Abstract
Today, the state of the art antenna technology allows the use of different types and models of antennas, depending on the area of application considered. The antenna must be small enough for miniaturizing the wireless communication system, which have been extensively and rapidly used in the modern word, also the future communication terminal antennas must meet the requirements of multiband or wideband, the difficulty of antenna design increases when the number of operating frequency bands increases. Microstrip patch antennas are now extensively used in various communication systems due to their compactness, economical efficiency, light weight, low profile and conformability to any structure. This paper is focused on the multiband application of the microstrip patch antenna, the effects of different physical parameters on the characteristics of the structure are investigated, the results in terms of return loss, bandwidth and radiation pattern are given, the proposed structure can be scaled to meet different frequencies of wireless communication systems just by changing the dimension of the main antenna. An inset L-shaped feed rectangular patch antenna with dual rectangular slots etched on the ground plane is proposed and analyzed for increasing bandwidth of microstrip patch antenna. The results in terms of return loss, bandwidth and radiation pattern are given. The results show that dual wide bands are achieved and a better impedance matching for the upper and lower resonances are obtained. Simulation results for the effect of uniaxial anisotropic substrate on the return loss and bandwidth of the rectangular patch antenna using inset L-shaped feed with dual rectangular slots on the ground plane are also presented. This novel wideband proposed antenna provides a significant size reduction and can improve the bandwidth. Furthermore, comparative studies between our results and those available in the literature is done and showed to be in good agreement.
