Microstrip Patch Antenna with Dual Equilateral Triangular Cut Resonators Structure for WLAN Application

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.
