Three novel shapes of mushroom-like electromagnetic band-gap (EBG) structures are presented in this paper. The three shapes are based on rectangular metal strip with different combinations. The performances of the three-shape structures are studied by using both incident plane wave method and transmission coefficient approach. The effect of height and via(More)
Two novel designs for compact reconfigurable antennas are introduced for wireless communication devices. These designs solve the steering frequency problem by tracking the desired resonance frequency or by generating various operating frequency bands to be selected electronically. In the first design, the length of the rectangular defected ground structure(More)
This paper presents microstrip array antenna integrated with novel shapes of 2D-electromagnetic band-gap structure (2DEBG). Three different shapes of 2D-EBG are used for harmonic suppression, optimizing the current distribution on the patches and decreasing the mutual coupling between array elements. As a result, the performance of the antenna array is(More)
In this paper, a novel design for coplanar waveguide antenna is developed which, consists of two U-shaped slots. The antenna is named Clip. The antenna is designed at central frequency of 2.4 GHZ with input impedance of 50Ω. The antenna dimensions represent 72% size reduction than conventional microstrip rectangular patch antenna. The measured antenna(More)
A square patch antenna with both frequency and polarization reconfigurability is presented. The antenna consists of a square patch with coplanar feed on the ground plane. On thepatch side, there isa parasitic square ring that responsible for changing the antenna polarization. On the ground plane, there is a rectangular slot by changing of length of this(More)
With the progress in wireless communications techniques in recent years, a new promising concept of wireless sensor networks has received a well deserved attention by researchers all over the world. Embedded sensors offer intelligent devices and systems that are able to react to events and physical conditions of the real world. The most important component(More)
Technology has been developing day by day where satellite communication has become daily part of our life. As the technological devices are getting smaller demand for multiband operating antennas are growing faster to the consumers. This paper represents an E shaped Microstrip Patch Antenna for multiband operations in Ku band. The design has been made on(More)
