Microstrip fed slot antenna array

Abstract: A novel concept of a feeding network of a microstrip antenna array composed of series-fed linear subarrays has been shown. The proposed feeding network utilizes a concept of a slot coupler, in which two microstrip lines are coupled through a slot in a common ground plane.

Slot Antenna - an overview | ScienceDirect Topics The slot antenna, consisting of a narrow slit in a ground plane, is a very versatile antenna. With modification, it is amenable to waveguide, coplanar waveguide (CPW), coaxial, slot line, or microstrip feeding schemes and has been used in all aspects of wireless and radar applications. Microstrip antenna - Wikipedia The most common type of microstrip antenna is the patch antenna.Antennas using patches as constitutive elements in an array are also possible. A patch antenna is a narrowband, wide-beam antenna fabricated by etching the antenna element pattern in metal trace bonded to an insulating dielectric substrate, such as a printed circuit board, with a continuous metal layer bonded to the opposite side ...

They include: bi-directional slot antenna fed by a microstrip line, circularly polarized T- slot antenna, cavity-backed microstrip-fed slot antennas and arraysVarious single elements and arrays have been designed at different frequency bands (900MHz, 1.8GHz, 2.45GHz, 5.8GHz, 10GHz, and 24GHz). A Compact Broadband Stripline-fed Slot Antenna for Array… INTRODUCTION Striplinefed slot antennas or microstnp-fed cavity backed antennas have been subjects of n umerous investigations in recent years.Several methods have been proposed to increase the bandwidth of microstrip-fed slot or CBS antennas, such as series radius stub 111... Dual Linearly Polarized Microstrip Array Antenna |… The aperture coupled microstrip antenna was developed by using cross slot aperture at the plane between feed line plane and ground plane.Most of the dual polarized microstrip antenna was design to generate signals with vertical and horizontal polarized or +45 and -45 polarized. Broadband and high gain waveguide-fed slot antenna array

The design of 4×4 microstrip-fed slot antenna array has been presented in this paper along with its applicability in microwave image reconstruction of concrete structure defects. The measurement results show that the each microstrip slot antenna element in the array produces return loss good enough to be implemented in the microwave imaging.
