Abstract:

The increasing demand for compact, high-performance antennas in contemporary wireless communication systems has prompted significant study into multi-frequency designs. Applications like Wireless LAN, satellite communication, and C-band services necessitate antennas that are both downsized for incorporation into portable devices and proficient in functioning across several frequency bands. This study introduces a tapered Coplanar Waveguide (CPW)-fed tiny multi-frequency antenna intended for Wireless LAN, satellite communication and C-band applications. The proposed antenna includes a projected structure of 30 × 30 × 1.6 mm3 size and has an asymmetric octagonal radiating patch. FR4 epoxy with permittivity 4.4 is used as a dielectric medium. The antenna resonates at frequencies 5.1GHz, 6.5GHz and 7GHz with the reflection coefficients of -17.73dB, -11.81dB, -11.73dB and gains of 4.83dB, 6.92dB, 8.46dB, respectively. The antenna produced a VSWR of 1.29, 1.69 and 1.69 for the respective frequencies.

Keywords:

Asymmetric octagonal patch, Tapered CPW, Multiband, WLAN, Satellite, C band.
