A Reconfigurable Radial Line Slot Array Antenna for WiMAX ... A Reconfigurable Radial Line Slot Array Antenna for WiMAX Application 55 achieves a higher gain in comparison to the divisive broadside pattern. Figure 8 depicts the 3D simulation of the far field radiation patterns of the proposed antenna which is aligned with the measured radiation patterns as shown in figure 6 and figure 7. However, the A Reconfigurable Radial Line Slot Array (RLSA) Antenna for ... A reconfigurable beam shape and broadside radiation pattern microstrip antenna is introduced in this paper. 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 ... Design of Ka Band Downlink Radial Line Slot Array Antenna ... A Radial Line Slot Antenna (RLSA) is a novel planar array. This paper discusses the key design of RLSA, that is, the suppression of reflection in the antenna and the slot coupling control. Design of a slot-coupled radial line helical array antenna ...

The antenna structure is consist of a square radiation patch with an E-shaped slot, a modified ground plane with an inverted T-shaped strip that act as a parasitic stub and two parallel slots and a protruded strip which is connected to the …

The antenna is a radial line slot antenna (RLSA), with the slots placed on the upper plate in concentric rings. The radiating element is a slot pairPARALLEL plate slot antenna is an attractive candidate for high-efficiency and mass-producible planar phased array antennas for microwave and... Dual circularly polarized radial line slot antenna g .. INTRODUCTION Nowadays, the radial line slot antenna (RLSA) represents one of the most interesting planar radiating structures for its low costThe layout geometry of the annularly arrayed slot radiator was firstly proposed by Kelly and Goebels [1], and later improved by Ando and Goto by...
