Definitions of Critical Parameters for Antenna operation, frequency response) and the radiation characteristic (or radiation pattern). Usually, frequency response is considered first because without a reasonable input impedance match, a transmitting system may suffer from severe reflections that could damage other components and waste power, whereas recei

The way antennas function as parts of circuits has direct consequences for how they behave as radiators, and vice versa. This, of course, leads to the conclusion that the reconfiguration of one property, say, frequency response, will have a

Methods for Achieving Radiation Pattern Reconfigurability, radiation is typically characterized with a set of two-dimensional radiation patterns taken from major cut planes of interest, with three-dimensional patterns used occasionally to obtain a qualitative assessment of the antenna’s performance. In this lecture, we will typically examine cut planes of

Indeed, this ability to independently select operating frequency, bandwidth, and radiation pattern characteristics is the ultimate goal of reconfigurable antenna designers. Recently, several groups have achieved this kind of reconfigurability, here termed

Conclusions and Directions for Future work, However, there are still very few reconfigurable antennas in use today. Why? There are several answers to this question, and they each point to a promising area of future research and development in this field.

Introduction, category possesses inherent benefits and detriments that make them more or less suitable for particular applications. When faced with a new system design, engineers change and adapt these basic antennas, using theoretical knowledge and general design guidelines as starting points to develop new structures that often produce acceptable results.

Antennas are necessary and critical components of communication and radar systems, but sometimes their inability to adjust to new operating scenarios can limit system performance. Making antennas rec
