Abstract
A dual port, slot-based multiple-input-multiple-output (MIMO) antenna is described. The antenna includes a dielectric circuit board, a metallic layer, four tapered feed horns and adjustable voltage sources. A first pentagonal loop slot line and a second pentagonal loop slot line are etched into the metallic layer. The tapered feed horns are located on an opposite side of the dielectric circuit board and are connected to input signal sources. Adjustable voltage sources are connected to varactor diodes of the first and seconds pentagonal loop slot line. The antenna resonates with circular polarization at resonant frequency in an ultra-high frequency sub-GHz range of about 578 MHz to about 929 MHz when an input signal is applied to each feedline. A dual port, slot-based single element antenna is also described.
