Because the existing approaches for diagnosing sensor networks lead to low precision and high complexity, a new fault detection mechanism based on support vector regression and neighbor coordination is proposed in this work. According to the redundant information about meteorological elements collected by a multisensor, a fault prediction model is built using a support vector regression algorithm, and it achieves residual sequences. Then, the node status is identified by mutual testing among reliable neighbor nodes. Simulations show that when the sensor fault probability in wireless sensor networks is 40%, the detection accuracy of the proposed algorithm is over 87%, and the false alarm ratio is below 7%. The detection accuracy is increased by up to 13%, in contrast to other algorithms. This algorithm not only reduces the communication to sensor nodes but also has a high detection accuracy and a low false alarm ratio. The proposed algorithm is suitable for fault detection in meteorological sensor networks with low node densities and high failure ratios.

A compact wideband circularly polarized (CP) horn antenna with slot‐coupled feeding structure at Ku band for satellite communication is devised. The proposed design is based on a square aperture horn antenna with two orthogonal ridges, which is fed by nonuniform curved slot along the diagonal of the horn on the bottom cavity. And in order to improve the impedance matching, a staircase typed ridge is connected the feeding probe as a matching network. Moreover, two orthogonal ridges are excited with a tapered slot coupled by the staircase ridges via feeding probe. Wideband CP performance is achieved with an overall physical dimension of 9 mm × 9 mm × 14 mm (0.045λ0 × 0.045λ0 × 0.07λ0 at frequency of 15 GHz). It is experimentally demonstrated that the proposed antenna achieves: a wide 10‐dB return loss bandwidth of about 2.4 GHz, a 3‐dB axial ratio bandwidth of 1 GHz, and a peak gain of 6.5 dBi.

“…Moreover, in dynamic scenarios, the body kinetic shadowing effects will keep causing temporal variation of the link polarization . Such impacts to the antenna's efficiency, frequency response, and radiation pattern are widely observed when close to bio‐tissues and human bodies . To maintain the antenna's performance and for advanced communication techniques, for example, distributed multirelaying, a multipolarization antenna design can alleviate the body effects and become more adaptive to improve the link quality.…”

On‐body communications show highly polarization selectivity in both radio channels and antennas due to the complex body coupling and scattering effects, and full‐space dimension link distribution. To mitigate the polarization variation of on‐body communication links, multipolarization antennas are proposed to adaptively capture the on‐body channel polarization components. In this article, a tri‐polarization antenna design is introduced with its performance evaluated on a simplified three‐layered human chest model including skin, fat, and muscle tissues. The return loss, frequency response, and the radiation pattern of designed antenna are found to be affected by the relative orientation and distance between the antennas and the trunk, indicating the necessity of the antenna emplacement optimization for realistic on‐body communication devices.
