The frequencies of 400M/900M/1.2G/2.4G/5.0GHz are considered for wireless sensor used for the network of home electric appliances and energy management for environmental conservation. In this report, we suggest the antenna using electromagnetic coupling feed, it can operate of triple frequencies of 1.2G/2.4G/5.0GHz by one feeding. In order to design a loop antenna with small dimensions, we used capacity loaded loop antenna in 1.2G/2.4GHz. As a result, the maximum dimension of antenna becomes 31.5mm×31.5mm including a substrate, and the bandwidth characteristics less than return loss of -6dB are respectively 2.3%, 2.7%, 27.7% in 1.2/2.4/5.0GHz. For a maximum gains at each frequency band, when using the substrate of tanδ=0.02, the proposed antenna provides -2.69dBi, -3.34dBi, 3.19dBi. Furthermore, when using the substrate of tanδ=0.0025, maximum gains at each frequency are improved by 2.51dB, 3.01dB, 0.36dB. |
