A novel method of producing multiple axial and tilted beams using eight feed double square loop (DSL) antenna is proposed. With varying permittivity value of dielectric substrate, the DSL antenna produces multiple beams and steer each of the beam produced at step of 45° throughout the 360° of space, thus offering wide range of option for any modern wireless device integrated with this antenna to focus...
A beam switched loop antenna with eight symmetrical feeding ports is proposed for beam steering applications. The feeding ports when excited one by one generate eight steerable tilted beams capable of covering complete space in front of antenna. The return loss, polarisation and all other antenna parameters stays the same for all the eight feeding configurations. The directivity of the antenna for...
A circular loop antenna with feed points on the loop is proposed. This antenna is envisaged to be useful for some beam steering applications. An example of this antenna with 8 feed points is analyzed. The eight feed points are placed symmetrically on the loop, which when excited one at a time steer the beam in eight different directions at steps of 45deg. Apart from the direction of the beam, the...
Single arm rectangular spiral antenna with four open circuit switches over a high-impedance surface (HIS) is proposed for pattern reconfigurable applications. The HIS plane without vias is utilized to achieve a low-profile antenna design with a net thickness of 5.08 mm. This is equivalent to ~ lambdao/17 for the intended operating frequency of 3.3 GHz. By using the possible sixteen switching combinations...
