Method of Moments (MoM)/Green’s function formulation is developed for the analysis of electromagnetic radiation from planar rectangular microstrip antennas with different feeding techniques.
1 Introduction The Linearly Tapered Slot Antenna (LTSA) as shown in Figure 1 is very important for the millimeter wave and and microwave antenna applications [1]. Method of Moment (MoM) analysis of the antenna was first presented by Johansson and Janaswamy [2-3].
The method of moment (MoM) has been proposed as a technique of design for the cavity-backed slot antenna [2], [4]. It analyzes the antenna as a boundary value problem which is a set of integral equations for the electric field distribution on the slot and current distribution of the feed line. These analyses RESONANT LENGTH CALCULATION AND RADIATION PATTERN ... pattern of longitudinal shunt slot in rectangular waveguide using 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 ...

For example, placing such a slot antenna in close proximity of a large metallic object, such as a vehicle, can significantly change the input impedance and radiation patterns of the antenna. An accurate moment method model for the tapered slot antenna A moment-method model is presented for the radiation characteristics of the tapered slot antenna. It overcomes the shortcoming of an earlier theory. The method is rigorous for the air dielectric antennas. For dielectric-supported antennas, the method is approximate but accurate.

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 Design of Slot Antenna for Wideband Applications Design of Slot Antenna for Wideband Applications ... namely microstrip patch antenna and microstrip slot antenna. The slot antennas can be fed by microstrip line, slot line and CPW. In this paper, we presented the ... which is based on the method of moments. II. ANTENNA STRUCTURE A high-gain and high-bandwidth waveguide fed longitudinal ... Later in 1995, Sangstar and Wang presented an entire domain moment method analysis of an omni-directional linear array antenna. In 2004, Bastani and Mohassel presented analysis of planar slotted-waveguide array antennas with longitudinal slots using the method of moments. The effects of various mutual couplings, thickness of the waveguide walls ...

Modal expansion method is also applied to slot coupled microstrip antennas in [4]. Input impedance calculation of slot coupled microstrip antennas using transmission line modeling is presented in [5], [6]. They also show good agreement with the measured results. Thirdly, moment method analysis of this antenna is explained in 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.
