Frequency-Reconfigurable Circularly Polarized Low-Profile Dielectric Patch Antenna for Millimeter-Wave Applications

This paper presents a low-profile, frequency-reconfigurable circularly polarized (CP) dielectric patch antenna (DPA) for K-/Ka-band millimeter-wave (mmWave) applications. The proposed antenna employs a high-permittivity ceramic dielectric patch (DP) excited through an asymmetric cross-slot aperture, which generates the...

A Compact High-Efficiency Tri-Band CPW-Fed Millimeter-Wave Dielectric Patch Antenna for Wireless Systems

A low-profile tri-band millimeter-wave (mmWave) dielectric patch (DP) antenna (DPA) is proposed for fifth-generation (5G) and beyond wireless communication systems. Multiband operation is achieved by exciting the resonant TM11, TM31, and TM51 modes at approximately 22, 30, and 36 GHz, respectively. Crucially, these ope...
