Wide-Band T-Shaped Microstrip-Fed Twin-Slot Array Antenna narrow as well as wide slot antennas. When the T-shaped feed line is used, we can extend the bandwidth in proportion to the slot width. In this case, the proposed antenna leads to the im-Wide-Band T-Shaped Microstrip-Fed Twin-Slot Array Antenna Yong-Woong Jang (PDF) Connected phased array antennas for ultra-wide band Connected phased array antennas for ultra-wide band radar applications. A wideband low profile phased array using long slot aperture was recently developed for radar and EW applications. A ... BROADBAND ARRAY ANTENNA - Cobham plc to develop an array antenna with that covers the same angular sector with a narrow and electronically steerable beam. 2 DESIGN & MODELING 2.1 Design Goals (3:1) Nurad has threshold and objective design goals for the antenna array. The threshold is a 3:1 band width array. This array was designed not to push state of the art, but to start the
The waveguide slot antennas we will be discussing have longitudinal slots in the broad face of stan-dard rectangular waveguide, parallel to the length of the guide. Figure 7-1 is a photograph of a typical waveguide slot antenna, with a total of 12 slots, six on each side, in WR-90 X-band waveguide for 10 GHz operation.
However some slots and array elements are introduced into the antenna to obtain multi band response, which covers a few bands.The single patch antenna design is shown in Figure in which slots have been introduced to achieve wideband and multiple frequency...

Although wideband phased array design is a long-standing topic of interest, progress has recently been made using endflre tapered slot antennas. The stripline fed tapered slot antenna, often called Vivaldi antenna, was flrstly introduced by Lewis etal. in 1974, and later was often employed as the antenna element to build up wideband phased
2.10: MULTIBEAM PLANAR LENS ANTENNA ARRAYS 2. X-BAND CYLINDRICAL WIDE-SCAN LENS ARRAY The lens array designed for this study is a cylindrical 45-element array with three 15-element rows, which serve to provide a fan-shaped beam in the vertical direction. The photograph of one side of the lens, Figure 2, shows the patch antenna elements with dual-polarization feed lines and the Antennas: The Slotted Waveguide Antenna (Planar Array of Slots) The problem arises because the physical dimensions along the E-plane is much shorter than that along the H-plane (the slotted waveguide is long but thin). In general, a longer antenna (or longer array) produces a narrower beam. This problem can be circumvented by arranging slotted waveguides in parallel, as shown in Figure 1. Figure 1.
