compact 4 element MIMO antenna for UWB
Project Area of Specialization Internet of ThingsProject SummaryWith the rapid development of wireless communication technology, there is an increasing demand for high date rates and high reliability, which can hardly be satisfied by traditional communication technology. Recently, multiple-input-multiple-output (MIMO) technology has attracted much attention for its advantages of reducing multipath fading and increasing transmission capacity and reliability. Due to the advantages of the MIMO technology, it is considered as the key technology in the 4G (LTE) and future wireless communication. However, such technology has several disadvantages like hardware complexity and electromagnetic mutual coupling due to their small size. Mutual coupling degrades the antenna performance in terms of reduction of antenna gain and radiation efficiency. Therefore, decoupling between antenna patches is one of the challenging concerns in MIMO systems.
Project ObjectivesApplication / End Goal Objective:
The main goal of this project is to fabricate MIMO antenna with reduced mutual coupling between its elements with an aim to increase the bandwidth, gain and decrease the return loss.
project will provide a low cost solution for high data rates and high gain.
Academic Objectives:
The project will involve:
- Understanding and use of HFSS
- Understanding and use of ADS
Understanding and use of circuit CAM
Project Implementation MethodMIMO antennas are basically based on the arrays of atleast two antenna elements, however, initially single element antenna was designed and fabricated before forming the array. HFSS software has been used for simulating our antenna designs. Our antennas have been designed on widely available FR4 Epoxy substrate [13][14]. With the loss tangents between 0.017-0.025, our antennas give desired results as shall be shown in the undermentioned paragraphs. About the design it is pertinent to mention aforehand that by adding L-shaped ground stubs our Return losses reduced and mutual coupling improved.
projrct will be designed on HFSS software and hardware will be made on PCB.
Benefits of the Project- Design changes with different dimensions of slots and stubs.
- UWB works in between 3.1 to 10.6 GHZ, however, future work on lower frequencies can be carried .
- Much smaller sized antennas are an important avenue in the future work.
- Substrate other than FR4 epoxy can be used to test the same antennas for results comparison.
- As part of future work, anechoic chamber will be used to test the antennas in field conditions.
- Study on UWB antennas application in Medical Field can be carried out in the future using the above designs.
Due to their small sizes, UWB antennas can be used in avionics industry. As a kick start, implementation on Drone UAVs/Quadcopters can be experimented
Technical Details of Final DeliverableMIMO (multiple input, multiple output) is an antenna technology for wireless communications in which multiple antennas are used at both the source (transmitter) and the destination (receiver). The antennas at each end of the communications circuit are combined to minimize errors and optimize data speed.
MIMO technology has aroused interest because of its possible applications in digital television (DTV), wireless local area networks (WLANs), metropolitan area networks (MANs), and mobile communications.
