Abstract

In this paper a small antenna is proposed for wireless sensor network applications in the frequency band of 5 GHz to 15 GHz. Wireless Sensor Networks (WSN) is having significant attention due to their numerous features nowadays. The most important component in sensor is its TX/RX antenna. In this design a new efficient CRLH based DNG metamaterial antenna is proposed. The design of the unit cell of these antennas is based on the composite right/left-handed (CRLH) transmission line model. Antenna1 used two patches and obtained results are compared with antenna2 with four patch. In this paper, we introduce a new method of design of CRLH metamaterial antennas to tackle the above problem using CRLH mushroom structure. The results of antenna2 show improvements over antenna1 in gain and bandwidth. By employing CRLH geometry, an overall size reduction of 65% was achieved compared to the conventional rectangular patch antenna. The proposed antenna can be easily built in a miniaturized wireless sensor network (WSN). RogersRT/Duroid 5880 is taken as substrate with thickness 1.572 mm and relative permittivity 2.2. The bandwidth of this antenna less than 10 dB is 700 MHz and the percentage of the bandwidth is 6.1%. The antenna characteristics, such as return loss and VSWR achieved by the proposed structure are plotted.
