Radiation efficiencies of a compact planar antenna with different meander line configurations

This paper investigates the radiation efficiencies of compact meander line antennas designed for wireless networking of energy meters. The wireless band dedicated for this application in India is 865–867 MHz. Due to space limitations within existing energy meters, the design of the antenna is constrained within 12×18 mm2. Investigations were performed using electromagnetic simulation software Zealand IE3D, a MOM based software simulation tool.
