Dielectric Loaded Exponentially Tapered Slot Antenna Utilizing Substrate Integrated Waveguide Technology for Millimeter Wave Applications

Abstract

Abstract-A novel compact dielectric loaded Exponentially Tapered Slot (ETS) antenna using Substrate Integrated Waveguide (SIW) technology is presented in this paper for Millimeter (Mm) wave wireless communication applications. The dielectric loaded ETS antenna and compact SIW feed are fabricated on a single substrate. The compact SIW feeding structure results in a considerable reduction in size and eliminates the unwanted radiations from feed. The proposed antenna is designed, fabricated, and investigated at 60 GHz. Furthermore, the proposed antenna design is simulated using electromagnetic software CST Microwave Studio and the comparison is made with Ansys HFSS to validate the design procedure. The measurement results are compared with simulated results.

Indoor radio link characterization studies for millimeter wave wireless communications utilizing dielectric-loaded exponentially tapered slot antenna

“…In particular, a number of SIW-based slot antennas have been reported in recent years. [10,11] These antennas consist of single layer of dielectric substrate and are fed from one end through a coplanar feed network which significantly increases the size of the antenna. [12] Furthermore, radiation from microstrip feed lines and junctions severely negotiate the low side lobe level of the slot antenna and increases cross polarization.…”

Indoor channel characterization studies for V-band gigabit wireless communications using dielectric-loaded exponentially tapered slot antenna

“…The concept of SIW technology makes it possible to realize the waveguide in a substrate and provides a sophisticated way to integrate the waveguide with MmW planar circuits using the conventional printed circuit technology. In particular, a number of SIW-based slot antennas have been reported in recent years [10, 11]. These antennas consist of single layer of the dielectric substrate and are fed from one end through a coplanar feed network, which significantly increases the size of the antenna [12].…”

Design and Analysis of Ridge Substrate Integrated Waveguide Bandpass Filter With Octagonal Complementary Split Ring Resonator for Suppression of Higher Order Harmonics

“…less expensive but offer non-immunity to the losses as well as parasitic crosstalk between lines. In order to reduce filter size and enhance the performance, several modified waveguide configurations have been developed, such as substrate integrated waveguide (SIW) [5][6][7], half mode substrate integrated waveguide (HMSIW) [8,9], substrate integrated slab waveguide [10][11][12], and ridge substrate integrated waveguide (RSIW) [13,14] in SIW configuration. SIW supersedesf conventional rectangular waveguide by its reduced width due to substrate filling.…”
