A PLANAR CAVITY BACKED SLOT ANTENNA ARRAY FOR ULTRA-WIDEBAND AUTOMOTIVE MONOPULSE RADARS VINAY MAGADI VIKRAM, M.S. The University of Texas at Arlington, 2010 Supervising Professor: MINGYU LU In this thesis, a wideband cavity backed slot antenna is designed for automotive-borne monopulse radar applications. Antenna Designs | Wave Computation Technologies (WCT) Cavity-backed slot antenna is using the resonance of EM waves in a slot to radiate the EM energy. The designs of the slot shapes can be various. Slotted Waveguide Antenna. Slotted antenna arrays carved on waveguides are a popular antenna in navigation, radar and other radio-frequency systems. Antennas: The Slotted Waveguide Antenna - Antenna Theory An example of a slotted waveguide array is shown in Figure 1 (dimensions given by length a and width b) Figure 1. Basic geometry of a slotted waveguide antenna. As in the cavity-backed slot antenna, each slot could be independently fed with a voltage source across the slot. However, (especially for large arrays) this would be very difficult to Cavity-backed planar slot array antenna with a single Therefore in [12] another similar double-layer cavity-backed slot array antenna in 60 GHz band was proposed, in which the diffusion bonding of laminated thin metal etching plates is adopted for
