The design parameters of an omnidirectional planar microstrip antenna are examined. The impedance bandwidth and radiation efficiency increase as the element width is increased. Increasing the element width can cause a lower‐order mode to increase in frequency and degrade the omnidirectional pattern and sidelobes, and thus creates a beam scan from broadside. This beam scan and pattern degradation can be eliminated with narrower elements or by moving the position of the shorting pins at the expense of impedance bandwidth. © 2005 Wiley Periodicals, Inc.
