Infrared transparent millimeter wave antenna based on sapphire substrate

Abstract

We describe a novel millimeter wave antenna based on sapphire substrate. An infrared transparent millimeter wave antenna and the characterization of its radiation pattern, gain, main frequency, and dielectric infrared transmission were reported. The proposed antenna was constructed from several infrared transparent dielectric materials with thin gold film array elements using a photolithographic process. Several single‐layer infrared‐transparent substrates were stacked. As a infrared transparent window, the antennas have applications in multimode communications, navigation, and detection, particularly for millimeter wave and infrared wavelength in a common aperture system.

Miniaturized Meander-Line Dipole Antenna For Short-Range Wireless Communication Networks

“…Integrating an antenna on the same substrate along with other RF components offer many advantages such as, miniaturization, cost effectiveness, low power, and high integration of the wireless modules [3]. For instance, an infrared transparent millimeter wave antenna on a sapphire substrate was presented in [4]. Another work on a sapphire-based antenna was reported in [5], where a stacked rectangular dielectric resonator aperture coupled antenna was designed for the C-band applications.…”
