PERANCANGAN DAN ANALISA CIRCULAR POLARITY ANTENNA CROSSHAIR WAVEGUIDE SEBAGAI PENGUAT WIFI ADAPTER TP-LINK TL-WN723N PADA FREKUENSI 2,4 GHZ
Abstract: Waveguide Crosshair Antenna with
reflectors which has
the function to change the radiation pattern and beam width antenna beam
so that in itself could increase the antenna gain. The amount of change
in the gain
generated by the addition of the reflector can be affected
by several things, among them is to set the size of the reflector
panel angle (α),
adjust the amount of spacing
between the driven element and reflector panel (space), and change the length
dimension of the reflector (h). The resulting radiation pattern waveguide Crosshair antenna is
directional, the signal emitted in two directions with the same magnitude. With
the addition of
reflectors, will limit the radiation pattern from being widened backward
and transmits force will be strengthened in the opposite direction, so that
one can
clearly see how
it changes the transmit antenna patterns before and
after the addition of the
reflector, the antenna amplifier is more devoted to the
working frequency of 2.4 GHz for wireless LAN ( local area network ). The
parameters that must be considered in designing antennas for wireless LAN is
working frequency. To test the speed of the download (download) and upload
(upload), conducted through speedtest.net on two different networks, namely
network UNTAN hotspot network in the faculty of engineering with download
speeds of 72.23 Mbps, 50.56 Mbps upload network and the Faculty of
Engineering at the
speed 3.05 Mbps download, upload
2.13 Mbps, which is influenced by the speed
speedtest maximum value and minimum speed provided by the ISP (internet
Service Provider).
