Cavity backed slot antenna array

abstract 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 Slot Antenna - an overview | ScienceDirect Topics The planar form of the slot antenna with CPW feeding is shown in Figure 11.18. Unlike the waveguide slot antenna that is excited from one side, the planar slot antenna demonstrates bidirectional radiation, which limits the application of this antenna. Alternatively, the slot may be either cavity- or reflector-backed to eliminate backside ... (PDF) SIW slot antenna for E-band communications The paper proposes novel substrate integrated waveguide (SIW) slot antenna for E-band communications. The antenna is designed at a two-layer low temperature co-fired ceramic (LTCC) substrate in 71 ...

Cavity-Backed Slot Antenna Array for the Repeater System The antenna consists. of a coaxial to waveguide transition part, a rectangular cavity, eight radiation slots in a 2 4 array, and a vertical reflector. The total dimension of the antenna is . Slots and a feeding waveguide are placed on top and bottom. side of the cavity, respectively. Cavity-Backed Slot Array | Antenna Magus Cavity-backed slots allow for very efficient low-loss structures at high frequencies, but often require complex feed structures. By using a single cavity backing for a number of slots and leveraging the modal distribution in the cavity to realize the excitation distribution of the slot array the complexities of the feed structure can be greatly reduced. DESIGN OF A HIGH-GAIN CAVITY-BACKED SLOT ANTENNA …
