This paper presents a 4×4 Butler matrix as a beamforming network that is combined with a 4-elements linear aperture coupled antenna arrays to produce four narrow steerable beams. The designed array is aimed to obtain a operating frequency at 2350 MHz for LTE applications by using the Advance Design System (ADS) and CST Microwave Studio. The measurement result shows that the bandwidth for each port...
This paper discusses an active integrated microstrip antenna with multiple input and multiple output (MIMO) 2×2 element design. The active component as power amplifier is integrated with the rectangular patch antenna for gain enhancement at port 2 and port 4. The feeding technique used is aperture coupled to easily integrate the passive antenna with the power amplifier. Simulation result shows that...
A compact slot ring triangular patch antenna with stub has been designed for MIMO 2×2 wireless broadband application. This compact antenna consists of only one layer substrate; however has broadband characteristic due to the slot ring inserted to the triangular patch antenna. The MIMO 2×2 elements achieved mutual coupling suppression to lower than 25 dB by placing the single element perpendicular...
