Abstract:
The necessity for wireless communication and its esoteric nature is enlarging during the two
decades. In future, it is deduced to be more challenging and elaborate with evolution of different
types of patch antenna with different structures. Nowadays, smaller size of electronic equipment
demand same size antenna element in order to place properly in the wireless devices without
changing the radiation properties of antenna. Antenna plays an important role in WLAN
communication system because it performance depend upon the quality of wireless
communication. Providing of a quality service for the recently increased demand in WLAN is a
core level concern as usually for antenna and communication devices. The WLAN is used in our
everyday life applications such as notebooks, mobile phones, routers etc. To meet the daily
increasing needs, antennas used in WLAN applications are noteworthy factor. With respect to
performance, a low cost feed network with miniaturization in size is also very important to carry
out in terms of antenna design. This thesis work focuses mostly on design and analysis of
microstrip patch antenna using split ring resonator structure as well as effects of triangular cut
resonator structure made on patch antenna to improve the return loss, gain and directivity. We
present characteristics of microstrip patch antennas on Roger RT/Duroid 5880 substrates loaded
with complementary equilateral triangular cut split-ring resonators (CETCSRRs) and study the
various effects of design parameters like size of resonator, number of resonator, location of
resonator and orientation between two resonators for WLAN applications. The proposed
antennas are designed using CST 2014 microwave studio. The simulated results represent that
the CTCSRR loaded patch antenna achieves better performance in terms of gain, directivity and
return loss. The radiation properties of a rectangular patch antenna with triangular split ring
resonator structure designed on Roger RT/Duroid 5880
