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 ... Effect of the Different Shapes: Aperture Coupled Microstrip ... Abstract: The paper reviews the effect of the different shapes on the aperture coupled microstrip slot antenna. Aperture coupled microstrip slot antenna couples the patch antenna with microstripline through an aperture. One effective way to increase the impedance band-width is to change the patch shape, feed shape and the slot shape. 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.
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.
In summary, a novel dual-polarized slot antenna with two coaxial feed lines was designed and fabricated. By using special slots in its circular patch radiator and short pins between the patch and the ground plane, the antenna realizes low cross-polarization of under -35 dB while also achieving high isolation of better than 36 dB. Design of U Slot Patch Antenna for Wi-max and Radar width of the longer slot are 0.3cm and 0.05cm respectively. The length and width of the shorter slot are 0.1 and 0.05 respectively. The diameter of the feed is 0.05cm and the hieght is 0.16cm.The proposed antenna has three resonant modes and having a maximum gain of 8.4 Dbi. Design of U Slot Patch Antenna for Wi-max and Radar Aperture coupled Wide-Band Micro Strip Antenna Design 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
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

Latest antennas released in Version 2019.2 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.
