Radiation properties of an omnidirectional planar microstrip antenna

The pattern and directivity of an ideal omnidirectional antenna, collinear coaxial, and omnidirectiontal microstrip antenna (OMA) are compared. The radiation of an OMA originates from the arraying of two radiating edges along each element. The width of the (OMA) elements determines omni‐plane pattern variation. © 2007 Wiley Periodicals, Inc.
