In this paper, a wedge-shaped air dielectric patch antenna is analyzed using H-P HFSS to determine the impedance and radiation characteristics. The model data are compared with experimental data measured in our laboratory. This antenna provides improved performance that is desirable in a personal communication (cellular and PCS) handsets. The use of the antenna in the handset can reduce the electromagnetic field levels from the antenna to the head since the beam pattern of the antenna is directed away from the head of users when this dielectric shape is used. Another advantage of the antenna is increased bandwidth. The bandwidth is significantly improved compared to normal dielectric microstrip patch antennas.
