We report results on the design and implementation of a low cost wireless multi-sensor system to enable the creation of smart building materials such as smart bricks. We have demonstrated a proof-of-concept device that samples both digital and analog sensor data from a number of configurable sensors, processes the data, and wirelessly transmits it to a data collection receiver with a maximum ra...

<span lang="EN-US">Recently, there is an increasing demand for high-speed wireless communication network short-range underwater communication. From previous research, most antennas produced omnidirectional radiation pattern which has lower antenna gain. There are a few considerations that need to be taken if the designed operate in water environment. This paper discusses electromagnetic p...

We propose, ‘E la carte’, an eMenu solutions employing ARM architecture is proposed for next generation dining experience. eMenu is an efficient way of catering patrons thus enriching their dining experience. The implemented design results in a decrease in the customer service time of 44% and the customer downtime by 64% .A helical antenna of gain approx 7 db is designed to provide wireless tra...

A quadrifilar helix antenna (QHA) operating at 0.94GHz is designed and realized in this paper. The designed QHA consists of four helical conductors which are excited in phase quadrature by employing a Wilkinson divider which shows good performance in return loss and transmission characteristic. According to the designed parameters of the helices and Wilkinson divider, a QHA is fabricated and me...

A helical antenna for Cellular-Vehicle To Everything (C-V2X) communications is manufactured and integrated around the car high mount stop light (CHMSL) area of a Ford SUV vehicle. The performance measured on foam pillar, ground plane vehicle, inside near field measurement system. consists three arms wrapped 3D-printed hemisphere with radius 4.8 mm. are built using commercial wire 0.127 It opera...

In this paper a particle swarm optimization (PSO) algorithm is presented to design a compact stepped triangle shape antenna in order to obtain the proper UWB bandwidth as defined by FCC. By changing the various cavity dimensions of the antenna, data to develop PSO program in MATLAB is achieved. The results obtained from the PSO algorithm are applied to the antenna design to fine-tune the bandwi...

Proof of concept of a cavity backed slot antenna based on inverted microstrip gap ‎waveguide (IMGW) technology is presented. Since the antenna is operating based on the ‎first resonating mode of the cavity, it is more compact compared to the ordinary cavity ‎backed slot antennas in which the second cavity mode is used for radiation. Furthermore, ‎the proposed antenna element introduces lower lo...
