    (Department of Electrical Engineering, Ahmadu Bello University, Zaria, Nigeria., 2020-09-25) Zakariyya, Sikiru Olayinka; Abara, I E; Olayanju, Sunday Akinwale; Salami, A F; Sadiq, B O; Alao, R A
    This paper presents the design and implementation of a low-cost, low-complexity, energy-efficient controller with remote recharge and load shedding capability. The system is recharged remotely by an SMS sent to a registered SIM card in a GSM module, a voltage and current sensor measures the load power usage, a microcontroller is used to keep track of the power consumption and signals the relay in order to execute the load shedding when the predetermined threshold is reached. The whole system is powered by a power supply unit which converts the 220V AC from the supply mains to a 5V DC. After the design and upon testing, the energy measurement circuit worked with minimal error, the relay switch executed the load shedding function without delay, the GSM showed good network reception and the operation of the system was cheap and simple thus satisfying the objective of the research

    An Improved U-Slot Based 1 X 2 Triple Band Antenna Array for Flying Ad-hoc Networks (FANETs)
    (Abubakar Tafawa Balewa University, Bauchi Nigeria, 2017-12) Sadiq, B O; Zakariyya, O S; Olayanju, Sunday Akinwale; Adedokun, A E
    The objective of this paper is to design an improved U-Slot based 1 X 2 triple band antenna array for Flying Ad-hoc Networks (FANETs). The purpose of this modification is to increase the bandwidth and gain of the existing 1 X 2 triple band antenna array. This is because high bandwidth and gain are essential requirement for UAVs in FANET. However, to achieve this, the resonating frequency needed to be selected appropriately. The proposed antenna array resonates at 3.2GHz, 5.1GHz and 6.4GHz frequency band respectively. The antenna is optimized using a U-Slot resonating at triple-bands by introducing two symmetrical slits at the non-radiating edges of the patch. Simulation results were achieved using CST Studio and showed that the antenna has a bandwidth of 313MHz, 51MHz and 167MHz for the three bands respectively. This implies that practical applications can be achieved using this antenna.
