Description
A planar dual-band circular antenna for a chemical wireless sensor network is presented in this paper. Four antennas compose the wireless sensor package and one antenna is selected at a given time using an SP4T switch. This work describes the unit antenna used to transmit sensor information to a nearby hub that operates in the ISM bands. The antenna is composed of concentric shorted annular rings using substrate integrated waveguides and includes a circular patch at its center. The antenna presents two types of radiation patterns, one omnidirectional in the azimuth plane at 2.4 GHz, and one unidirectional in the elevation plane at 5.8 GHz. The simulated gains obtained at 2.4 GHz and 5.8 GHz are 2.98 dB and 7 dB, respectively
