Journal ArticleDOI
Effect of photonic crystal and frequency selective surface implementation on gain enhancement in the microstrip patch antenna at terahertz frequency
TL;DR: In this article, a microstrip patch antenna with frequency selective surface (FSS) and photonic band gap (PBG) structures in the frequency range of 0.5-0.7 GHz is presented for wireless communications.
Journal ArticleDOI
Metamaterial Fabry–Perot cavity implementation for gain and bandwidth enhancement of THz dipole antenna
TL;DR: In this article, a metamaterial layer is implemented to improve radiation characteristic of dipole antenna at THz domain, which is known as Fabry-Perot cavity, and the antenna gain is increased more than 120% and bandwidth is amended around 82%.
Journal ArticleDOI
Modified planar sensor for measuring dielectric constant of liquid materials
TL;DR: In this paper, a planar U-shaped resonator for measuring relative permittivity of the liquid mediums is developed, where gap sections, coupled lines and central ring resonators are used to enhance electric fields interact with liquid under test (LUT).
Journal ArticleDOI
Completely Independent Multi-Ultrawideband and Multi-Dual-Band Frequency Reconfigurable Annular Sector Slot Antenna (FR-ASSA)
TL;DR: In this article, a novel compact multi-ultrawideband (multi-UWB) and multi-dual-band frequency reconfigurable annular sector slot antenna (FR-ASSA) is presented for wireless applications.
Journal ArticleDOI
A broad band circularly polarized cross slot cavity back array antenna with sequentially rotated feed network for improving gain in X-band application
TL;DR: In this article, a broad band circularly polarized slot antenna array based on substrate-integrated waveguide (SIW) and aperture-coupled feed is presented. But the antenna element's impedance and 3-dB axial-ratio (AR) bandwidths are from 8.8 to 10.4 GHz.
