In this article, the H-plane cross-polarization (XP) pattern diversity is realized using an air-filled recessed dielectric layer without disturbing the co-polarized (co-pol) pattern and reflection coefficient (S11) of the conventional square patch antenna. Instead of suppressing XP over the entire...
A reconfigurable patch antenna consisting of a square patch with two cross-shaped diagonal slots is presented. The proposed design approach is based on the use of two pairs of switches in order to obtain both frequency and polarization reconfigurability. Specifically, three different polarization ...
The loaded elements are parasitic to the driven patch, but are shorted to the ground plane. Conventionally, shorting pins or walls are a common technique for reducing the size of the antenna. However, deterioration in broadside radiation with high cross-polar level occurs. The proposed shorting ...
A reconfigurable microstrip patch antenna with switchable polarization is proposed in this paper. The proposed antenna consists of a nearly square patch as a radiator truncated at two corners, two small parasitic patches are connected at the corners by using PIN diodes. The impedance bandwidth and ...

In this paper, a novel microstrip patch antenna for switchable polarization is presented. The proposed antenna has a simple structure, consisting of a square radiating patch, a pair of L-shape spur-line, and a microstrip feed line. It can produce either linear polarization or circular polarizatio...
In this paper,a microstrip patch antenna is proposed to achieve circular polarization diversity.Stubs are added around two sides of the rectangle patch and connected by PIN diodes.By turning the diodes on and off,the phase difference of two orthogonal modes is changed,which lead to the novel an...

In this paper we present a suspended rectangular and circular patch circularly polarized (CP) microstrip antenna with coplanar capacitive feed. Of the two circularly polarized (CP) antennas presented here, the first antenna uses fractal geometry with center slot within the rectangular patch and other...
