Seavey Engineering has perfected improved microstrip arrays. These arrays have increased RF bandwidth and are simple to fabricate. Passive parasitic elements are placed in front of each patch element. The RF distribution network is incorporated on the same circuit board as the patch elements. The array comprises a single printed and etched board with a low-cost set of parasites spaced above the board. Most arrays of this type incorporate sealed, thermoformed ABS covers for environmental protection.
Designs always use the lowest cost dielectric materials for the requirements at hand. For lower frequency applications, we have pioneered in the use of commercial polyphenylene oxide dielectric substrates. This material is low cost, lightweight and is compatible with standard plating, printing and etching methods. We also routinely use FR4 and all varieties of teflon-filled glass laminates.

In many designs, air-spaced patch elements are used extensively. This technique eliminates all dielectric material, with resulting cost savings.
All arrays are designed using computer-based methods. Performance analysis is done using proprietary array modeling programs. Circuit artwork is done directly using Autocad. Machined features are also on Autocad. Arrays can be designed and built very rapidly using these established methods.
A T-Tech Quick-Circuit board prototyping machine is on hand for quick-reaction projects.
The following flat plate arrays are representative of the hundreds of designs carried out to date.
