The Design of Quarter-Wave EBG Antenna

摘要

The design of a quarter-wave Electromagnetic Band Gap (EBG) substrate antenna is presented in this paper. The designed quarter-wave EBG antenna was compared to a standard quarter-wave patch antenna while both antennas was fabricated using the same material. Both antennas work at the frequency of 2.45GHz. The design was fabricated using FR4 material due to its low cost, easy access and flexibility to design. The antennas was first analyzed by using simulation from the Computer Simulation Technology (CST) software before fabrication process and measured using both the Vector Network Analysers (VNA) and Anechoic Chamber Room (ACR). The results shows that the proposed quarter-wave EBG antenna was better than the quarter-wave patch antenna in terms of size and the path loss.
