Antenna Simulation

Antenna Simulation Analysis is at the core of what we do here at our Singapore office at BroadTech Engineering.Antenna Simulation
Our engineering design consultants and EM field simulation consultants and antenna design consultants at BroadTech Engineering can take advantage on the advanced features of ANSYS HFSS & ANSYS RF Option to accurately numerically model the functional performance of all antenna design iterations, as well as the various interaction scenarios between the different wireless data transmission equipment systems functioning within the warehouse premises way before financial resources are committed to the building of the actual physical structure, has even began.

Any functional performance issues or interference in the wireless signal transmission will be identified and highlighted in the engineering FDTD simulation analysis.
The comprehensive results from the engineering simulation are able to help our client to ensure that the signal/data transmission performance of the antenna prototype design is able to meet the design requirement
This also helps to facilitate proper frequency allocation planning, systematically define actual operational input parameters and propose mitigation solutions needed to ensure proper on the field operation for the simultaneous normal functioning of all wireless signal transmission systems

Overview

Simulating Wireless Systems

An Engineering Simulation-driven product design of wireless communication systems to accurately predict performance in complex and dynamic user environments must begin way earlier on in the ideation and concept design stage of the wireless system level design.

Proliferation of Wireless Technology In our Daily Lives

As wireless antenna communication systems increasingly proliferate in our globalized interconnected environment that we live in, the opportunities for the occurrence of electromagnetic interference (EMI) and degradation of signal communication performance significantly increases.
The outcome could range from minor temporary annoyance with regards to personal entertainment to a disastrous life and death scenario where it could involve failure of a passenger airliner or military defense hardware.
By having a means to use a specialized electromagnetic field simulation software to reliably predict and determine where electromagnetic interference (EMI) is most probably going to happen way early on in the engineering development cycle, engineering design teams and engineering consulting firms can effectively avoid EM interference issues, lower the financial expenses incurred to re-mediate technical problems later and effectively helps in risk management.

Importance of Simulating for Electromagnetic Interference (EMI)

By to absolute necessity, the engineering of Antenna design needs to include the inclusion of the impact of other nearby located wireless transmission equipment and other external sources of Radiofrequency (RF) signals in the surrounding environment which is not included as part of the engineering system under intentional design consideration.
The Failure to design and account for the intended usage environmental conditions environment will very likely cause a wireless antenna design that performs perfectly in a controlled lab test environment but immediately fails in performance degradation when actually deployed in the actual environmental conditions.
This can result in the unexpected requirement to implement expensive interference mitigation counter-measures and possibly cause product and business strategies to failed heavy financial losses.

ElectroMagnetic Interference (EMI)

These signal transmission systems must function reliably in the frequent in close proximity to other closely located wireless antenna technology & systems which have a high probability to induce EM interference and performance degradation of the wireless transmission.

Radio Frequency Interference (RFI)

Unintentional sources of radio frequency (RF) interference (RFI) present in the daily environment also must be taken into account to achieve a robust wireless system design.

Simulation of Complex Antenna Environments

BroadTech engineering offers our client world-class electromagnetic simulation and Engineering design solutions that encompass the core disciplines. This includes the utilization of ANSYS HFSS for electromagnetic (EM) wave field simulation analysis and antenna design & placement.
Using the use of ANSYS RF Option in the circuit and system simulators, we have the capability to accurately predict the real-time performance of wireless sensors when integrated to the Antennas installed
Our engineering simulation of the antenna performance is able to seamlessly integrate all the individual technologies from the electromagnetic and circuit system to accurately simulate the data transmission performance of all the presently deployed wireless antenna systems in the complex deployment environments.

Electromagnetic Interference (EMI) of Nearby Co-deployed Antenna

As the quantity and variants of wireless transmission equipment consistently continues to proliferate the antenna market, it has actually becomes even more crucial to carefully assess the negative Electromagnetic (EM) impact of nearby co-located antenna transmission equipment on the actual wireless signal transmission performance of the system being designed if proper performance is to be expected in deployed locations.

Advanced Multifidelity Simulation Modeling

Our engineering Antenna simulation uses FDTD simulation model libraries which is compliant with industry standards for many types of wireless systems. The advanced multi-fidelity simulation modeling strategy that we adopt offers extremely useful engineering simulations capable of accelerating early engineering design decisions even when only an incomplete set of design and performance parameters is made known.

Application of Wireless Communication in Logistics

For instance, a modern automated warehouse might receive client online orders and dispatch them via sophisticated delivery drones.
The logistic warehouse heavily depends on a multitude of RF radio communication devices to wirelessly link the various segments of this order request and order fulfillment workflow process flow.
Wireless antenna systems in the fulfillment warehouse encompasses the use of advanced radio frequency identification (RFID) tags and handheld RFID readers for inventory management & control, wireless data transmission links operating in various unregulated radio frequency bands to transmit and receive command signals to the autonomous android robots and remotely independently controlled flying drones, Global Positioning System (GPS) for geo-positioning data , and internet Wi-Fi and Bluetooth® data connectivity between different mobile devices.
In addition, various other sources of RF signals, such as handheld radio devices which were utilized for seamless 2-way communication between employees in the logistics warehouse, will inevitably negatively impact the performance of the wireless data transmission channels deployed to keep the normal operation of the warehouse facility.

In such a dynamically interconnected and complex wireless data signal environment, there are naturally several cases for signal interference to occur and deteriorate the functional performance of the wireless antenna system.
Using engineering simulation at the very early development phase of the warehouse’s wireless data communication systems can assist in the identification and prevention of costly system downtime before the physical system has been actually deployed on the field.
