Enter your desired frequency (MHz) of operation (i. The radiation pattern of a microstrip or patch antenna is shown above. The simplest patch antenna uses a patch which is one-half wavelength long, so that the metal surface acts as a resonator similarly to the half-wave dipole antennas. The input impedance of an inset-fed microstrip patch antenna depends mainly on the inset distance, y 0, and to some extent on the inset width (the spacing between the feed line and the patch conductor). This antenna does not take any much extra size and can be etched on the same mobile PCB itself. PhD Thesis proposal form Discipline. The directivity of a patch can be estimated quite easily:. Dual-Band Patch Antenna This project analyzes a dual-band patch antenna, designed for mobile phones to be used as an internal antenna. what gives meaning.
