This paper presents the design process of a monopulse radial line slot antenna at 94 GHz for space debris detection. The paper has included the optimization process the calculation of the antenna gain through different efficiencies. Finally, a feeding network based on 4+1 pins is selected. The central pin generates the difference beam, while ... WIDEBAND PLANAR SLOT ANTENNAS - pdfs.semanticscholar.org For this antenna, Lcpw also behaves like Lf in the printed dipole antenna design, and λg and εreff are calculated, using the same procedure used for the dipole, to be 23.5mm and 1.54 (70 % er), respectively. LineCalc calculation of εreff of the CPW feed line is 1.58, which shows that the CPA antenna decreases the feed line εreff. RESONANT LENGTH CALCULATION AND RADIATION PATTERN SYNTHESIS ... Method of Moments (MoM) technique. Resonant length calculation of the slot is a critical parameter in the design of waveguide slot array antenna. All computed results are compared with simulated results. CST Microwavestudio is used for the simulation and is totally based on FIT techniques. For computation purpose MATLAB 7.0 is used. The

Connected U-Slots Patch Antenna for WiMAX Applications 3. Antenna Design Procedure This section describes the approach of designing a patch antenna using two U-slots techniques to adapt the structure to the desired interest operating frequency. The proposed antenna consists of a ground plane, a printed patch and a microstrip feeding line.
This sophisticated procedure has been used in recent years to design a few antennas for mission-critical applications involving stringent, conflicting, or unusual design requirements, such as unusual radiation patterns, for which none of …
Bandwidth Enhancement of a Printed Slot Antenna With a A printed microstrip-line-fed slot antenna with a pair of parasitic patches for bandwidth enhancement is proposed in this letter. By using the parasitic patches along the microstrip feed line, an Chapter 8 Slot Antennas - 电子创新网 The electric field is everywhere normal to the surface of the slot antenna except in the region of the slot itself. The theoretical analysis of this configuration shows that the radiation of the currents in the sheet can be deduced directly from the distribution of the electric field in the slot. Design of Slotted Waveguide Array Antenna Fed by H … planar array design and the section V represent the directivity of the planar antenna.
