Featured Antenna Consulting Case Studies

1. Design, Simulation, Manufacturing & Measurement of UWB Spiral Antennas

Objective: The objective of the project was to design a four-arm spiral antenna for UWB applications.
● Analytical design of the antenna for a frequency band of [0.5; 12]GHz.
● Simulation of the antenna on CST microwave studio in order to validate the antenna performances and adjust the design parameters using parameter sweep and transient simulation.
● Manufacturing of the PCB antenna using chemical process.
● Measurement of the antenna performances.
The outcome of the first step of the project was that the manufactured antenna presented the desired UWB bandwidth both in simulation and measurement.

 3. Metasurface Antenna Design

At BroadTech Engineering, we have done the computational simulation of metasurface antennas.
The objective was to validate the antenna’s radiation pattern and compare it with theoretical results.

● Simulation of the antenna radiation pattern on HFSS and FEKO.
The results of the simulations corresponded to the theoretical results both in term of adaptation and radiation pattern. The antennas were then manufactured giving good measurement results for frequencies of 10GHz and 20GHz.

2. Reconfiguration of the Designed Spiral Antenna

The objective was to modify the previously designed antenna in order to make it frequency reconfigurable.
Methodology :
● Proposal of two reconfiguration technics of the antenna. 1) Reconfiguration from UWB to UWB. 2) Injection of a frequency rejection in the bandwidth.
● Validation of the reconfiguration technics using the simulation software CST microwave studio (also using parameter sweep and transient simulation).
The results of the simulations corresponded to the expected behavior of the antenna allowing us to validate the two proposed reconfiguration techniques.

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.

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.
