Chapter 4 UWB antenna arrays

Grzegorz Adamiuk

A well-known method of increasing the gain and lower the half-power beamwidth of the radiation pattern is to replace the single radiator by an antenna array. Its application in communications is interesting if, for example, a point-to-point connection is to be established. It is of special interest in MIMO systems, where a channel capacity might be increased if multiple radiators, either on the transmit or the receive side (or both) are used [75]. In radar systems an application of arrays is more common in order to achieve lower half-power beamwidths, which in general are used to increase the angular resolution.

In this chapter, specific design issues of UWB antenna arrays are described. According ...
