Compact selective bandpass filter, based on the Rhodes approximation, is proposed using the novel modified hairpin resonators realized on a double-sided microstrip. The equivalence is presented between the hairpin resonator realized on a singlesided microstrip and the modified hairpin resonator realized on a double-sided microstrip. The footprint area of the filter is reduced by 50% with the mu...

We described the properties of microstrip band gap filter with elliptic-fractal pattern from 40 Hz to 20 GHz. It used the characteristic of the fractal and elliptic pattern to improve the performance of microstrip band gap filter. The center frequencies of gaps of the filter were about 5.5 and 15 GHz, and the band stop bandwidth of the filter can be increased by increasing the numbers of the ce...

A simple, compact, slot loaded stacked wideband microstrip patch antenna is presented in this communication. The radiating element consists of a rectangular patch with a Tshaped slot and is fed by a 50 Ω microstrip line. The proposed antenna is simulated using IE3D software, 12.32 version of Zeland. The simulated results show that the antenna can exhibit wideband characteristics. The impedance ...

However, there are many present day applications where even these small radiators are too large. A microstrip antenna incorporated with a single shorting pin is found to provide reduction in overall area...

INTRODUCTION Microstrip transceiver arrays have been demonstrated to provide higher efficiency on signal excitation/reception and low mutual coupling and have become a popular RF solution to parallel MR imaging at ultrahigh fields in humans [1,2]. In most designs, the ground planes of microstrips are separated (Fig 1) to minimize their mutual coupling [1-5]. Practically, due to space limitation...

Analysis of aperture-coupled microstrip antennas with a superstrate using space domain closed form Greens functions is presented. Integral equations are derived from applying the boundary conditions on the radiating patch, across the aperture, and on the microstrip feedline. The computation of space domain greens functions is performed using the closed-form. The solution of the integral equatio...
