This study describes the bending effect on an Ultra Wideband (UWB) microstrip patch antenna on the antenna performance in terms of impedance bandwidth and radiation pattern. Comparison is done between the UWB planar antenna and the bent UWB antenna. The bending effect causes shift in resonant frequencies with slight change in the impedance bandwidth. A circuit model comprising lumped elements i...

This is a revolutionary method which overcomes many of the antenna system analysis problems associated with UWB communication. By using this method, the antenna system is analyzed from the viewpoint of antenna to antenna transfer function, which makes it possible to consider the transmitting antenna and receiving antenna as a complete unit rather than individual element. The refined formulation...

The differential global positioning system (DGPS) transmits a GPS enhancement signal using a top-loaded monopole antenna in the medium frequency range. The top-loaded antenna in the medium frequency band can attain a radiation efficiency on the order of 10%. The antenna ground plane characteristics affect the antenna radiation efficiency. To improve the radiation efficiency, it is necessary to ...

In some applications which the increased bandwidth is needed, proposed antenna is one of the alternative solutions. The proposed antenna has been designed at the 2 GHz frequency. The frequency band of proposed antenna is in between (1.64-3.26 GHz) the fractional bandwi...

Introduction Recently the concept of traveling wave excitation was demonstrated for high field MRI (1). In these experiments RF excitation and reception was done by using a patch antenna, suited for this task. The disadvantage of this antenna, however, is its size. A proper patch antenna for 7 T MRI is almost as large as the diameter of the bore. This limits the location of the antenna to the e...

In this paper, a novel compact frequency-reconfigurable monopole antenna with switchable symmetric slot structure is presented. The frequency-reconfigurable capability of the antenna is achieved by using a switchable slotted structure on the ground plane. The designed antenna has a simple structure and compact size of 40X40 mm . The antenna, which supports most applicable frequency bands above ...
