Practical Antenna Design for handheld devices is demonstrated through the utilization of the modal/Eigenmode theory of antennas. Here, a review of the underlying design fundamentals is outlined. Next, a design example featuring the antenna design of a modern smartphone is presented. The design cycle is simplified through finding an antenna with appropriate complex resonance frequency to cover a required...
The paper discusses the application of the Characteristic Mode Analysis (CMA) to a number of problems arising in practical antenna applications, and identifies some challenging issues that have been encountered by in the process of applying the CMA to some real-world problems. These include, among others, excitation of the Characteristic modes on complex platforms; antenna placement on these platforms...
