Quad Band Notched Antenna for UWB Applications.
Article in Press
In this paper a U shaped compact microstrip patch antenna is studied. A CPW feed line is used to excite the antenna. The antenna has a dimension of 24 x 28 x 0.787 mm3. Ultra wideband characteristic is obtained between 2.6 GHz to 12.6 GHz. Four notches are introduced by incorporating Complementary Split Ring Resonator ( CSRR), metallic ring in the bottom plane an using CRLH structures in the ground plane.. The antenna...

A Novel Modified Hexagonal Fractal Antenna (HFA) with band notches for WLAN Rejection.
Article in Press
In this paper, a hexagonal fractal antenna is proposed for wireless applications. The basic shape of the fractal antenna is a hexagon which is modified by inserting smaller hexagons along the periphery of the generator structure. The proposed antenna exhibits a bandwidth of 7.5 GHz in the frequency range of 3.3-10.8 GHz. The band notch for WLAN rejection at 5.75 GHz is obtained by etching hair-pin slot in the feed...

This paper presents a comparison of the performance of an electric power operated yam pounding machine to traditional (manual) method of pounding yam using mortar and pestle. The comparison was done based on the pounding time using the two methods on different yam species. Selection of yams for the test samples was done randomly from new and old yams. The machine consists of a metallic casing with a variable speed...
Measurement of Electromagnetic Radiation (EMR) Pollution in the Radio-frequency Band in Minna
Article in Press
RF radiation exposure from cell phones and GSM towers has heightened general concern over any device that may be perceived as a “radiation†source. While there are safety guidelines on the Exposure to RF radiation, no measurements have been conducted to assess the level of human exposure with respect to internationally accepted MPE limits in the vicinity of any base station in Minna. In this paper, RF field levels in...
