Abstract:
With rapid progress in telecommunications, small
dimension antennas or compact antennas become
necessary. Along with the reduction in size of electronics
equipment, thanks to the development of integrated circuits,
the demand of compact antennas has increased rapidly,
especially in mobile telecommunications system and WLAN
applications. Even though the dimensions are reduced, the
not be significantly degraded. The microstrip antenna is the
most recommended antenna for small equipment, especially
when a built-in antenna is required. Theoretically, when the
dimension of the antenna is reduced, the efficiency and the
performance of the antenna will decrease. How much the
performance decrease depends on how small the antenna is.
With regard to this problem, the objective of this paper is to
design a compact microstrip patch antenna at 2.4 GHz for
WLAN applications in order to see the effect of the rformance. Analysis
method used to design the antenna is to apply the
transmission line model to determine the length and width
of the antenna, where the first antenna is the size of 39mm
long and 47mm wide and the second design produces
antenna with 28.6mm long and 37.7mm wide. A comparison
in terms of size and performance is made between two
designed antennas and a trade-off must then be realized
paper, a compact microstrip patch antenna is designed and
IE3D software. Its performance is then measured in terms of
its gain, bandwidth and polarization. Along with the
antenna miniaturization, several important parameters
found to decline, although the two antennas are still able to
maintain performance and received good level of efficiency
at a frequency of 2.4 GHz for WLAN applications.
