In this letter, we propose and study a 2-D glide-symmetric dielectric periodic structure. We demonstrate that glide symmetry broadens the bandwidth of operation achieves lower effective refractive indices when compared to non-glide configurations. These two properties are beneficial for producing graded-index lens antennas. To potential proposed unit cell, designed Luneburg operating in K- K <i...

The characteristics of multi-beam antennas with a wide angle view based on planar bifocal two-mirror, mirror-lens and lens systems optimized parameters are studied using numerical simulation by the finite element method in Kirchhoff approximation. antenna three-dimensional dielectric calculated dependence gain prototype has been measured.

This paper presents the design of on-chip micro-antennas for package-scale galvanic isolators based on RF planar coupling. A step-by-step procedure is proposed, which aims at maximization weak electromagnetic coupling between RX and TX antennas integrated side-by-side co-packaged chips to enable both high isolation rating common-mode transient immunity thanks dielectric strength low capacitive ...
