Circular Polarization MIMO Antenna using Sequentially Rotated Feeding Network for WLAN Applications
This work presents a wideband circularly polarized (CP) MIMO antenna operating around 5.5 GHz. The design consists of two identical 2 2 subarrays using aperture-coupled microstrip elements. A 5 mm air gap between substrates is introduced to enhance impedance bandwidth, while a sequential phase feeding network ensures s...
