Wind energy has been identified as a critical component in the growth of all countries throughout the world. Nigeria has been identified as having energy issues as a result of poor maintenance of hydro and thermal energy generating stations. As a res

Lassa fever (LF) is caused by the Lassa fever virus (LFV). It is endemic in West Africa, of which % of the infections are ascribed to Nigeria. This disease affects mostly the productive age and hence a proper understanding of the dynamics of this dis

The vast majority of spiral antennas are fed from the inside ports, near the center of the antenna. This paper will describe the radiation from a 4-arm conical spiral that is fed from its perimeter. It will be shown that higher order spiral modes can

The sinuous antenna is a bidirectional, frequency independent antenna. To achieve unidirectionality, a lossy cavity is employed, but at the cost of efficiency. This paper proposes a minimally lossy cavity that improves the efficiency performance. To

Two approaches for mounting spiral antennas on a typical ground vehicle are considered. Firstly, a cavity-backed aperture is flushed in the vehicles body. Secondly, spiral antenna is mounted in front of the vehicle. While the former approach is utili

Humvees are typically furnished with a wide range of antenna systems commonly mounted on the roof or bumper of the vehicle. While antennas mounted in these locations may have good performance, they both (roof and bumper) have limited room for additio

The characteristics of wave propagation for vehicle mounted sources over various grounds are investigated in this paper. Three different antenna positions on a simplified Humvee model were studied including sources on the roof, at the rear, and at th
