A compact frequency-reconfigurable slot antenna for LTE (2.3 GHz), AMT-fixed service (4.5 GHz), and WLAN (5.8 GHz) applications is proposed in this letter. A U-shaped slot with short ends and an L-shaped slot with open ends are etched in the ground plane to realize dual-band operation. By inserting two p-i-n diodes inside the slots, easy reconfigurability of three frequency bands over a frequency...
A frequency reconfigurable slot antenna is proposed. By inserting three p-i-n diodes inside a U-shaped short slot and two L-shaped open slots, which are etched in the ground plane, the antenna can achieve four states: 2.3/5.8 GHz in two single band modes; 2.3/4.4GHz and 4.4/5.8GHz in two dual band modes. The antenna has a size of 25 mm × 27 mm (0.31 λ1 × 0.34 λ1, λ1 is the guided wavelength at the...
A differential dual-band slot antenna is proposed. Dual bands are realized using meander slots in the ground plane. Compared with the conventional half-wavelength antenna, the proposed antenna has a compact size of 60 mm × 60 mm (0.36 λ1 × 0.36λ1, λ1 is the guided wavelength at f1). In order to improve the radiation performance at f1, a novel periodic structure of dual-band left-handed materials (LHMs)...
