Noยจel dual-frequency operation of a single-feed rectangular microstrip antenna with an embedded reactiยจe loading is presented. The reactiยจe loading is proยจided by a structure of two cascaded microstrip-line sections embedded within a rectangular slot cut in the patch. By selecting suitable dimension

are used to check the accuracy of the measurement technique. A good agreement between the measured dielectric constant and the reported one is observed. The results show that the dielectric constant of the material can be measured using the waveguide cavities with a good accuracy. REFERENCES 1. L.P.

A design of broadband circular microstrip antenna with embedded reactiยจe loading directly matched to a 50 โ microstrip feed line is presented. This design is achieยจed owing to the integrated reactiยจe loading, a T-shaped microstrip-line section embedded in a nearly rectangular slot cut near the patch

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 reactiยจe load.

By embedding a pair of comb-shaped slots close to the nonradiating edges of a rectangular microstrip antenna, a noยจel dualfrequency operation of microstrip antennas using a single probe feed is proposed and experimentally studied.
