In this paper. three proposed microstrip patch antennas are
studied. AI1 of thcse are simpler in construction than a
traditional wide band patch antenna. The E-shaped antenna is
realized when two slots are inserted symmetrically into the
radiating edge of a normal rectangular patch antenna. tigures
1,2. The length and width of the slot play are important in
achieving satisfactory performance [5,6j. In the other form,
the broad bandwidth can be achieved by electromagnetically
coupling two shorted coplanar patches. where one is driven
and the other parasitic. It should be noted that the parasitic
patch could be either circular or rectangular. while the driven
patch is fixed as rectangular in design [7]. Measured
impedance bandwidths for the new designs will be presented.
and comeared with simulations.
