Abstract
Slot-based dual-band, low-profile frequency reconfigurable (FR) multiple-input–multiple-output (MIMO) antenna design is presented here. Each element is composed of concentric annular slots that are loaded reactively using varactor diodes. Accurate placement of diodes and optimal biasing circuit configuration result in complete control on each of the tuned bands. The unique feature of the proposed work is the independent as well as concurrent tuning of each band over a wide frequency range from 1.7 to 3.8 GHz. Moreover, the competitive advantage of independent tuning and its narrow-band (NB) operation may result in better power management for RF front-end devices. The proposed antenna is fabricated using an RO-4350 substrate with board dimensions 60 × 120 × 0.76 mm3. The proposed dual-band compact antenna design is suitable to be utilized in the current fourth generation (4G) wireless standards as well as for upcoming fifth generation (5G) new radio access networks (RANs) with sub 6-GHz operation.
