tissues close to mobile telephones is investigated,
resulting in a novel design of bifilar helical antenna. Different
personal communication terminals used for satellite communications
and radio base stations, considered in the proximity of
inhomogeneous dielectric bodies are studied, illustrating strengths
of using the hybrid method in such applications.
