microstrip line fed, proximity coupled and slot coupled microstrip patch antennas are provided. Numerical results in the form of current distributions and input impedance are presented and compared with the results given in literature. A microstrip antenna idea was firstly introduced in 1950’s but it became popular and Wideband Aperture Coupled Patch Array Antennas — High Gain ... 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]. PPT – Microstrip Antennas PowerPoint presentation | free to ... A coaxially-fed aperture-coupled stacked patch antenna. 6 ... Lens-coupled printed antennas have several ... Effect of Slot Dimensions on Antenna Design ... Slot Antenna Uses Dual Polarization | Microwaves & Radio ... 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.

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.
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.

aperture-coupled stacked-patch antenna with two off-set slots. In that way, the dielectric layers 1 – 4 (Fig. 1) were replaced by dielectric posts. Using this approach, a broadband dual-polarized stacked-patch antenna with a –10 dB bandwidth of 28.7 % was developed and introduced in [3].
