Folded Patch Antenna

Introduction:As technology advances, the need for wireless confederacy has dramatically increased. With the growing need for wireless connection, new and modify barbels atomic number 18 desired. It is our goal to reduce the size of piece barbel for 2.42-2.48 GHz, which in like manner sleazy in manufacturing cost, space saving and easier to incorporate into handheld or small electronics. It has come to us that, flexure a patch transmitting aerial will reduce the required go up ara yet perform the desired functions. For our senior figure of speech project, our group would like to propose an idea of purposeing a folded rectangular patch advance. The folded patch antenna is omni-directional because its radiation design capable of containing a strong field polarization in any cut plane. The folded patch will be guide by a microstrip. Folded patch is a patch antenna where the rectangular patch it self will be sheepcote around a cardinal layer thick nonconductor and t he ground will be buried in mingled with the two dielectrics. Our antenna design is balanced but it endure be fed by an unbalanced transmission cable tv service much(prenominal) as the microstrip. Also, feed line impedance rinse aside be arbitrary chosen to achieve total matching impedance. However, one of the disadvantages of the microstrip is that it provides a fairly narrow bandwidth curiously for heights permittivity substrates. Also, the reason for using high permittivity substrate is because it brings great deal the reminiscent wavelength.

Smaller wavelength means smaller size antenna repayable to its relationship (antenn a size is calculated upon wavelengths) (Fig.! 1). Also because that the wavelength is this instant tie to the dimension and oftenness of the patch; therefore, patch antenna are better used at high frequency so that it can save space yet gloss over offers the above characteristics. Currently, wireless technology advances toward smaller and smaller antenna size. Products such as GPA receiver, Bluetooth receiver and...
