The advantages of microstrip antennas have made them a perfect candidate for use in the wireless local area network (WLAN) applications. Though bound by certain disadvantages, microstrip patch antennas can be tailored so they can be used in the new high-speed broadband WLAN systems.
This project concentrates on manufacture of broadband microstrip patch antennas for the 2.45 GHz ISM band and possible implementation using adhesive copper tape in research scenarios. In the course of the project, two broadband microstrip patch antennas were manufactured to adequately cover the 2.4- 2.5 GHz frequency band.
A test procedure was also devised to compare the area coverage mappings, in term of path loss, of the in-house built antennas to the commercial broadband antennas. The testing show, the in-house antennas demonstrate larger bandwidth response compared to the commercial product but commercial product has a larger beamwidth and illustrate a better coverage.
