RF & Wireless Design, Proprietary Protocols, & Antenna Design
Indesign’s electrical engineers have experience developing wireless / RF circuits and antennas for a wide range of applications. Our engineering team has developed circuits supporting industry standard protocols (Bluetooth, WiFi, cellular, and others) and custom proprietary protocols.
Many of the applications Indesign engineers support are for short range applications and are best addressed with an industry standard protocol such as Bluetooth, WiFi, ZigBee, Thread or something similar. But often times the application requires a custom protocol and hardware to support the unique requirements of the product and application. The team also has experience with wide-area solutions such as cellphone (GSM, CDMA and LTE) and satellite (Iridium) technologies. Indesign engineers will help you select the appropriate technology for you application.
Whether you need help with a point-to-point wireless solution or have a desire to integrate IoT capabilities into your product, our team has the experience to take you from concept to ready-to manufacture design. We can engage with your team on all aspects of the wireless / RF circuit and antenna of your project. Give us a call today at (877) 561-0274 or contact us online.

Wireless / RF and IoT Design Technologies
Another aspect of RF design is solving problems dealing with unwanted RF emissions and susceptibility. From the start of your project, your electrical circuit design will be done with an eye towards successful compliance testing. We are familiar with FCC, Military and European compliance standards. We have good working relationships with qualified test labs and we’ll apply our experience to make your design compliant. We will assist with the needed certifications for your product.
Your RF circuit design needs to be produced in volume at an acceptable cost. We are experienced in working with manufacturers to develop wireless products that can be economically built and tested to a high degree of confidence needed for your product. We will work with your manufacturer during the early runs to get successful products built. We also design and fabricate factory test stands and develop their software.
- Bluetooth®, Bluetooth Low Energy, Bluetooth 4.2 and Bluetooth 5.0
- IoT WAN – LTE Cat-M1, LoRa, Sigfox, RPMA
- 802.11b, 802.11g, Wi-Fi (802.11 b/g/n)
- Embedded GPS Receivers and Antennas
- Embedded Cellular, GSM and LTE Modems
- Iridium Worldwide Satellite Transceivers
- 802.15.4, ZigBee™
- RFID Readers and Tags
Your RF circuit design is of little value until it can be produced in volume at an acceptable cost. We are experienced in working with manufacturers to develop wireless products that can be economically built and tested to a high degree of confidence needed for your product. We will work with your manufacturer during the early runs to get successful products built. We also design and fabricate factory test stands and develop their software.
Going hand-in-hand with RF design is solving problems with unwanted RF emissions and susceptibility. From the start of your project, your electrical circuit design will be done with an eye towards successful compliance testing. We are familiar with FCC, Military and European compliance standards. We have good working relationships with qualified test labs and we’ll apply our experience to make your design compliant. We will assist with the needed certifications for your product.
Proprietary Protocols
Standards-based RF solutions such as Bluetooth, WiFi, and ZigBeewill often times meet the wireless requirements for your product. Sometimes, however, these solutions cannot achieve the desired performance. Our engineering team can help you determine whether a standards-based or a custom RF protocol would be best for your application. If a custom RF protocol is needed, our team has the background and experience to design a solution that will meet the requirements of your product.
Our engineers have designed custom wireless protocols for many different product applications. Typical requirements for products we have designed include:
- Low Power/Long Battery Life
- Long Range
- Low Latency
- Miniature Size
- Antenna/Frequency Diversity
- Low Cost
- Low Error Rates
- Security/Encryption
Our designers can work with you to determine an optimal RF architecture and then create the detailed hardware and firmware design to meet your wireless specifications. We are familiar with the various compliance standards, and we will make sure your product can successfully pass compliance testing.

Antenna Design
Your RF/wireless product will need an antenna. We can recommend or select an appropriate off-the-shelf antenna, or design a custom antenna if needed. Our experience at Indesign includes antenna design and selection in the following areas:
- 2.4 GHz & 5GHz (WiFi, Bluetooth®, ZigBee®)
- 915 MHz & 868 MHz ISM bands (LoRa and proprietary)
- GPS Receiver
- GSM Cellular
- 3G & 4G LTE
- 60 kHz WWVB
- 125 kHz, 13.56, and 915 MHz RFID
- 315 MHz & 433 MHz
- 152 MHz MURS
- PCB Embedded Antennas
- And Many Others
Our experience includes designing embedded antennas, where the proximity of nearby metallic and dielectric objects needs to be accounted for. We have designed products employing antenna diversity, and also have experience with phase interferometry and time-of-arrival measurements across antenna arrays. Indesign has RF design and test equipment, including a screen cage and Vector Network Analyzers to assist with antenna measurement and characterization.
