| 总结: | Recent advancement in WiMAX and similar applications need the antennas
of broad bandwidth, small size, high gain, and enhanced efficiency. Microstrip patch
antennas are widely used in these applications due to advantageous features like
compactness, light weight and high efficiency. However, one of the major limitations
of the microstrip patch is the narrow bandwidth. The objective of this project is to
design, construct and fabricate a rectangular U-slot antenna for WiMAX applications
to operates at frequency range of 2.8-4.8GHz, to achieve a dual band of WiMAX
frequency. This antenna is fed by a microstrip feeding line. The antenna was
fabricated on FR4 substrate, that has a relative dielectric constant, .sr = 4.3, a loss
tangent tan 6 = 0.001 and thickness, h of 1.6 mm. Transmission feed Iine is used due
its better impedance matching capabilities than the inset feed technique. The
characterestic of each parameter of the antenna was analysed by using CST
simulation. This analysis is important to determine the effect of the each antenna
parameter to the output of the antenna. Insertion loss and return loss are two
important responses to be observed. The fabricated antenna is tested using network
analyzer. |
