| description | This thesis presents microstrip patch antenna IEEE 802.16-2004 standards for
microwave applications and WiMax. Narrow bandwidth (BW) is the main defect of
microstrip patch antenna in wireless communication. The bandwidth can be
improved by increasing the substrate thickness, and using air as substrate with low
dielectric constant. The antennas were fabricated using FR4 board. Two types of
microstrip antenna were used, the first was a single microstrip patch antenna and the
second was using an air-gap technique as the dielectric between two antenna boards.
The spacer of the air-gap has thickness of 2mm. It was made of wood to separate
between the two boards. The transmission line model was used to get the
approximate dimension for the design. Different parameters were obtained
depending on the simulation and measurement. The Computer Simulations
Technology (CST) software was used to simulate the design and the measurement
was executed by Vector Network Analyzer (VNA). The two designs were compared
to each other and found that some improvements were obtained on the air-gap
technique. The bandwidth was improved by 4.51 % with air-gap technique and only
1.02 % with the single patch antenna. |
