A compact high-gain parasitic patch antenna with electronic beam-switching

Abstract

<span>A high beam steering antenna using HPND PIN Diode is proposed with a capability of steering its beam into three different directions -40 º, 0º and 40 º with respective switching condition. The reconfigurable parasitic antenna consists of a driven element and two reconfigurable parasitic elements, is designed with operating range of 9.5GHz. The parasitic elements act as reflectors or director depending on the switching conditions. Both parasitic elements are connected to ground plane via shorting pins. The reconfiguration is controlled by the two HPND PIN Diode switch that embeds to the parasitic element. An average gain value of 8dBi is achieved at all reconfiguration scenarios. All the simulated design has been carried out using CST software.</span>

A 2 shape slot microstrip patch antenna for global positioning system satellite communication applications

“…The compact size of the proposed radiating patch is 28 x 28 mm 2 with the ground size As shown in Figure 2, the proposed antenna has a horizontal "2" shape slot at the upper size of patch. The slot is introduced at the passion P1 = 4.3 mm and P2 = 3.7 mm from top left size of the patch [41], [43]- [46]. The depth of each branch of "2" shape slot is maintained by S5 = 2 mm.…”

Wide to multiband elliptical monopole reconfigurable antenna for multimode systems applications

“…Reconfigurable antennas can have frequencies switching or tuning [9][10][11][12][13][14][15][16][17][18][19] and also changing its radiation pattern or beam steering [20][21][22][23]. Most of the reconfigurable antennas can be used in cognitive radio systems, where most of them are having wideband to narrowband reconfiguration.…”
