Cellular and mobile telephony, using earth-based repeaters, has received wide acceptance and has become an essential means of co
mmunication for business, even for the household. Cellular telephony by satellites is the wave of the future and communication systems are being designed for that purpose. The present allocated frequency band for satellites is at L-band ( 1.6 GHz). Various antennas are being examined for that purpose; one candidate is the microstrip patch antenna. Design a rectangular microstrip patch antenna, based on the dominant mode, that can be mounted on the roof of a car to be used for satellite cellular telephone. The designed center frequency is 1.6 GHz. the dielectric constant of the substrate is 10.2 (i.e., RT/duroid), and the thickness of the substrate is 0.127 cm.
Determine the (a) dimensions of the rectangular patch (in cm) (b) resonant input impedance, assuming no coupling between the two radiating slots
