28GHz Vivaldi Step Tapered Antenna using LCP Substrate

摘要

A 28 GHz band Vivaldi step tapered antenna using an LCP substrate (Liquid Crystal Polymer Substrate) is provided. An antenna according to an embodiment of the present invention includes an LCP (Liquid Crystal Polymer) substrate; And a radiation body located on both sides of the LCP substrate and an area open with a tapered structure. As a result, a high-gain broadband antenna can be realized by using the low loss characteristics of the LCP substrate, and the use of the step-shaped non-Valdi structure of the radiation structure can facilitate tuning and improve performance.
