Multiport array-antennas are widely used in beamforming, multiple input multiple output (MIMO), and diversity systems. In applications where a space less than half- wavelength is available, strong mutual coupling between antenna ports is introduced and causes system performance degradation. In addition, limited size of ground plane (chassis modes) will modify the radiation characteristics of the antenna array. Design of decoupling matching networks becomes of essential to compensate for the effect of mutual coupling. In this book, different approaches of decoupling networks will be presented. In the Eigenmode based decoupling approach, the mutual coupling is compensated through a physical path connected between array elements, while in the parasitic decoupling approach, antenna ports are decoupled through a coupling path between array elements. Both approaches are demonstrated for the monopole four square array antenna where four monopole elements are placed at the corners of an electrically small platform (chassis) to scan the beam in azimuth.

As wireless devices and systems get both smaller and more ubiquitous, the demand for effective but small antennas is rapidly increasing. Small Antenna Design describes the theory behind effective small antenna design and give design techniques and examples for small antennas for different operating frequencies. Design techniques are given for the entire radio spectrum, from a very hundred kilohertz to the gigahertz range. Unlike other antenna books which are heavily mathematical and theoretical, Douglas Miron keeps mathematics to the absolute minimum required to explain design techniques. Ground planes, essential for operation of many antenna designs, are extensively discussed. Author's extensive experience as a practicing antenna design engineer gives book a strong "hands-on" emphasis Covers antenna design techniques from very low frequency (below 300 kHz) to microwave (above 1 GHz) ranges Special attention is given to antenna design for mobile/portable applications such as cell phones, WiFi, etc

Download Antenna-on-Chip: Design, Challenges, and Opportunities Book in PDF, ePub and Kindle
Antennas are essential part of every wireless communication system. The increasing trend of applications in the radio frequency (RF) and millimeter wave frequency spectrum has reduced the antenna sizes to only a few millimeters, which makes it practical for on-chip implementations. Integrated Circuit (IC) designers who have traditionally remained isolated from antenna design now need to understand its design process and trade-offs. This comprehensive resource addresses the challenges, benefits and trade-offs of on-chip antenna implementation. It presents practical design and integration considerations of the IC and antenna combination and how both ends of the system can be utilized in a complimentary way. The book includes on-chip antenna layout considerations, layout for testability and various methods of their characterization. A look at the future trends and utilization of on-chip antennas for different applications concludes the book.
