## A no¨el dual-frequency design of a single-layer, single-feed circular microstrip antenna with an open-ring slot s demonstrated. The open-ring slot is embedded close to the boundary of the circular patch, and has a small spacing between the two open ends of the slot. By selecting suitable widths o

Figure Reflection coefficient as a function of the frequency and the resolution interpolation conductivity was chosen in order to obtain a normal theoretical reflection coefficient of 0.001% s y100 dB. Results for the reflection coefficient as a function of frequency are presented in Figure . ## 6
The characteristics of a slot-coupled circular microstrip antenna with chip-resistor and chip-capacitor loadings are studied. With a chip-resistor loading, a significant decrease in the resonant frequency of the microstrip antenna is achie¨ed, which can result in a large antenna size reduction, and
Dual-frequency operation of a single-feed circular microstrip antenna with a pair of arc-shaped slots is demonstrated. Typical designs of the proposed antenna with the frequency ratio of the two operating frequencies ranging from 1.38 to 1.58 are implemented and studied. The frequency ratio can easi
