Slot-Loaded Microstrip Patch Sensor Antenna for High-Sensitivity Permittivity Characterization
Junho Yeo,Jong-Ig Lee +1 more
TL;DR: In this paper, a slot-loaded microstrip patch sensor antenna was proposed to enhance sensitivity in measuring the permittivity of planar materials, where a thin rectangular slot was etched along the radiating edge of a rectangular patch antenna fed by a microstrip transmission line, and two resonant frequencies were created at a lower frequency compared to the single resonant frequency of a conventional ordinary patch antenna.

Junho Yeo,Jong-Ig Lee +1 more
TL;DR: This study proposes a high-sensitivity microwave sensor based on an interdigital-capacitor-shaped defected ground structure (IDCS-DGS) in a microstrip transmission line for the dielectric characterization of planar materials.

Meander-Line Slot-Loaded High-Sensitivity Microstrip Patch Sensor Antenna for Relative Permittivity Measurement
Junho Yeo,Jong-Ig Lee +1 more
TL;DR: The proposed high-sensitivity microstrip patch sensor antenna loaded with a meander-line slot (MLS) was designed by etching the MLS along the radiating edge of the patch antenna, and it enhanced the relative permittivity sensitivity with an additional effect of miniaturization in the patch size by increasing the slot length.

Miniaturized Wideband Loop Antenna Using a Multiple Half-Circular-Ring-Based Loop Structure and Horizontal Slits for Terrestrial DTV and UHD TV Applications.
Junho Yeo,Jong-Ig Lee +1 more
TL;DR: In this article, a miniaturized wideband loop antenna for terrestrial digital television (DTV) and ultra-high definition (UHD) TV applications is proposed, which consists of a square loop, two circular sectors to connect the loop with central feed points, and a 75 ohm coplanar waveguide (CPW) feed line inserted in the lower circular sector.

Design of a High-Sensitivity Microstrip Patch Sensor Antenna Loaded with a Defected Ground Structure Based on a Complementary Split Ring Resonator.
Junho Yeo,Jong-Ig Lee +1 more
TL;DR: It was found that the second resonant frequency of the DR-CSRR DGS-loaded patch antenna aligned on a radiating edge with a half scaled-down patch size shows the highest sensitivity when varying the relative permittivity of the material under test from 1 to 10.
