Abstract	A rectangular dielectric-metal strip composite resonator antenna with TE^x_δ01 mode is introduced. The value of 6 approaches zero for a dielectric with high permittivity. The TE^x_δ01 mode has been explored with the possibility of a radiating mode in the hybrid dielectric-air resonator antenna with good radiation efficiency and broadside pattern. Owing to special electric field distributions, the resonant frequency of the TE^x_δ01 mode is mainly determined by the dimension along the z-axis and relatively stable regardless of changes in length along y-axis. The proposed antenna has an impedance bandwidth of 85 MHz at 3.5 GHz and a gain of about 5.72 dBi. A prototype is fabricated and measured. Measured and simulated results show high accordance.
