The waveguide itself acts as a transmission line, and the slots in the waveguide can be viewed as parallel (shunt) admittances. The end of the waveguide is short circuited, so a rough circuit model of Figure 1 is: Figure 2. Circuit model of slotted waveguide antenna. The last slot is a distance d from the end (which is short-circuited, as seen ... Antennas: The Slotted Waveguide Antenna 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 ... Radar Basics - Slot Antennas Slot Antenna. Slot radiators or slot antennas are antennas that are used in the frequency range from about 300 MHz to 25 GHz. They are often used in navigation radar usually as an array fed by a waveguide.

Design of Compact Coplanar Waveguide Fed Slot Antenna for ... Inductive fed Coplanar Waveguide slot antenna structure is shown in figure 3. Fig. 3 Inductive Fed CPW slot Antenna (From Reference [2] ) First, the dimensions of the antenna by simulation with the aid of IE3D electromagnetic software were studied and then adjusted them by experiment. The dimension of the slot antenna is Integrated Filter Antenna Front-End modules integrating filter and antenna function which is commonly called a filtering antenna have been implemented using stacked cavities coupled byametallic iris at K-band[3], an electromagnetic horn [4] and a leaky waveguide [5] at X-band. Despite oftheir large size, thesetopologies showthat the integrated filter and antenna functions have a great

SIW Based Slot Antenna In X-Band Using Rogers/RT duroid 5880 As Substrate Results and discussion . The proposed SIW slot Antenna resonates at 11.8 GHz. Return loss (S11) at 11.8 GHz is -17.74dB. Bandwidth around 11.8 GHz is 342.7 MHz which is about 2.9 % of centre frequency.
The isolation of mainbeam and sidelobe jamming signals from the desired signal being relayed by microwave communication links is accomplished by an antijamming antenna comprising a flat radome, a curved reflector and a transmit dipole.
Differ-ent E-plane structures realised with SIW waveguide are presented, thereby demonstrating the potential of the proposed techniques as in multi-polarization antenna feeding. Waveguide filter - Wikipedia

Planar slot antenna using Substrate Integrated Waveguide technology (SIW) is proposed in this paper. SIW has all the advantages required for a small size antenna package: Low- cost, high-performance and ease of integration. The SIW antenna with tapered microstrip-SIW transitions are integrated and synthesized on a single substrate. waveguide slot Antenna for 2 4GHz - YouTube
