From PCB and FPC antennas to custom RF solutions, Indian design teams have several options. Here is how to choose wisely.
In modern connected products, wireless performance is only as strong as the antenna design behind it. For Indian design houses and R&D engineering teams developing IoT devices, EV systems, industrial platforms, telecom equipment, and GNSS-enabled products, selecting the right embedded RF antenna partner is a critical early decision. Unlike external antennas, embedded solutions such as PCB, FPC, ceramic, and internal antennae require close coordination between RF design, PCB layout, enclosure mechanics, and certification requirements. A poorly matched antenna can lead to signal loss, failed compliance testing, and costly redesign cycles.
As product sizes shrink and multi-band connectivity becomes standard (LTE, 5G, Wi-Fi, Bluetooth, GNSS, ISM, LoRa), engineering teams increasingly need partners who can support simulation, tuning, integration, and volume manufacturing—not just component supply.
This guide is organised into three tiers based on how each supplier is actually reachable from India:
1. Indian OEMs (embedded/custom capability)
These companies design and manufacture in India, with custom antenna design and integration support (Table 1).
| Table 1 Indian OEM manufacturers | ||||
| Company | Location | Embedded Focus | Custom Capability | Why Consider |
| Antenna Experts | New Delhi | IoT, 4G/5G, LoRa, GNSS/GPS, Bluetooth, internal, and custom embedded antennas | Moderate customisation | Strong in custom antenna development and RF engineering for specialised wireless applications |
| CSG Networks Pvt Ltd | Faridabad, Haryana | Primarily RF antennas and telecom RF products for GSM, CDMA, Wi-Fi, WiMAX, IBS, and two-way wireless communication | High—develops custom-built RF products, sub-assemblies, and non-standard RF designs | Strong Indian RF manufacturer and telecom system integrator with antenna design, custom RF engineering, and system integration capabilities |
| Eteily Technologies | Bhopal, Madhya Pradesh | IoT, 4G/5G, LoRa, GNSS, Bluetooth, internal antennas | Moderate customisation | Good option for IoT device makers needing internal antenna solutions with India sales support |
| Jagat RF Solutions | Gandhinagar, Gujarat | RF & microwave PCBs, antenna PCBs, telecom infrastructure, 4G/5G, MIMO | Moderate to high customisation | Strong telecom/wireless ecosystem player; rapid prototyping and engineering support for OEMs |
| LUISSA | New Delhi | Patch, GPS, Wi-Fi, internal antennas | Custom design available | Suitable for compact GPS/Wi-Fi embedded applications |
| Olnexus | New Delhi, Delhi | GSM PCB antennas, GPS patch antennas, and selected RF antenna solutions | Appears to offer RF product manufacturing and supply; custom capability should be confirmed | Broad Indian RF component and antenna supplier with PCB antenna offerings alongside GPS, GSM, Wi-Fi, LoRa, and other wireless antenna products |
| Raamtel Solutions | Noida, Uttar Pradesh | Value-added distributor and RF solution provider rather than an antenna OEM | Through partner brands | Acts as a sourcing bridge for imported embedded antennas |
| Smartcom Design & Solution | Bengaluru, Karnataka | Primarily custom RF antennas and microwave solutions for telecom, industrial wireless, and specialised applications; embedded antenna focus should be confirmed | High—custom antenna design, development, prototyping, and manufacturing | Strong Indian RF engineering and antenna manufacturer for projects requiring customised antenna and complete RF solutions |
| SRFS Teleinfra | New Delhi | GSM PCB internal antennas, sticker antennas, GSM, GPS, Wi-Fi, RFID, 3G/4G and 5G RF antennas | RF solutions and product customisation; specific embedded antenna customisation should be confirmed | Indian manufacturer with a broad RF, antenna, cable, and telecom infrastructure portfolio; relevant for both embedded/internal and wider RF antenna requirements |
| Synergy Telecom Pvt Ltd | New Delhi | GSM sticker antennas, internal GPS antennas, and selected compact wireless antenna solutions | RF cable assemblies and antenna solutions; custom requirements should be confirmed directly | Indian manufacturer with a broad RF and antenna portfolio, including selected internal and embedded-relevant antenna products |
| Torniek Technologies | Bengaluru, Karnataka | Primarily RF/microwave subsystems rather than commercial embedded IoT antennas | Yes | Better suited where embedded RF is part of a larger RF assembly |
| Vinsurwaves | Bengaluru, Karnataka | LTE, Wi-Fi, GSM, 5G internal antenna solutions | Yes | Good engineering interaction for integration-heavy projects |
| Xtragen Technologies | Bengaluru, Karnataka | GNSS, IRNSS/GPS, helix, patch, and specialised RF antennas; also RF and microwave systems | High—offers customised antenna design, development, and manufacturing | Strong Indian supplier for GNSS, navigation, aerospace, defence, and specialised RF applications, with Make-in-India antenna development capability |
