“…For dual K‐band, band operation horn antennas and array antennas using helical exciters are suffered with integrated difficulties and high‐manufacture cost. To overcome these drawbacks, some planar multiband antennas were reported, such as the patch antennas and slot antennas . Several studies on multifrequency slot antenna have been reported in recent years .…”

In this article, a novel substrate integrated waveguide (SIW) is used to design multifrequency cavity‐backed log‐periodic slot antenna. The proposed design has three layers of cavity‐backed structure namely feeding SIW, resonant SIW, and log‐periodic slot SIW in order to achieve low loss, high gain, and easy integration with high‐frequency components. The proposed structure also includes an inductive window slot to couple the energy from feeding SIW to resonant cavity. The experimental results shows that 10‐dB impedance bandwidth of 870 MHz (7.9%), 390 MHz (2.7%), 410 MHz (2.5%), 310 MHz (3.9%), and 420 MHz (2.2%) are obtained at resonant frequencies 11.25 GHz, 14.25 GHz, 15.95 GHz, 16.9 GHz, and 19.15 GHz, respectively. Also, a realized gain of around 18.24 dB is obtained at the bore sight direction. Moreover, the simulated and experimented results are in good agreement and make the antenna more suitable for Ku and K band applications.

Abstract. In this paper, a design for wideband and low cross polarization slot antenna at X band is presented. By adopting the double-layer slots and strip-line structure, the proposed antenna obtains a good characteristic of wide band. And unidirectional radiation is achieved by adding a planar reflector. In order to solve the weakness of high cross polarization and pattern distortion for wide slot antenna, an antiphase balanced feed network is introduced. Simulation results proved that the proposed antenna lowers the cross polarization level (XPL) while maintaining a bandwidth of 46.3% from 7.5GHz to 12.5GHz. The largest XPL in the range of half-power angle is -20dB. And the gain is 8.4dBi to 9.5dBi within the operating band.

Body Sensor Networks (BSN) is a developing area of research that allows wireless sensors to collect important parameters and monitor the human body. The wrist movement of a test subject running at moderate speed was monitored using accelerometer sensors. The sensor nodes were programmed to follow a gesture transmission technique to collect acceleration data and to predict the best limb position for communications while the athlete is moving. This paper reports a high reliability wireless network to acquire 50Hz movement acceleration during running. This reduces transmission power and increases the reliability. A result of 30% data loss was reduced to around 1% compared to continuous communications. This technology is important for a wide range of monitoring applications including measuring movement symmetry, physiology and athlete rehabilitation.
