  • WCNC - Some thoughts on the design of printed log-periodic antennas for long Range Communication modules
    2019 IEEE Wireless Communications and Networking Conference (WCNC), 2019
    Co-Authors: Gian Luigi Gragnani, Claudio Montecucco
    Abstract:

    In this paper the general procedure for designing the traditional log-periodic dipole antennas made of metallic rods in free space is analyzed and used as the starting point to discuss the design for printed antennas. In particular, focus is on the design of log-dipole printed antennas to be used in long Range Communication modules for wireless sensor networks. Starting from a preliminary set of simulations, some criteria are derived, that can help to quickly synthesize a new printed antenna. An example of a designed antenna is also presented, showing the effectiveness and the reliability of the new method.

  • IWCMC - Design of printed log-periodic antennas for long Range Communication modules: preliminary simulation results
    2019 15th International Wireless Communications & Mobile Computing Conference (IWCMC), 2019
    Co-Authors: Gian Luigi Gragnani, Claudio Montecucco
    Abstract:

    Starting by the general procedure for designing the traditional log-periodic dipole antennas made of metallic rods in free space a new procedure to design printed log-periodic antennas is derived and discussed. In the paper, particular focus is given to the design of log-dipole printed antennas to be used in long Range Communication modules for wireless sensor networks, but the procedure can be easily extended to other frequency bands. Starting from a preliminary set of simulations, some criteria are derived, that can help to quickly synthesize a new printed antenna. An example of a designed antenna is presented. Results, although preliminary, show the effectiveness and the reliability of the new method.

  • A Log-Periodic Antenna for Long Range Communication Within a Wireless Sensor Network System for Sea Water Quality Monitoring
    2018 Advances in Wireless and Optical Communications (RTUWO), 2018
    Co-Authors: Gian Luigi Gragnani, Daniele D. Caviglia, Claudio Montecucco
    Abstract:

    In this paper the design of a printed log-periodic antenna for long Range Communication within a wireless sensor network system for sea water quality monitoring is presented. The difficulties in using the design procedure for log-periodic dipole antennas proposed by Carrel are discussed and some limitations are pointed out. New design hints are given and a preliminary example of a printed antenna is presented. Simulations are carried out not only for free-space but also in presence of sea and wave motion. Resuts show that printed log-periodic is actually a good candidate for the intended application.

  • ANT/SEIT - Enhanced RLS in Smart Antennas for Long Range Communication Networks.
    Procedia Computer Science, 2018
    Co-Authors: Peter Nnabugwu Chuku, Thomas O. Olwal, Karim Djouani
    Abstract:

    Abstract The utilisation of smart antenna (SA) techniques in future wireless and cellular networks is expected to have an impact on the efficient use of the spectrum and the optimization of service quality. This is because SAs can enhance the maximization of output power of the signal in desired directions amongst a whole lot of functions. Despite these benefits of SAs, long Range Communications still face unsolved challenges such as signal fading. Therefore, this paper focuses on enhancing the recursive least squares (RLS) in SA design for long Range Communication networks. The conventional RLS algorithm does not need any matrix inversion computations because the inverse correlation matrix is determined directly. Therefore, the RLS saves computational power. Hence, we have enhanced the RLS algorithm by introducing a constant m to the gain factor in order to yield an improved gain vector. Results from our simulations show that the enhanced RLS reduces mean square error (MSE), smoothens filter output and improves signal-to-noise ratio (SNR). These benefits further result in the antenna’s gain improvement leading to an increased Range and directivity of the smart antenna over a long Range Communication networks.
