Substrate integrated waveguide (SIW) technology that combines 3D and 2D structures has been successfully utilized due to its notable advantages, including in application H-plane horn antennas. As this type of antenna is commonly constructed on thin substrates, the E-plane radiation pattern always wide, thereby limiting achievable gain performance. In work, we propose an approach incorporates pr...

Millimeter-wave (mmWave) antennas are indispensable components in the fifth-generation (5G) wireless communication systems.

In contrast conventional substrate integrated waveguide (...

The performance of wireless communication systems is predominantly dependent on propagation environment and respective radiating antennas. Due to the shorter wavelength at Millimeter Wave (MmW) frequencies, the propagation loss through surroundings in indoor environments is typically very high. To improve the channel capacity and to reduce inter-user interference, a high gain directional antenn...
