Calculation of the Coaxial-Slot Antenna Characteristics used ... Calculation of the Coaxial-Slot Antenna Characteristics used for the Interstitial Microwave Hyperthermia Treatment Abstract. The coaxial-slot antennas are commonly used during the interstitial microwave hyperthermia treatment due to their simplicity and high efficiency of tissue heating. How does a slot antenna work? - Amateur Radio Stack Exchange If we cut a hole in an infinite conducting plane, and feed it with a voltage source across the center, we get a slot antenna: Because the slot is between the sides of the voltage source, the currents must travel around the slot. These currents traveling over a large distance are what make it an antenna and not a Faraday screen.

The length of a ground plane (Lg) and the width of a ground plane (Wg) are calculated using the following equations [7]: 𝐿𝐿𝑔𝑔= 6ℎ+ 𝐿𝐿 (5) 𝑊𝑊𝑔𝑔= 6ℎ+ 𝑊𝑊 (6) For feeding the microstrip patch antenna, there are different methods for example, feed line method, coaxial probe feeding method etc. An Introduction of Aperture Coupled Microstrip Slot Antenna An aperture-coupled design is proposed for Microstrip slot antenna to improve its radiation pattern as well as bandwidth. It is based on coupling of an aperture between the patch antenna and Microstrip slot line. The first aperture coupled microstrip antenna was introduced in 1985 by D M Pozar (4) Figure1: Aperture coupled microstrip slot antenna Microstrip Patch Antenna Design - Santa Clara University – But illustrates sizes and importance of good antenna design • Why microstrip antennas? – The patch antenna is a good place to start for antenna fundamentals With more coming: 5G (or whatever), Wireless Display, Wireless USB, etc. Slot Antenna basics | Impedance of Slot Antenna

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 Design of Slotted Waveguide Antennas with Low Sidelobes ... Design of Slotted Waveguide Antennas with Low Sidelobes for High Power Microwave Applications Hilal M. El Misilmani1, *, Mohammed Al-Husseini2, and Karim Y. Kabalan1 Abstract—Slotted waveguide antenna (SWA) arrays offer clear advantages in terms of their design, weight, volume, power handling, directivity, and efficiency. Slot Antenna Slot antennas are used typically at frequencies between 300 MHz and 24 GHz. The slot antenna is popular because they can be cut out of whatever surface they are to be mounted on, and have radiation patterns that are roughly omnidirectional (similar to a linear wire antenna, as we'll see). The polarization of the slot antenna is linear. DESIGN EQUATIONS FOR MICROSTRIP PATCH ANTENNA DESIGN ...

Open Access Coaxial Slot Antenna Design for Microwave ... slot spacing length corresponds to 0.25 eff, and 0.125 eff respectively, that was chose to achieve localized power deposition near the slots of the antenna. Nevertheless, due the catheter and its thickness also affect the performance of the antenna, according to [10], equation 4 only provides an inaccurate approximation for the design.
