“…In addition, many techniques to increase gain of CRA were proposed in [6][7][8] Mohd Taufik Jusoh is also with the Department of Electrical and Electronic, Faculty of Engineering, National Defence University of Malaysia, Kem Sungai Besi, 57000 Kuala Lumpur, Malaysia (taufik@upnm.edu.my). [9] and reactively controlled CRA in [10] were proposed to work at 2.4GHz. A mechanical approach of achieving variable beamwidth by changing the included angle of CRA was proposed in [11].…”

Abstract-A novel reconfigurable plasma corner reflector antenna is proposed to better collimate the energy in forward direction operating at 2.4GHz. Implementation of a low cost plasma element permits beam shape to be changed electrically. The maximum measured gains are 5.7dBi, 10.8dBi and 10.5dBi for the omnidirectional, single and double beam shapes respectively.Index Terms-Corner reflector antenna, plasma corner reflector antenna, plasma antenna, reconfigurable antenna, reconfigurable plasma antenna.

“…Over the last few years, a strong research effort has been dedicated to the design of more and more performing switched-beam antennas [7][8][9][10][11][12][13][14]. Nevertheless, their integration in WSN motes to reduce energy consumption and to extend motes lifetime, has not been exhaustively explored yet.…”

“…Despite the appreciable peak gain in the main lobe direction, it is rather cumbersome and presents no radiating beams in the azimuth plane. A reconfigurable angular diversity antenna using quad corners as reflector arrays and a switching control circuit is proposed in [10]. It presents a high radiation gain, but occupies a large volume and does not guarantee a uniform radiation patterns.…”

Abstract-Energy saving is one of the most important issues in Wireless Sensor Network (WSN) context. Since the communication task is the most power-consuming operation, it is quite important to achieve an energy efficient communication in order to increase the lifetime of the devices through an intelligent use of the power transmission. In this context, the integration of WSN nodes with switched-beam antennas is becoming more and more appealing due to the possibility to extend sensor node lifetime by optimizing the transmitted power.In this work a switched-beam antenna for WSNs nodes in the ISM band (2.4-2.4835 GHz) is proposed. The radiating structure consists of four identical antennas, composed of an array of two L-shaped quarter-wavelength slot antenna elements arranged in a compact and symmetrical planar structure. Thanks to a properly designed switching circuit which controls the feeding of the antenna elements, one among eight possible different radiation patterns in the azimuth plane can be selected on the basis of specific needs. Simulations and experimental results, referred to a prototype realized on a FR-4 substrate, demonstrate the appropriateness of the proposed switched-beam antenna system as hardware element enabling new power saving strategies in WSN contexts.

“…Many SBA designs with various antenna types have been developed and built so far. [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] A SBA using lens techniques is one of the promising candidates for wide-angle scanning. An excellent SBA design was given by Schoenlinner et al 1 using a homogeneous spherical lens antenna to achieve 180 scan coverage.…”

In this article, a switched beam antenna (SBA) operating in 360° multibeam azimuth steering and omnidirectional coverage modes is designed and investigated for point‐to‐multipoint datalink communication system. The SBA with a compact size of 342 mm (diameter) × 163.5 mm (height) is composed of two vertically stacked parallel‐plate cylindrical Luneberg lens antennas (CLLAs) with a low‐profile inverted‐cap shaped printed monopole placed above them. Each CLLA yields multiple highly directive beams and 180° scan coverage by implementing an arc feed array of 11‐element Vivaldi antennas at the periphery of the lens. A total of 22 fixed high‐gain beams and an omnidirectional pattern can be selected individually to scan in and cover the azimuth plane. Moreover, the desired refractive index of the lens is controlled through the asymmetric Bruggeman (A‐BG) effective medium theory and realized by using air‐filled holes of different sizes/density in a homogeneous polyethylene base. The simulated and measured results indicate that the SBA exhibits a wide impedance bandwidth over 2.5‐13 GHz, and it also possesses a 360° multibeam scanning performance with about −3 dB average crossover and tolerable gain drops over 3.5‐10 GHz band, while maintaining an omnidirectional coverage with measured gains between 0.7 and 2.7 dBi over 2.5‐8.5 GHz band.
