Description
Summary:The insertion of CRSR to patch antenna has made it possible to compact and simple design, and miniaturized antenna for cognitive radio. [...]the directivity of the proposed antenna is adequate with acceptable radiation properties and perfectly matches with the simulated and measured results. Notice that, the frequency of circular microstrip patch antenna depends on three parameters, which are, er dielectric constant of the substrate, h thickness of the substrate, and a radius of the patch. Since the thickness and dielectric constant of the substrate are fixed parameters. [...]the conclusion of the paper is presented in section 5. [...]another CRSR with an inner radius a2 = 7.69 mm and width w2 = 1 mm is etched to obtain a resonant frequency of 5.2 GHz as shown in Figure 3(c).
