A Feed Circuit-Integrated Planar Array Antenna Using Anisotropic Conductive Paste

A multifunctional antenna typified by an array antenna is composed of each substrate suitable to an antenna and a feed circuit. A multifunctional antenna has a challenge in thickness and weight because it uses the interconnecting structures as the connectors and jigs to connect these substrates to each other. Therefore, in this paper, in order to develop a thin and lightweight multifunctional antenna, a feed circuit-integrated array antenna using an anisotropic conductive paste is designed and considered in the numerical calculation and measurement as fundamental investigation.
