Improvement of microstrip patch antenna gain and bandwidth at 60 GHz and X bands for wireless applications

摘要

A method has been proposed to simultaneously enhance the gain (14 dB), bandwidth (BW) (12.84% of the operating central frequency) and efficiency (94%) of a microstrip patch antenna. The antennas have been designed based on the patch size improvement technique to improve the fabrication tolerance. The designed prototypes have been fabricated by conventional low cost printed circuit board etching method and tested at X-band (8-12 GHz) and 60 GHz band (57-66 GHz) frequencies. Antennas' overall performance is maintained across their operating frequency range. The tested antennas for 60 GHz band convince the requirements for multi-gigabits/s data rate wireless local area network and wireless personal area network applications recommended by IEEE 802.11ad and IEEE 802.15.3c standards. In all cases the simulation and the measured results are in good agreement.
