“…Finally, (8) considers the antenna height with the goal of keeping its footprint small. Note that for ( 6) and (7), gain values are considered on a linear scale, not dB. In future work, additional cost functions could be implemented to further lessen the antenna's footprint.…”

“…However, some level of constraints are needed as completely unrestricted antennas may not be fabricable with traditional methods such as CNC machining. Fortunately, additive manufacturing techniques such as 3D printing provide a good solution to realizing freeform antenna structures since most structurally stable designs that can be modeled in CAD tools can be 3D printed [5,6,7,8]. However, since the design space for truly three-dimensional antennas is potentially much larger than those using traditional highly constrained methods, new modeling techniques must be used to take full advantage of this increased dimensionality while making optimization of these 3D designs tractable.…”

Additive manufacturing used in combination with versatile shape generation methods can enable designers to realize unintuitive antenna designs with bespoke electromagnetic behaviors that would normally be extremely difficult or even impossible to manufacture using conventional techniques. In this paper, we present a new custom algorithm that produces arbitrary three-dimensional (3D) meander line antennas. This algorithm is used in conjunction with multi-objective optimization to create two quadrifilar helix antennas (QHAs) and one monopole antenna, all with unique electromagnetic performances. One QHA has a wide bandwidth, high broadside gain, and compact size, while the other has a dual-band nature with different radiation patterns in each band. Similarly, the monopole example is a dual-wideband design which targets Wi-Fi applications. These structures possess a meander radius that varies with height as well as conductor thickness that varies along the meander path which allows for improved antenna performance over conventional meander line antennas. An example design was fabricated and tested in order to validate the performance of the optimized virtual antenna model.
