Abstract:Past research performed at the University of Illinois has led to a novel antenna device called the compound reconfigurable antenna (CRA). The CRA has the ability to operate at two frequencies along with the ability to change its radiation pattern in three directions. It achieves this by adding or removing electrical length to the antennas elements through the use of diode switches and varactor diodes. Other research performed at the University of Illinois has identified a novel ground plane slot structure used to improve isolation between cosited antennas. This research simplifies the CRA by using the isolating slot structure to adjust the electrical distance between adjacent elements. The frequency dependence of the slot structure adds electrical length at only one of the two operating frequencies. This allows the removal of the varactor diode which simplifies the design of the CRA. Simulations along with measurements of a fabricated device will be presented.
