patches bandwidths up to 70% are reported(how ever only single patch design is attempted in this project). So the parametric study, design, fabrication and testing of a wi th wide band aperture coupled antenna has been attempted in this project. And an aperture coupled antenna with 500 MHz band width was designed at 2GHz What is the difference between slot antenna and patch ... Slot antennas are easier to make and modify, though patch antennas can be nearly as cheaply made using printed circuit board production lines. Slot antennas can send much more powerful signals. You can build a slot antenna into a structure and put it somewhere others may not know it is. The Pros and Cons of Slot Antennas A-SLOTTED RECTENGULAR MICROSTRIP PATCH ANTENNA - ijaiem.org reduced size wide band microstrip antenna; the design idea was taken from broadband antennas to make the antenna work in a large band of frequencies, rectangular patch antenna was chosen. There are many methods to reduce the size of the patch i.e. shorting wall, shorting pin, slot cutting etc. [4, 5]. The shorting microstrip antenna is a ...
tenna design. The antenna is designed on an FR4 sub- strate with the thickness of 1.6 mm and dielectric con- stant of 3.8. The antenna consists of a larger patch with a diamond slot, a smaller patch which serves as the feed- line and a partial ground plane. The patch antenna’s
EFFECTS OF SLOTS ON MICROSTRIP PATCH ANTENNA antenna. In this paper we have seen the effect of slot on microstrip patch antenna. By the use of slot we can enhance bandwidth, gain e.t.c.. Return loss is reduce. Axial ratio and radiation pattern is also improved. By the use of slot microstrip antenna can be used in many application. Application Note 3: Designing A Slot-Coupled Patch Antenna ... In this application note, we will show how to use EM.Picasso to design a 4 × 4 slot-coupled patch antenna array with a microstrip corporate feed network. The design process involves three steps: design of the slot-couple patch element, design of the power divider, and finally, construction of the 16-element array.

Design, Implementation and Experimental Comparison between ... Fig. 9. Constructed dual port,dual polarized slot coupled patch antenna The simulated and measured S11,S22 and S12 results for proposed and implemented dual polarized slot coupled antenna are shown in Fig.10.The quarter wave microstrip fed (port 1) has 50MHz and slot coupled port (port2) has 100MHz input 10dB bandwidth. Broadband Capacitive Coupled Microstrip Antenna with I-shape ... In this communication, I-shape slot loaded capacitive coupled patch antenna with broad band behaviourhas been presented. The impedance bandwidth of 58% has been achieved. This antenna can be used for wireless communication system. The proposed antenna also operates in 5GHz band hence can be used for WLAN application. Proximity Coupled Equilateral Triangular Microstrip Antenna ... In this paper a design of proximity coupled equilateral triangular microstrip antenna with diamond shape slot on the radiating patch is studied. The antenna consists of two layers with glass epoxy material of thickness (h) 0.32cm each forming total thickness of 0.64cm.
The GUI of the Slot-Coupled Microstrip Patch Antenna Array Synthesizer app. After the analysis, the app reports whether the single antenna design parameters are optimal by using the computed S-parameter (S11) value compared to the pass/fail target criterion that the app user specifies before running the simulation.

Index Terms-- Aperture-coupling, slot, microstrip patch antenna, broad band matching. I. INTRODUCTION.
In an antenna structure having a plurality of serially fed patch elements, at least one of the patch elements has a slot coupling to the continuation of the feed line for influencing the radiation of this patch element. US6642898B2 - Fractal cross slot antenna - Google Patents A fractal cross slot broad band antenna comprises a five layer configuration including a radiating fractal cross slot layer having a plurality of antennas each comprising a plurality of radiating arms. Locker 2 | Antenna (Radio) | Coaxial Cable Since they have a significant influence on the slot impedance and res- onance behavior of the antenna, only a careful aperture design in conjunction with the via positions and the reflector distance leads to suitable impedance matching.
