In this paper, a simple aperture coupled half split cylindrical dielectric resonator antenna is proposed for dual-frequency operation. The dual-frequency is achieved by exciting higher order TE02¿¿ mode along with the fundamental TE01¿¿ mode. A prototype of antenna is made using commercially available Rogers RT duroid 6010 of dielectric constant 10.2. The measured gain of proposed antenna is 5.4 dBi and 5.1 dBi, respectively at first and second frequency. The proposed antenna exhibits broadside radiation and the measured cross polarized levels are below ¿¿¿18 dB. A fair agreement between the measured and simulated result is observed.
