Design of a high isolation dual‐polarized slot‐coupled The design of a wideband dual‐polarized slot‐coupled stacked microstrip antenna with high isolation is introduced. The proposed stacked‐patch antenna is excited by both open‐ended and T‐shaped microstrip lines via two H‐shaped slots placed orthogonally so as to improve the isolation between the two polarization ports.

Size, weight, feed fabrication, and high coupling between stacked patches are the main disadvantages of the stacked antennas [21].Joshi and.Chen and Zhang [23] described Bandwidth enhancement of a microstrip-linefed printed wide-slot antenna with a fractal shaped slot.
Using stacked slot coupled printed antennas resolve the conflict between enhanced bandwidth and back radiation. Using coplanar patch antenna in addition to stacked coupled layers gives more improvement in terms of low radiation loss and less dispersion. A personal overview of the | 9.

Wideband Aperture Coupled Patch Array Antennas — … antennas [1,2] are excellent candidates for low profileapplications. For wideband performanceE-shaped and U-shaped slots on microstrip patches have been proposed [3–8]. Stacked patch antennas have also been proposed for moderately wide bandwidth where two patches are coupled to each other to obtain a contiguous dual-band performance [9,10].

To produce the antenna, a symmetrical slot patch radiator is printed on a 1-mm-thick FR-4 printed-circuit-board (PCB) substrate with relative permittivity of 4.65. The circle patch and the ground plane have diameters of 60 and 120 mm, respectively. Aperture Coupled Microstrip Antenna Design and Analysis Aperture Coupled Microstrip Antenna Design and Analysis Michael Paul Civerolo A linearly-polarized aperture coupled patch antenna design is characterized and optimized using HFSS antenna simulation software [1]. This thesis focuses on the aperture coupled patch antenna due to the lack of fabrication and tuning documentation An Introduction of Aperture Coupled Microstrip Slot Antenna The first aperture coupled microstrip antenna was introduced in 1985 by D M Pozar (4) Figure1: Aperture coupled microstrip slot antenna The geometry of an aperture coupled microstrip antenna is shown in Fig. 1. It consists of two substrates bonded together, with a ground plane in between (5).The radiating patch is printed on the top (antenna ...
