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.
