The omni microstrip antenna: a new small antenna

The omni microstrip antenna is a microstrip-shorted quarter-wave resonator that is wrapped around a cylinder. It is an electrically short antenna, and it can be made to radiate an omnidirectional pattern normal to the axis of the cylinder. Equations governing the design of the antenna are given along with a method of excitation. An example of a design at 41.4 MHz is given, and experimental results are reported.
