Abstract
Gain Augmentation of a HMSIW based Equilateral Triangular Antenna using CRSF FSS Superstrate
Highlights
With the ever increasing demand for wireless based communication devices, antennas suitable for such applications are in utmost need
This technology replaces the conventional use of metallic waveguides by upholding their advantages like high quality factor and high power handling capability and yet providing a perfect platform for system-in-package or system-onsubstrate at large wherein several electronic components can be mounted on a single substrate [1,2,3,4,5]
Even though the classical waveguide technology still remains as the main stream for designing different microwave and millimeter wave systems, it is less suitable for low cost, mass production owing to being tedious, expensive in post fabrication tuning and assembling and it is where substrate integrated waveguide (SIW) technology fills in as it allows low-cost fabrication facility with superior quality performance
Summary
With the ever increasing demand for wireless based communication devices, antennas suitable for such applications are in utmost need. Frequency selective surface (FSS), the wireless counterpart of filters in microwave engineering, is very popular in communication domain owing to their ample use in antenna systems for on-board satellites or deep space exploration vehicles and in radomes. Hosseini et al [23] showed the gain enhancement of a V-band planar antenna with frequency-selective-surface as superstrate at 60 GHz wireless band. The authors have designed an equilateral triangular antenna resembling half-mode substrate integrated waveguide (HMSIW) structure to operate at 6.5 GHz resonating frequency for wireless communication systems. Radiation taking place from the PMC edge corresponds to fundamental TE101 mode at 6.5 GHz. A coupledresonator spatial filter (CRSF) frequency selective surface (FSS) is placed above the parent antenna for gain enhancement of the later. The various antenna parameters are experimentally measured and compared with those of the simulated ones
