Two-element narrowband planar fork antenna operating at 23.80 GHz

A dual-element multiple-input multiple-output (MIMO) antenna is presented. The introduced MIMO antenna is designed for its narrow bandwidth, compact ness, enhanced diversity performance and high isolation making it a high-performing alternative for future wireless communication applications. Critical performance parameters, including radiation pattern, gain characteristics and S-Parameters, are analysed to evaluate the antenna’s efficiency and reliability while minimizing interference. The antenna functions within a frequency range of (23.34–24.20) GHz operating at a resonant frequency of 23.80 GHz with a dimension of (6.46 × 16.61 × 0.254) mm³ and a bandwidth of 0.86 GHz which makes it suitable for automatic radar systems, industrial and IoT applications.
