Microstrip Patch Antennas for Broadband Indoor Wireless Systems ...

ABSTRACT
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.
