Default Horn Antenna
View MATLAB Command Create and view a default horn antenna. h = horn h = horn with properties: FlareLength: 0.1020 FlareWidth: 0.0571 FlareHeight: 0.0338 Length: 0.0500 Width: 0.0190 Height: 0.0095 FeedWidth: 1.0000e-04 FeedHeight: 0.0048 FeedOffset: [-0.0155 0] Tilt: 0 TiltAxis: [1 0 0] Load: [1x1 lumpedElement] show(h) Fig.3.3. Horn antenna with dimensions. Task to perform. Each student must study such horn antenna properties as gain, radiation pattern, azimuth and current conduction. Prepare reports and submit them. The operating frequency of the antenna is determined by the following formula 22 F=N+10 (GHz). Here F is the frequency of the antenna, N is the student's serial number according to the journal. 23 Laboratory work # 4 Theme: Design and analyze patch antennas using the Antenna Designer app Purpose of work: Learn to work with the Matlab Simulink environment. Study the design principle and parameters of patch antennas.

Types of patch microstrip antenna. Microstrip or patch antennas find uses in applications that require low profile antennas without compromising performance. Mostly patch antennas are directly designed in printed circuit boards (PCB). The structure consists of a conducting patch and a ground plane between which is a substrate that can either be air or a dielectric such as Teflon. Table 4.1.
