Criteria for Nearly Omnidirectional Radiation Patterns for Printed Antennas,
Abstract
Radiation from printed antennas is investigated with emphasis placed on producing E- and H-plane radiation patterns which are as nearly omnidirectional as possible. This is achieved using criteria which are derived for a nonzero radiation field extending down to the layer surface (radiation into the horizon). It is determined that this phenomenon arises when a surface wave pole coincides with a branch point in the complex plane. A simple ray optics interpretation is given for a phenomenon, and graphs are presented to easily enable design of printed antenna geometry to achieve nearly omnidirectional E- or H-plane patterns.
