In this paper, new design multifunction circuit, a compact microstrip antenna, microstrip filter and microstrip diplexer (Anfilplexer) have been proposed and presented. The presented Anfilplexer structures are mounted on FR4-substrate, and the simulation result shows that both compact antenna filter and diplexer resonate at the same resonance frequency 5.2GHz, which can be used for 4G wireless communication applications. A compact antenna, filter and diplexer are consisting of spiral-shaped microstrip resonators. The proposed Anfilplexer design is performed by using ready-made software package Zeland-IE3D.
