Radial line slot array antenna

A T-antenna, T-aerial, flat-top antenna, or top-hat antenna is a capacitively loaded monopole wire radio antenna [1] used in the VLF, LF, MF and shortwave bands. [2] [3] [4] T-antennas are widely used as transmitting antennas for amateur …

Radial line slot array (RLSA) antenna design for point to ... A new type of linearly polarized Radial Line Slot Array (RLSA) antenna developed by FR-4 substrate is proposed for outdoor WLAN point to point application. The WLAN is based on the IEEE 802.1 la standard and the operating frequency range is the upper UNII band (5.725-5.875) GHz. The development of radial line slot array antenna for direct ... An offset parabolic antenna design, which then eliminates the blockage, is susceptible to physical damage as its feed is significantly exposed from the body of reflector. The radial line slot array (RLSA) type antenna is thus designed to cope with the problems encountered in parabolic antennas. RLSA is a planar antenna A Reconfigurable Radial Line Slot Array (RLSA) Antenna for ... The antenna's radiating surface is designed using a radial line slot array (RLSA) arrangement, which is fed from an aperture coupled structure. This novel feeding structure for an RLSA antenna incorporates PIN diode switches which are integrated with the feed line structure to enable the various outcomes of the radiation patterns. A Reconfigurable Radial Line Slot Array Antenna for WiMAX ...

Prototypes Development for Reflection Canceling Slot Design of Radial Line Slot Array (RLSA) Antenna for Direct Broadcast Satellite Reception.The extreme beamsquint technique to minimize the reflection coefficient of very small aperture radial line slot array antennas. Slot antenna - Wikipedia A slot antenna consists of a metal surface, usually a flat plate, with one or more holes or slots cut out. When the plate is driven as an antenna by a driving frequency, the slot radiates electromagnetic waves in a way similar to a dipole antenna.

PERFORMANCE STUDIES OF RADIAL LINE SLOT ARRAY (RLSA) ANTENNA AT 5.8 GHz ON DIFFERENT MATERIALS Omar Abdul Aziz Tharek Abdul Rahman 9.1 INTRODUCTION The type of dielectric material used as radial cavity in the Radial Line Slot Array (RLSA) antenna structure would influence the characteristics of the antenna, particularly its Radiation Pattern.
