Network sensor miniature antenna

Nowadays, Sensor network is extensively practical in numerous fields including general engineering, agriculture and environmental monitoring, health monitoring and surgery [1]. Sensors are designed as increasingly efficient and Miniature. As a matter of fact, the most important factor in the design of RF communications is the size of the antenna [2]. In fact, Miniaturization will be subject to steady progress, except for two crucial components which are the antenna and the battery. Here, it is a real challenge to discover original solutions to go a step forward. This paper introduces the concept of a meandered rectangular patch antenna using gap matching impedance with planar feed. A reduction of about 60% compared with the conventional microstrip patch antenna has been eventually achieved.
