- Abstract
- This article describes a dual-hand gap-filler microstrip antenna with nearly equal gain and similar radiation patterns in the 2.4-GHz and 5.8- GHz ISM satellite Internet service bands. The proposed antenna has two Y-shaped slots on the microstrip patch and is fabricated on an RO4003 substrate with a dielectric constant of 3.38 and a thickness of 0.508 mm. The dimensions of the antenna are 50 mm x 47.5 mm x 6.5 mm, and it is fed by a coaxial cable. The measured bandwidths of the antenna are 2.376-2.492 GHz and 5.425-6.055 GHz for a voltage standing wave ratio of less than 2. At 2.42 GHz. the antenna has a broadside radiation pattern with a half-power beamwidth (HPBW) of 70 degrees in the x-z plane and 80 degrees in the y-z plane. At 5.75 GHz. it has a HPBW of 65 degrees in the x-z plane and 75 degrees in the y-z plane. The measured gain is 8.37 dB in the 2.4-GHz ISM band and 8.38 dB in the 5.8 GHz ISM band.
