Abstract:

Received wireless power can be increased under the same conditions by reasonable installation angle of directional antennas.A 230 MHz normal mode helix antenna of micropower wireless communication module in a smart meter is designed and implemented.Directivity of the antenna is discussed.The installation angle of antenna is improved based on actual installation mode of antenna and the smart meter.Simulation and measurements show that the average received wireless power in a micropower wireless communication module increases by 2.4 dBm as compared to that without installation angle improvement.In the same environment and the same signal encoding modulation mode, signal-to-noise ratio of the received signal is increased, and therefore quality of wireless communication between a smart meter and a concentrator can be improved.

Key words: smart meter, helical antenna, radiation pattern, power wireless communication
