In this paper, a new leaky wave antenna (LWA) is introduced. The proposed antenna radiates through a dielectric aperture created by half mode substrate integrated waveguide (HMSIW) technique. A sample antenna is designed and simulated and its radiation characteristics are investigated. It is illustrated that half conical radiation pattern is provided by the proposed antenna. The designed antenna is also fabricated and its radiation properties are measured. Results show that the proposed antenna has the advantages of wide bandwidth, enhanced scanning angle and high gain in addition to low profile, low fabrication cost, low weight. Radiation patterns of antenna at different frequencies are theoretically calculated and compared with simulated ones. Good agreement between simulated and calculated results proves the validity of the theory presented for the calculation of radiation patterns. Moreover, its common features including high directivity and beam steering capability which make it suitable for millimeter-wave applications.
