Custom antenna design is essential in the development of electronic devices to ensure they perform optimally in their intended environments.

While off-the-shelf antennas might offer convenience, they can often underperform when integrated into specific devices. Factors such as mechanics, metals, plastics, and other variables can contribute to this discrepancy. For instance, even if a commercial antenna has impressive specifications, its performance might be compromised in our device because our ground plane shape and size differ from those specified in the manufacturer’s datasheet. This can negatively impact impedance matching, efficiency and gain pattern.

When the system is implemented on a PCB, considering the antenna to be directly printed onto it can be advantageous. This approach not only eliminates additional costs but also ensures the antenna is integrated efficiently, optimizing its performance with the entire system and mechanics.

Sometimes, design requirements necessitate antenna arrays, with two primary types:

  1. Antennas with a Feeding Network: This design is often employed when there’s a need for a higher gain and a narrower beamwidth. The beamwidth can be focused on the azimuth, elevation, or both planes.
  2. Phased Array Antennas: In this design, each element or group of elements can have controlled excitation, adjusting both the magnitude and phase. This allows for dynamic control over beamwidth, sidelobes, and offers electronic scanning capabilities of the main lobe. It also provides for null steering, especially useful when dealing with interferences.
  3. MIMO Radar Antennas: In MIMO radar systems, including those using Frequency Modulated Continuous Wave (FMCW) techniques, enhancing spatial resolution without the need for an extensive number of transmitters and receivers is crucial. Common techniques for such radars include Time Division Multiplexing (TDM). For optimal target detection, it’s important to ensure similar gain and phase patterns for all antennas, whether transmitting (Tx) or receiving (Rx), across the entire frequency range.

We have extensive expertise in designing a variety of antenna arrays. Our experience covers signal processing for scanning and null steering, as well as virtual array design for MIMO radar applications.
