“…This type of antenna is flexible to realize CP operation with wide axial ratio bandwidth and flat gain bandwidth. Its detailed radiating mechanism has been systematically analyzed based on the theory of the transmission line model [13] and the reciprocity method [14]. Based on this idea, it is possible to design dual-band CP radiation.…”

In this paper, a reconfigurable circular-ring feed patch antenna for polarization diversity applications is proposed. The reconfigurability is realized by using only two p-i-n diodes which are inserted into the circular feed ring of the aperture-coupled patch antenna. With the help of the p-i-n diodes, the polarization of the antenna is able to be altered among 45° linearly polarized (LP), left-hand circularly polarized (LHCP), and right-hand circularly polarized (RHCP) states. A fully-functional prototype is fabricated and measured. The measurement agrees well with the simulation and three polarization states are obtained. Owing to the merits of tri-polarization diversity, low profile and simple structure, the proposed design is a great candidate for future wireless systems.

“…To generate a circularly polarized wave, the aperture could be a cross-slot through which a hybrid feed composed of several meandered strips can couple energy to the radiator. The hybrid feed [1] is intended to simulate a sequential rotation effect to increase the axial-ratio bandwidth. It is equivalent to realize the 0 o -90 o -180 o -270 o phasing network [2].…”

A dual-band aperture-coupled CP microstrip patch antenna is presented. It contains only one radiator and one cross-slot. The vertical and the horizontal slot are of equal length which is about 1.0 to 1.5 times the side-length of a square microstrip patch antenna. It is found that the current on the patch flows sequentially in +y, +x,-y, and-x directions on the lower band (centered at 2.55 GHz) and flows along the four diagonal directions of the patch on the upper band (centered at 3.7 GHz).
