Project Summary

Design and fabrication of an ultra wide-band combined antenna will be presented. By using the 
idea of combined antennas, a TEM horn antenna is combined with magnetic dipoles in order to achieve a good matching for this antenna. Proposing a suitable transition structure from Coaxial cable to the antenna, the discontinuity confronting the wave is reduced and finally, a bandwidth of 180 MHz to 30 GHz is obtained for this structure. Also, the fabrication results for this antenna verify simulation results. In the next step,another wideband element with smaller dimensions will be designed. The small dimensions of this element help its pattern not to deteriorate 
and not split into parts at high frequencies. Next, a dielectric lens is utilized in its aperture to increase the gain of this element. This lens increases the gain by 11 dB at high frequencies of the band. A 
bandwidth of 200 MHz to 40 GHz is achieved for this structure. The plots of return loss, pattern in several frequencies, and antenna’s gain in terms of frequency will be presented.

Project Objectives

Emerging new wideband standards like UWB imposes new demands for wideband front-end systems. First of all understanding of the specifications is needed to determine system requirements. Secondly, to design a front-end with a high fractional bandwidth requires a good knowledge about underlying theoriesand techniques. Finally, based on those studies different approaches for wideband antenna and front-end systems for the UWB bandwidth 3.1-10.6 GHz have been studied in this work. The goal is not only to find an antenna that has enough fractional bandwidth, but also to take the specifications of respective UWB services into account so that more efficient antenna solutions can be developed

Project Implementation Method

In the first phase, the literature review was carried out and multiple researches have been studied.

In the second phase, we are carrying out the simulations.

In the third stage, we will fabricate the antenna and write a report and research paper.

The project work has been divided into three members each of which will perform his duty in time and have to report their activity each week.

Benefits of the Project

Following are the some benefits of our project

• Wireless Personal Area Network (WPAN)
• Imaging Systems
• Vehicular Radar Systems
• Sensor Networks

Technical Details of Final Deliverable

The antenna consists of feedline and antenna. The antenna will be fabricated on an FR4 substrate which will then be delivered. The antenna size is large (30.x 35 x 15)cm and therefore cannot be easily fabricated. After fabrication, the antenna will be then tested in the Anechoic chamber where its radiation will be checked. SMA connectors will be connected at the end of the feed line to feed data.
