“…One example is the Luneberg lens [1], which relies on a graded dielectric constant. By controlling the fill density of printed substrates, AM achieves a continuously graded slope in dielectric constant that is the enabling feature of the Luneberg lens design [2].…”

“…Low dielectric constants of commercial feedstocks limit current antenna designs, but recent research into the composition of high-dielectric feedstocks for AM opens the design space for antennas [12][13][14]. Additionally, space-filling algorithms paired with the extrusion of high-dielectric filaments, discussed in Section 2.1, allow customized dielectric constants not previously achievable [2].…”

“…Low dielectric constants of commercial feedstocks limit current AM antenna designs. Recent research into the composition of high-dielectric feedstocks and for AM opens the design space for 3D printed hybrid material antennas [1][2][3]. This research includes loading low-loss polymer matrices such as acrylonitrile butadiene styrene (ABS) with varying volumes of high-dielectric ceramic nanoparticles.…”

This chapter describes the results of additive manufacturing (AM) for a multi-band antenna that effectively replaces two with a single footprint. The antenna achieves distinct modes of operation by achieving flexibility between horizontal and vertical polarizations on transmit and receive at both S-band and X-band frequencies. Low dielectric constants of commercial AM materials limit current AM antenna designs. Research into the composition of high-dielectric feedstocks for AM opens the design space for 3D printed hybrid material antennas. We compare the performance of an AM antenna to the same prototype using traditional methods and materials.

High quality, high capability and wide overlay are desired in modern satellite communication. Many new technologies have been used in communication satellite, and multiple-beam antenna was one of them. Discussing the amplitude and phase inconsistency of the RF multiple-receiver is the most important part for the multiple-beam antenna in practical application. The influence of the channel mismatch on the satellite multiple-beam antenna system has been discussed and simulated in this paper. We have given the signal to noise ratio (SNR) to bit error rate (BER) curves at last. And the discussion results have a certain practical application value for designing the satellite system.

“…While Luneburg lenses are a well established lens design concept [1], [2] new and innovative methods for creating these structures are still being pursued [3]. A Luneburg lens is a cylindrical or spherical lens in which the focal point of any incoming plane wave is at the opposite edge of the lens.…”

In this work, a Luneburg lens operating at 15 GHz is created from water cylinders. The approach uses effective media of water and an iterative dielectric distribution method to achieve the Luneburg lens electromagnetic profile. From the approach, the focusing of energy using the proposed Luneburg lens is shown numerically. While the approach is successfully creates a luneburg lens, the losses due to the water significant.
