A spectral-domain volume-integral-equation method is developed for analyzing superconducting planar transmission lines. This method rigorously accounts for the complex conductivity, the finite metallization thickness, and the anisotropy of superconductors. Calculated effective dielectric constants and quality factors for microstrip lines and coplanar waveguides show good agreement with measured...

Microstrip patch antennas that are multiband and downsized required to suit the high demand of modern wireless applications. To meet this need, a one-of-a-kind triple band array antenna has been proposed. The proposed 2x2 microstrip array, which comprises four hexagon-shaped radiating patches electromagnetically excited by centrally positioned feed line in same plane along with slotted ground p...

A new deep neural network (NN) approach applied to antenna array adaptive beamforming is presented in this article. recurrent NN (RNN) based on the gated unit (GRU) architecture used as a beamformer order produce proper complex weights for feeding of array. The proposed RNN utilizes four hidden GRU layers and one extra layer linear transformation. produced are subsequently compared with respect...

Printed antennas exemplified by the microstrip patch antenna offer an attractive solution to compact, conformal and low cost design of modem wireless communications equipment, RF sensors and radar systems. Recent applications have pushed the frequency well into the ram-wave region even in the commercial arena as evidenced by the worldwide race to develop advanced collision warning radar systems...

Articolul prezintă un studiu asupra unor tipuri de filtre trece-bandă (FTB) de microunde în tehnologie microstrip, cu o fantă de cuplaj practicată în planul de masă. Prezenţa unei fante poate conduce la un cuplaj electric mai strâns, sau la creşterea părţii electrice a cuplajului mixt, între cele două rezonatoare planare învecinate. Această structură cu defect de masă („defected ground structur...

The various perturbing structures for generation of circular polarization (CP) in a hexagonal shaped microstrip antenna (HMSA) with patch side length of 20 mm is used to resonate in the Mobile Satellite Service (MSS) band at a centre frequency of 2 GHz. The hexagonal geometry to achieve CP is perturbed in four different ways: first with a rectangular slot at centre, second with two narrow slits...

This paper presents the increase in bandwidth of a Microstrip Antenna using a simple slotted structure fed by Microstrip line. The main aim of proposed work is to obtain a large bandwidth antenna with reduced size. The proposed microstrip antenna has a wide bandwidth covering the range from 1.806-2.978 GHz. By using simple Microstrip Line feed wide bandwidth of 48.99% has been achieved. The pro...
