Single-Feed Highly-Directive Fabry-Perot Cavity Antenna for 60 GHz wireless systems: Design and Fabrication


In this paper, a prototype Fabry-Perot Cavity (FPC) antenna is designed and fabricated at millimeter-wave frequencies, aiming at designing directive antennas for 60 GHz wireless systems. A prototype FPC antenna is designed to have 17 dB gain at 42.8 GHz with 600-700 MHz 3dB-pattern-bandwidth and it is designed in order to be mounted on a wafer (chip). Measurement tools at millimeter frequencies and also antenna integration possibilities lead us to design an efficient feeding network for this kind of antenna. The antenna is fabricated on a quartz wafer (very low loss dielectric especially at millimeter-wave frequencies) which is coated by a thin layer of gold on each side. All the simulations on the reflection coefficient, gain and the radiation pattern of the antenna are done and compared using two most powerful EM simulators, Ansoft HFSS and Zeland IE3D and they are also compared with some measurement results for the prototype antenna. © 2010 IEEE.
