Building the 8+8 Slotted Waveguide. We used 100mm x 50mm rectangular hollow box section aluminium with 3mm thick walls. This gives us an internal size of 94mm x 44mm. We chose to build the antenna for 2.442GHz, or channel 7, as this is close to the center of the 13 channels available 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. Coplanar Waveguide Fed Hexagonal Shaped Slot Antenna for ... fed antenna is designed which improves the radiation patterns of the antenna at high frequency [10]. An antipodal planar tapered slot antenna is designed over a Rogers RO4003 substrate, in addition a resistive layer is placed behind its conductive layers in order to minimize the backward radiation [11]. Applications of Substrate Integrated Waveguide (SIW ... This thesis is focused on some applications of the Substrate Integrated Waveguide (SIW) structure in microwave engineering. It is mainly divided into two parts, covering a dual-band high Q filter and a broadband high gain ring slot antenna, both of which are based on SIW resonators. This work ...
