Abstract
A novel low profile Split and Rotated Microstrip Patch Antenna (SRMPA) with improved antenna performance is presented. The proposed antenna overcomes the limitations of the Conventional Microstrip Patch Antenna (CMPA) like low gain, less Front-to-Back Ratio (FBR) and more spurious radiation by the ground plane by a simple alteration in the antenna geometry. Its performance is mainly based on the opening angle (D) between the two arms of the antenna. Because the near-field interactions between the two arms are stronger at smaller opening angles, the current and scattering field amplitude are expected to be maximum. Therefore, for D<90° the antenna parameters like gain and directivity are improved and standing waves are suppressed in the proposed antenna. The results of the proposed SRMPA with a smaller opening angle reveal better performance when compared to that of the CMPA.
期刊介绍：
The explosive growth of wide-area cellular systems and local area wireless networks which promise to make integrated networks a reality, and the development of "wearable" computers and the emergence of "pervasive" computing paradigm, are just the beginning of "The Wireless and Mobile Revolution". The realisation of wireless connectivity is bringing fundamental changes to telecommunications and computing and profoundly affects the way we compute, communicate, and interact. It provides fully distributed and ubiquitous mobile computing and communications, thus bringing an end to the tyranny of geography.
