“…Clear and sharp images lead to accurate diagnostic and avoid false treatment. Increasing the number of radiating element applied could enhance the performance of antenna arrays in imaging and treatment . In this research, the proposed UWB parasitic array structure which is combined with coaxial feed even recorded the maximum gain up to 9.4 dB.…”

A high performance of coaxial feed ultrawide band (UWB) array antenna with parasitic element is proposed in this article. The 4 × 1 array antenna consists of four identical copper circular patches are appropriately connected using quarter‐wavelength transformer transmission line. The array elements and its feed network are properly optimized to have a high‐gain performance over wide range bandwidth frequencies. Introduction of semicomplementary copper parasitic element with copper partial ground technique are applied in this proposed antenna to obtain optimum large bandwidth. Taconic associated with 2.2 dielectric constant and thickness of 1.6 mm is used as the antenna substrate. Less complicated fabrication methods is possible due to the feeding network placement is on the same level with the antenna patch elements. The performance of the designed antenna evaluated in term of return loss, bandwidth, radiation pattern, directivity, and gain. The proposed antenna recorded reflection coefficient less than −10 dB started from 2.5 to 12.6 GHz which fulfilling the requirement of UWB. Dimensions of 80 × 45 mm2 and maximum gain of 12.12 dB made it as small and high gain UWB antenna. The antenna exhibits a stable gain from 3.4 to 12.12 dB over the operated frequencies and has 83% of usable fractional bandwidth. The proposed antenna performance finds it very suitable to be applied in human brain microwave imaging. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:649–653, 2015

“…This method allows for tracking many objects at the same time and makes it possible to locate them with the accuracy of several dozen centimetres. The disadvantage of this method is the necessity of having at least three receivers so that the measuring system could determine the position in space in an unprecedented way [2].…”

This paper discusses two ways of measuring the distance between the transmitter and the receiver using UWB technology, then identifies their advantages and disadvantages. The method of calculating the position is presented together with the method of predicting errors based on room geometry. The hardware configuration of the transmitter and receiver systems included in a location system based on UWB technology is explained. Bluetooth technology is discussed, which is used to connect the location system with the environmental monitoring system.
