✦ Synopsis

A wide operating bandwidth for a single-layer equilateraltriangular microstrip antenna can be obtained by embedding a pair of asymmetric bent slots inside the patch and inserting an inset microstripline section at the patch edge as an integrated reacti¨e load. With the proposed design, a group of three closely excited resonant modes of similar broadside radiation characteristics near the fundamental resonant mode of a corresponding simple equilateral-triangular microstrip antenna can be achie¨ed. Results show that an operating bandwidth as large as 4.5 times that of a simple triangular microstrip antenna can be achie¨ed. Details of the antenna design and experimental results are presented.

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
