U-Slot Patch Principle and Design Methodology Using Characteristic Mode Analysis and Coupled Mode Theory
John J. Borchardt, Tyler C. LaPointe
Patch antennas incorporating a U-shaped slot are well-known to have relatively large (about 30%) impedance bandwidths. This work uses Characteristic Mode Analysis to explain the im…

Loop Antennas for Use On/Off Metal Ground Planes
John J. Borchardt
Many applications benefit from the ability of an RFID tag to operate both on and off a conducting ground plane. This paper presents an electrically small loop antenna at 433 MHz th…
