abstract

  • In this work, we present a highly compact multi-branch structure multi-band antenna with a grounded coplanar waveguide
    (GCPW)-fed structure printed on 26 ×13 ×1.6 mm3 sized FR-4 substrate having dielectric constant Žr of 4.3 and loss tangent ‘ of
    0.02. In the proposed antenna, “ve branches are extended from the main radiator to provide multi-band behavior. Two branches
    are introduced at the upper end of the main radiator, e–ectively covering the lower bands, while the other three branches are
    introduced near the center of the main radiator to extend operation to higher bands. e designed antenna covers “ve di–erent
    bands: 2.4 GHz, 4.5 GHz, 5.5 GHz, 6.5 GHz, and 7.8 GHz, with respective gain values of 1.34, 1.60, 1.83, 1.80, and 3.50 dBi and
    respective radiation e›ciency values of 90, 88, 84, 75, and 89%. e antenna shows a good impedance bandwidth, ranging from
    170MHz to 3070 MHz. e proposed antenna is simulated in CST Microwave Studio, while its performance is experimentally
    validated by the fabrication and testing process. e antenna has potential applications for IoT, sub-6 GHz 5G and WLAN (both
    enablers for IoT), C-band, and X-band services.
