Ultra Wideband Antenna Design for Target Detection
04 Nov 2016
Abstract—In this paper, a four-element microstrip antenna array is presented. The array is composed of Wilkinson power dividers which act as feed network along with Dolph-Chebyshev distribution and four identical patch antenna elements. The array elements are properly designed to have a compact size and constant gain against frequency. The simulated results show good agreement with the measured results for the fabricated antenna array. Measurement shows that the array has a peak gain of more than 12 dBi with side-lobe level of −15 dB at 6 GHz. These characteristics make the antenna array suitable for UWB directional uses.

Antenna Design for Wireless Sensor Networks

Wireless sensor networks have been becomıng more important with each passing day. For example, Internet of things (IoTs) concept is developed actually based on WSN systems. There are many different potential and future applications of WNS such as in industry, defence or protecting nature.


One wireless sensor network node may include a wide variety of layers from physical communication layer to algorithm development. Antennas are also vital parts of the wireless sensor nodes. Due to the small size of the nodes, efficient and small antenna design is brutally challenging, many different methods, therefore, can be applied to enhance performance and efficiency of those small antenna elements.
