Abstract
This letter presents the design of a compact size ultra wideband Microstrip line feed spanner shaped patch antenna and their 2×1 MIMO implementation for ultra wideband applications. The spanner shaped patch antenna with rectangular defective ground structure on ground plane is proposed in this letter offers improved directivity, bandwidth, and return loss characteristics. The antenna system operates frequency range from 2.743–11.6 GHz frequencies for VSWR≤2. A study was performed to implement this antenna in 2×1 MIMO arrangements on the same circuit space with orthogonal polarization. The proposed antenna have Better mutual coupling and better envelope correlation coefficient are achieved.
