—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)
—In this paper, ultra-wideband and miniaturization, technique for the microstrip monopole patch antenna (MMPA) in wireless applications is presented. Ultra-wideband was achieved by using printed modified ground plane on a dielectric substrate with 50 Ω microstrip feed line. This technique allows the bandwidth of the MMPA to be ultra-wideband with(More)
—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)
With the advent of the current wireless communication revolution and the increase in its applications, the electromagnetic researchers in conjunction with the medical physicians take the initiative of studying the price of this beneficial technical revolution. It is the health hazards due to the electromagnetic radiation on the human body. The most cost(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)
New configuration of multiband / broadband Planar inverted F-Antenna (PIFA) is investigated. The antenna is a V-shaped patch with unequal arms coupled electromagnetically to single feed triangular PIFA thorough two unequal slots' dimensions. The six multiband operations are achieved due to the different lengths and widths of the V-shaped patch as well as(More)
