چکیده
This paper presents a novel way for achieving endfire radiation pattern using microstrip patch antenna array. The extensively used microstrip patch antennas i.e. rectangular and circular microstrip patch antennas, either single patch or in an array configuration do not have an endfire radiation pattern. The antenna array presented in this paper is designed by changing the geometry of the antenna and current distribution. Array consists of U-shaped radiating elements which alter the radiation pattern of individual radiating element and a partial ground plane is used to change the current distribution. In start, the paper presents the parametric study of novel single U-shaped antenna and afterwards a complete analysis of current distribution for two element, four element and eight element U-shaped microstrip antenna arrays is given.

متن کاملA Capacitive Fed Microstrip Patch Antenna with Air Gap for Wideband Applications (RESEARCH NOTE)
In this paper a microstrip antenna on a suspended substrate with capacitive feed is presented. capacitive feed is created by a slot within the rectangular patch around the feed point. The proposed antenna exhibits a much higher impedance bandwidth of about 47% (S11 < −10 dB). Effects of key design parameters such as the air gap between the substrate and the ground plane, the gap width between r...

Analysis of aperture-coupled microstrip antennas with a superstrate using space domain closed form Green's 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 green's functions is performed using the closed-form. The solution of the integral equat...
متن کاملReduction of Mutual Coupling between Patch Elements Using Split-ring Dgs
A defected structure etched in the metallic ground plane effectively disturbs the shield current distribution in the ground plane and thus, DGS potentially obtains wide reject-band, which meet the emerging application challenges. Microstrip patch antenna arrays are very popular for today’s wireless communication system. In this paper a new scheme is proposed to reduce the mutual coupling betwee...
متن کاملA compact stacked Quasi-fractal microstrip antenna for RFID applications
In this paper, we propose a new compact quasi-fractal shaped microstrip antenna that consists of a hexagonal patch as the main radiator and a complementary stacked patch as the parasitic element. The overall surface of the proposed quasi-fractal patch is about 55% lower than the conventional hexagonal patch. Using of stacked technique, the gain reduction of compression technique is almost compe...
