Abstract
In this work, a 4-element wide band frequency agile multiple-input-multiple-output (MIMO) antenna system is presented. Frequency agility is achieved by loading the antenna elements with capacitive reactance using varactor diodes. The proposed MIMO antenna is a wide band antenna with very wide tunability range between 1610 and 2710 MHz, thus covering several well-known wireless standards. Each tuned band has at least 470 MHz bandwidth. The proposed design is simple in structure with low profile antenna elements. The design is fabricated on an FR4 substrate with single element dimensions of 7.9 × 26.9 mm2 on a single board of dimensions 60 × 100 × 0.8 mm3. The proposed MIMO antenna system is highly suitable to be used in wireless handheld devices and mobile terminals within a cognitive radio platform. The antenna system is also characterized for MIMO performance metrics.
