Feb 13, 2014 · This paper presents a printed wide-slot antenna design and prototyping on available low-cost polymer resin composite material fed by a microstrip line with a rotated square slot for bandwidth enhancement and defected ground structure for gain enhancement. An I-shaped microstrip line is used to excite the square slot. A Bandwidth Improved Circular Polarized Slot Antenna Using A circular polarized (CP) slot antenna is designed with a slot composed of multiple circular sectors (MCS). The design has advantages of having a wide 3 dB axial ratio (AR) bandwidth of 57.4%, achieving a good AR smaller than 2 dB in most areas of the frequency range. The design of the antenna follows a multi-objective optimization procedure that applies computational power rather than human Design of a novel bandwidth-enhanced double-slot TSA and The paper proposed a double-slot Vivaldi antenna, the impedance bandwidth has been significantly improved, the fractional bandwidth of the antenna reached 142%. But the bandwidth of the gain more than 10 dB is only from 5 GHz to 15 GHz. In this paper, a modified tapered slot antenna with double-slot structure, is proposed. Planar amplifier array with improved bandwidth using Planar Amplifier Array With Improved Bandwidth Using Folded-Slots H. s. Tsai, M. J. W. Rodwell, Member, IEEE, and R. A. York, IEEE Abs-t- Active antennas on semiconductor substrates often suffer limited bandwidth. We report on a relatively broadband quasi-optical amplifier cell and 4x4 array using folded-slot anten-
This technology demands for antennas with wide bandwidth and good isolation characteristics. There are various techniques proposed for improving the bandwidth of microstrip antennas. In [1], authors achieved considerable amount of bandwidth by employing slots and annular ring in the ground plane.
