Abstract

In this paper, a compact quad-port Rhombus-Shaped MIMO Patch (RSMP) antenna with a complete ground structure has been designed for dual-band wireless applications. The RSMP antenna has a common patch configuration and resonates at 12.9 GHz and 16.5 GHz with the reflection coefficients of -17 dB and -25.7 dB, respectively. A rhombus-shaped slot is etched from the patch to generate dual-band frequencies. Microstrip feed lines are connected to the common patch and are used to improve the overall performance of the RSMP antenna. The RSMP antenna has gains of 9.62 dBi and 9.98 dBi at resonating frequencies. The bandwidths of the proposed MIMO antenna model are 300 MHz and 350 MHz, respectively. The proposed RSMP antenna model was fabricated and tested with the vector network analyzer Keysight N9917A for validation. The simulated and measured results for the gain, reflection coefficients, surface current distribution, radiation pattern, envelope correlation coefficient (ECC), diversity gain (DG), total active reflection coefficient (TARC), and channel capacity loss (CCL) are compared, and they are agreed well for wireless applications at Ku-band for broadcasting communications.
