The use of reflection and transmission models to design wideband and dual-band Fabry-Perot cavity antennas (invited paper)
TL;DR: In this paper, the authors explored how wideband and multi-band performance can be achieved in Fabry-Perot resonant cavity antennas using two design methodologies, one based on a Reflection Model of a unit cell and the other based on the transmission model of the unit cell.

A Horn Antenna Covered with a 3D-Printed Metasurface for Gain Enhancement
TL;DR: In this paper, a simple metasurface integrated with a horn antenna exhibiting wide bandwidth, covering full Ku-band using 3D printing is presented, which consists of a 3D-printed horn and a three-dimensional printed phase transformation surface placed at the horn aperture.
Journal ArticleDOI
A Method to Develop Flexible Robust Optically Transparent Unidirectional Antennas Utilizing Pure Water, PDMS, and Transparent Conductive Mesh
TL;DR: In this article, a water-based transparent reflector was used to realize low-cost, optically transparent, flexible, and unidirectional antennas for wearable body-area networks.
Journal ArticleDOI
An All-Metal High-Gain Radial-Line Slot-Array Antenna for Low-Cost Satellite Communication Systems
TL;DR: The antenna comprises a single-layer radial TEM waveguide, fully filled with air, formed between a metal ground plate and a parallel metal slotted sheet, leading to simple, low-cost fabrication, and may be useful for space and high-power microwave applications.
