Foreword to Antennas For Portable Devices PDF

The tremendous success enjoyed by the cellular phone industry and advances in radio frequency integrated circuits have in recent years fostered the development of various wireless technologies.

Including RFID, mobile internet, body-centric communications, and UWB, which are operated at microwave frequencies. (Antennas For Portable Devices by Zhi Ning Chen)

For aesthetic reasons, all these systems require small antennas that can be embedded in the mobile units. Furthermore

For minimally invasive microwave thermal therapies, small and thin antennas are much preferred. Ten years ago. (Antennas For Portable Devices by Zhi Ning Chen)

Dr. Zhi Ning Chen the editor of this Antennas For Portable Devices by Zhi Ning Chen PDF Book was a research fellow at the City University of Hong Kong, working on the design of dielectric resonator antennas.

Back then, we were already impressed by the creativity he showed in antenna research and by his leadership skills. (Antennas For Portable Devices by Zhi Ning Chen)

His achievements in designing many innovative antennas for wireless applications have been outstanding. This edited Antennas For Portable Devices by Zhi Ning Chen PDF Book represents another significant achievement.

Bringing together contributions from key players in the topical areas of antenna designs for RFID tags, laptop computers, wearable devices, UWB systems, and microwave thermal therapies.

Major issues and design considerations are discussed and explained in the various chapters. (Antennas For Portable Devices by Zhi Ning Chen)

I am sure that this Antennas For Portable Devices by Zhi Ning Chen PDF Book will be proven to be of considerable value to practicing engineers, graduate students, and professors engaging in modern antenna research.

I am delighted to extend my hearty congratulations to Dr. Chen and all the authors of the chapters of the Antennas For Portable Devices by Zhi Ning Chen PDF Book.

Introduction to Antennas For Portable Devices PDF


Antennas for portable devices may be small in terms of [2]:

  1. electrical size. The antenna can be physically bounded by a sphere having a radius equal to freespace/2. Planar inverted-F antennas with shorting pins or/and slots are typical examples of this category.

  2. physical size. An antenna which is not electrically small may feature a substantial size reduction in one dimension or plane. Microstrip patch antennas with ultra-low profiles belong to this category.

  3. function. An antenna which is not electrically or physically small in size may possess additional functions without any increase in size. Dielectric resonator antennas operating in multiple modes fit this definition.

Therefore, the miniaturization of antennas for portable devices can be carried out in various ways because basically, the research and development of antenna technology are application-oriented. (Antennas For Portable Devices by Zhi Ning Chen)

With the rapid increase in the number of mobile portable devices, many technologies have been developed to miniaturize the antennas.

The technologies can be broadly classified as follows:

  1. The design and optimization of antenna geometric/mechanical structures, in particular, the shape and orientation of the radiators, loading, as well as the feeding network. This is a conventional approach and most often employed in antenna design. Inverted-F antennas, top-loaded dipole antennas, and slotted planar antennas all fall into this category.

  2. The use of non-conducting material. Antennas loaded with ferrite or high-permittivity dielectric materials (for instance, ceramics) are examples of this type of technology, as is the dielectric resonant antenna.

  3. The application of special fabrication processes. The fabrication of printed circuit boards and low-temperature co-fired ceramics have made co-planar and multiple-layer microstrip patch antennas popular. Such technologies are conducive to the mass production of miniaturized antennas at low cost.

This Antennas For Portable Devices by Zhi Ning Chen PDF Book aims to introduce advanced progress in miniaturizing antennas for portable mobile devices. The portable mobile devices will include mobile phone handsets; RFID tags. 

Laptops with embedded wireless local area network (WLAN) access points; medical devices for microwave thermal therapy. (Antennas For Portable Devices by Zhi Ning Chen)

Sensors installed on or above the human body, and ultra-wideband (UWB) based high-data-rate wireless connectors such as the wireless USB dongle. All of these portable mobile devices are widely used.

The antennas used in them have become a bottleneck in the miniaturization of portable devices in terms of performance, size, and cost.
