Antenna Design & Manufacturing
Projects can encounter scenarios where it may be advantageous to have a custom antenna designed rather than to adopt an off-the-shelf product. This can be due to the difficulty in sourcing an exact match to meet the demands of the project, or an unnecessarily high cost for the existing design.
Powertec leverages its local and international RF engineering experts to develop fully customised antennas. Advanced manufacturing techniques, innovative testing, and exceptional cost control all contribute to deliver custom antennas that meet even the most demanding project requirements.
Custom Antenna Design
Custom designed antennas are required when peak performance is a necessity. With wireless technology advancing rapidly, ensuring optimal radiation efficiency and AAS-critical parameters such as envelope correlation have never been more important.
With business objectives and marketing claims all too often pushing the limits of engineering, designers are under pressure to maximise performance. Powertec can help meet performance objectives while retaining tight control over costs.
Our team design antennas covering frequencies from 225 MHz to 80 GHz including:
- 4G / 5G customer CPE / UE antenna
- 2x2 MIMO dual polarised antennas
- 4x4 MIMO quad polarised antennas
- C-band 3.5 GHz AAS-ready
- Massive MIMO smart antenna systems
- IoT / M2M antenna design & hardware optimisation
- Sub-600 MHz UHF broadcast antenna
- UNII band/Sub-6 GHz PTP / PMP antenna
- 6 to 80 GHz microwave band antenna
The physical production of our internal designs is conducted by leading manufacturers and offered to our clients as OEM products. Additionally our strong relationship with the world's largest RF manufacturers allows us to ODM manufacture any supplied design.
Antenna performance is always a compromise or trade-off between numerous interacting elements, all of which contribute to the end capabilities of the final design. Not taking any particular antenna type into consideration, some of the obvious examples include; gain vs beamwidth, VSWR vs operating bandwidth, and cost vs quality. Naturally, off-the-shelf products are not optimised for any one operator’s specific circumstances and in case of a large project, critical applications or significant/extended operational period it becomes increasingly important to have a tailored antenna solution that has been specifically engineered to ensure that it is fit for purpose.
Typically, designing a custom antenna for a large project results in huge financial savings when compared to off-the-shelf options, this is especially true in regards to capital outlay. Non-optimised shelf products are designed to fulfill a variety of roles and thus may be under or over engineered for the client’s purpose. Having a product that precisely meets the application’s requirements grants greater cost control in production and reduces any wasted or unnecessary performance characteristics.
OEM / ODM Antenna Manufacturing
We leverage our exceptional relationship with world leading antenna manufacturers to supply our clients with antennas that provide supreme performance while remaining cost effective. Antenna models that are offered under this arrangement are existing products that have been developed by our team and are not subject to an exclusive agreement or a Custom Designed Antenna that has been commissioned by a client for their particular application.
Antenna manufacturing is conducted in compliance with our Quality Management System and employs advanced manufacturing equipment to ensure that the high standards are continuously being met. Some of the equipment deployed in the production lines to maintain the high standards of quality include:
- Electronic Computer-Aided Design (Keysight EEsof EDA)
- Electronic Design Automation (EDA)
- Automated Optical Inspection (AOI)
- Automated X-Ray Inspection (AXI)
- In-Circuit Test (ICT)
All products manufactured adhere to the Restriction of Hazardous Substances Directive (RoHS) that limits the amount of hazardous materials used during the manufacturing of electronic equipment. This protects people, the environment and ensures compliance with European importation restrictions.
Amplifying Possibilities for Clients
Having antennas manufactured on an OEM basis grants our clients control over various aspects of the finished product. One example is aesthetics which becomes quite important in the case of CPE antennas, clients often feel it preferable to have their products branded in a specific way which is understandable considering that it is a product often installed in highly prominent positions. Antenna radomes can be moulded with tactile friendly materials and into appealing form factors, associated bracketry/stands can be customised and the client’s branding displayed. From an engineering perspective, other adaptable aspects include integrating different connectors or cable tails, improving environmental survivability, packaging, etc.
Longstanding Professional Relationships
Our company has invested heavily into building professional relationships with our manufacturing partners and the firm is dedicated to preserving and growing these relationships. There are several key advantages attained though our long term working relationships and these benefits are conferred to our clients. Our rapport and good standing leads to reduced variation fees, increasingly flexible payment arrangements and better delivery terms.
