Keywords: 5G, radial line slot array antenna, sidelobes level, 28 GHz. INTRODUCTION Over the years, interest in mobile data have and is still experiencing an unprecedented growth. This growth is further fuelled by the emergence of new data hungry devices like e-book readers, notebooks, smartphones, tablets etc. Radial Line Slot Antennas | Request PDF - researchgate.net A radial line slot antenna (RLSA) is a nonresonant multimode waveguide slotted array. To improve the power handing capacity, we design a radial line slow wave structure which replaces a ... Prototypes development for reflection canceling slot design ... Abstract: A radial line slot array (RLSA) antenna is a high gain and high efficiency planar antenna which is suitable for direct broadcast satellite (DBS) reception. The satellite communication market commonly uses the standard parabolic dish antenna. However, the use of this type of antenna has some disadvantages.

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).
A slot array antenna which utilizes air gap waveguide as feeding structure has been proposed in[17]. Pyramidal shape pins are used for parallel plateThe slot displacement from the center line is chosen to be the same as for the case of 4- slot array (rectangular slots), since a mathematical expression... Double-Layer Radial Line Helical Array Antenna with… With rectangular aperture, the antenna can be assembled to form high gain antennas. The use of double-layer feed system ensures an equal-amplitude in-phase feed for all elements in an expected frequency band, which can improve antenna gain and aperture efficiency.

In the above electronically scanned printed arrays [1] and [3], the individual element radiates normally to the plane of the array and hence require a phase ...
In reception, an antenna intercepts some of the power of a radio wave in order to produce an electric current at its terminals, that is applied to a receiver to be amplified. Dipole antenna - Wikipedia In radio and telecommunications a dipole antenna or doublet [1] is the simplest and most widely used class of antenna. [2] [3] The dipole is any one of a class of antennas producing a radiation pattern approximating that of an elementary … Linebacker - definition of linebacker by The Free Dictionary
