Radial Line Slot Antenna (RLSA) [1] is an attractive candidate for high gain and low cost circular polarized antennas. During the last decades, there has been an increasing interest in RLSA due to several reasons: the first of them is their simple structure, which makes them suitable for low cost mass production. II. Radial Line Slot Antenna Structure Figure 1 shows the structure of the antenna. A Radial Line Slot Antenna is formed by a parallel plate structure, whose height is less than half a wavelength to avoid the propagation of upper modes. A radial TEM mode is generated through a coaxial probe (or several probes). http://www.antenna-theory.com presents the analysis of slot antennas. Topics in this video: (1) Why the slot antenna radiates, (2) How is it fed (3) what is Since the magnetic slot is a balanced antenna, a 1:1 balun should be used if it is fed with coaxial cable, to avoid the possibility of feed-line radiation. As with other ground screen under the antenna. (See Chapter 9, Section 1.3.3 and Section 2.) I have seen it stated in various places that delta loops don’t require a good ground system. This is as true as saying that verticals with a single elevated radial don’t require a good ground system. Loop antennas have been popular with 80-meter DXers Abstract—We describe the design of a radial line slot array antenna with a shaped and focused near ﬁeld. The antenna is designed in such a way to control the side lobe level and beamwidth of the normal component of the electric ﬁeld with respect to the radiating aperture. The design procedure consists of two steps.

A radial line slot antenna (CP-RLSA) is a slotted waveguide planar array for DBS reception. A number of designs have been devised, but these designs have

A circularly polarised A polarization-universal radial line slot antenna has a slot plate formed with numerous slots, a frame, and a partition plate interposed between the slot plate and the frame to form an upper layer waveguide and a lower layer waveguide. A pair of first and second feeding devices are provided in a central portion of the antenna. The first feeding device has a first matching member protruding A flat radial line slot antenna having a radial waveguide is disclosed. The antenna has a front plate and a rear plate, the front plate having an array of radiating slots and an array of reflection cancelling slots formed in the rear plate.

The difference between them is due to the imperfections during the fabrication process of the antenna model. The imperfections are caused by: firstly, the radiating element, the cavity and the

An equivalent is deduced for the junction for the case where only the dominant modes can propagate in the radial and coaxial lines. The expressions for the equivalent circuit are in terms of the unknown coaxial aperture electric field.
