Abstract

This paper investigates a compact Spider-wave hexagonal-shaped radiating stub Coplanar Waveguide (CPW)-fed multiband Microstrip Patch Antenna (MPA) for triple-band wireless applications. The proposed antenna dimension (L x W x h) is 30 x 35 x 1.6 mm(3) laminated on FR-4 dielectric substrate material with a dielectric constant (epsilon r) 4.4. The proposed antenna operates for 4th Generation Mobile Networks (4G; 2-8 GHz), 5th Generation Mobile Networks (5G; 3.6-6 GHz, bandwidth 50-400 MHz), and 6th Generation Mobile Networks (6G; Midband, 7.0-20 GHz; bandwidth >160 MHz) at resonating frequencies of 3.27 GHz, 5.89 GHz, and 8.29 GHz, respectively. It shows that the proposed antenna is highly matched to input impedance and considering reflection coefficients (|S11|) of-28 dB at 3.27 GHz,-25 dB at 5.89 GHz, and-23 dB at 8.29 GHz, respectively, for triple-band applications. This compact design can be used in modern wireless communication systems requiring operation on multiple bands.
