| Summary: | The 2.4GHz frequency used in Wireless LAN applications. The investigations on
a new proximity microstrip antenna, which can be operated at WLAN frequency bands of
wireless communication are reported. The project presents the design of inset fed and
proximity feeding technique using microstrip antenna. The behavior of these antennas
are investigate such as return loss, radiation pattern, bandwidth, half power bandwidth
(HPBW), first null bandwidth (FNBW) and gain. The project includes the simulation
process using microwave office software, fabrication process using chemical etching and
measurement process by using network and spectrum analyzer. The inset fed antenna
produced greater return loss at -19dB while the PCMA designed gives return loss value
at -29dB. The array antenna design for PCMA including 1x2, 1x4 and 2x4
configurations. The 2x4 PCMA design is the best array configuration that produced
bandwidth enlargement up to 25 %. The Microstrip antennas with a proximity-coupled
feed enjoy a greater bandwidth as well as easier impedance matching than those with an
edge feed. The results show that the antenna has sufficient bandwidth and gain necessary
for the above frequency bands and may be used for WLAN applications. The array
configuration of PCMA gives larger bandwidth up to 25% compared to inset fed
antenna. Array configuration improved the gain of the antenna as well. |
