vestigated numerically and experimentally. We have verified experimentally that as far as the impedance bandwidth of a /2 patch antenna is concerned, it is better to use a magneto-dielectric substrate as introduced here rather than a dielectric substrate. The measurements indicate that the antenna e

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
## Abstract An arrowβshaped microstrip antenna with a pair of narrow slots embedded near the nonβradiating edges gives wide impedance bandwidth. The experimental and simulated (IE3D) results show that antenna bandwidth is βΌ3.5 times that of a conventional patch with the added advantage of reduced a
