Abstract: The design of a stacked aperture coupled microstrip patch antenna is very challenging when dealing with wide-band impedance matching. Impedance matching is a major challenge because the effect of changing one of the parameters in not independent of the others. When this is the case the role of a computer aided design package is vital. U-SLOT STACKED PATCH ANTENNA USING HIGH AND LOW DIELECTRIC ...

A Broadband Proximity-Coupled Cavity-Backed Microstrip ... A broadband stacked microstrip antenna with cavity-backed ground plat is presented in this paper, where the proximity-coupling feeding mechanism is employed. Also, there is a slot on the surface of... Dual-polarized slot-coupled planar antenna with wide ... slot-coupled antenna with a better isolation can be obtained by using multiple coupling slots, as the multifeed technique is ca-pable of suppressing higher-order modes. One such an antenna is reported by Brachat et al. in [15], where a dual-polarized slot-coupled stacked-patch antenna with multiple slots is pre-sented. APLab Research - UMass Amherst
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].
Printed Wide Slot Ultra-Wideband Antenna - InTech - Open slot antenna has limited bandwidth, whereas wide-slot antennas exhibit wider bandwidth. Recently, different printed wide-slot antennas fed by a microstrip line or coplanar wave‐ guide have been reported [7, 8]. Apart from these antennas, monopole like slot antennas have also been reported to have wide bandwidth characteristics [9-11]. Capacitive Coupled Truncated Corner Microstrip Stack Patch ... Abstract. A design of a circular polarized microstrip stack patch antenna is presented. In this paper, a corner truncation at opposite side of square patch is printed on two FR-4 substrates, one is for stack and another for radiating patch, to achieve circular polarization; the rectangular slot is introduced at the centre in diagonal with axis to increase bandwidth and reduce size.
Abstract An aperture-coupled microstrip stacked patch antenna is studied with the goal of obtaining wide bandwidth, low cross-polarization, and weak parasitic radiation from the feeding aperture for applications in printed phased array antennas.
