A radiation pattern reconfigurable antenna for WLAN applications is proposed in this paper. The antenna consists of center monopole, a pair of parasitic elements and PIN diodes. By controlling the switch states of the PIN diodes, the antenna can be worked as a monopole antenna with an omnidirectional pattern (Mode 1), a monopole antenna with reflector providing unidirectional pattern (Mode 2 and 3)...
A conformal switchable antenna system mounted on a cylindrical surface is proposed, simulated, prototyped and measured. The antenna system is composed of several tri-polarization antennas operating at 2.4 GHz band. It is shown that this antenna system realizes a quasi-isotropic pattern without any nulls over a complete spherical surface. Specifically, it is shown that by using three tri-polarization...
In order to design wideband pattern reconfigurable antenna, a compact switchable CPW-to-slotline transition feed structure is proposed in this paper. In the slotline feed, one slot of CPW is used as feed line, and the other slot serves as open stub for matching. No other structure is involved for the transition from CPW to slotline. Base on the switchable feed structure, one CPW mode and two slot...
