Abstract: In this communication, a circular patch antenna is reported for dual- band operation based on VIAs. Initially the patch is resonating at single band with Linear Polarization (LP), and the Circular Polarization (CP) is obtained by inserting semi circular cuts at the edges of circular patch. The second band is achieved by loading the vertical metallic VIAs along the circumference of the patch antenna. The reported antenna is working at 2.4 GHz (Wi-Fi) and 3.5 GHz (5G) bands with Return Loss Band Width (RLBW) of 4.83% and 10.37% respectively. The Axial Ratio (AR) bandwidth at 5G band is 2.38% (3.31- 3.39 GHz).
Keywords: Circular Patch, Metamaterials, VIAs, CP, Axial Ratio.
Scope of the Article: 5G Communication
