Rectangular Dielectric Resonator Antenna using Barium Strontium Titanate Sol-Gel Adhesive

A Barium Strontium Titanate (BST) Rectangular Dielectric Resonator Antenna (RDRA) was constructed on a FR4 Printed Circuit Board (PCB). The RDRA was innovatively glued to the PCB using dried sol-gel BST composite as opposed to epoxy, which has not been done before. Adhesion pull tests indicated that an average load of 161 grams can be applied before separation of RDRA and PCB occurs. The RDRA antenna gain was 3.6 dB for the RDRA in TE
1δ1
mode at 10.1 GHz.
