SHIVNARA YAN et al.: SLOT- LOADED RECTANGULAR MICROSTRIP PATCH ANTENNA 425 the present work, the patch is fed by co-axial cable (50 ohm). Since the slot is thin, the voltage can be sinusoidal with zero voltage across the ends of slot. A rectangular slot antenna with improved bandwidth A rectangular microstrip slot antenna fed by a microstrip line, which achieves a very large bandwidth on a relatively thin substrate, is presented. The performance is achieved by employing a combination of a rectangular slot in the ground plane, and the use of the microstrip line perpendicular to the rectangular slot. What is the difference between slot antenna and patch Jan 25, 2016 · A slot antenna is literally a hole within a plane, whereas a patch antenna is a separate medium on top of a plane. Slots can be used in low frequency apps, but patches work best at UHF and above. 4.8k views · View 6 Upvoters Enhancing the Bandwidth of a Microstrip Patch Antenna Enhancing the Bandwidth of a Microstrip Patch Antenna using Slots Shaped Patch Atser A.

For example, an insulated slot in a patch, the addition of different slot shapes at the radiating element, such as the L-shaped slot, a T-shaped slot, an H-shaped slot and the fractals slot have also been reported for large bands [5]-[9]. Among these techniques, a U-shaped slot will be used on the patch of the coaxially fed square patch antenna.
bandwidth of the designed U-slot microstrip patch antenna is enhanced by adjusting the U-slot dimensions and adding two shorting walls. Two modified designs are proposed to achieve a wide bandwidth operating in wideband communications. The first modified design is by increasing the U-slot Design & Simulation of Double U-Slot Microstrip Patch ... tively. The U- slot patch antenna is designed for increasing the bandwidth and return loss but gain cannot increase. If array of the U- slot patch antenna is used then the gain can be im-proved. Therefore, the antenna will be better work in the Wi-MAX applications and wireless communication s system. HFSS tutorial 2-Microstrip Patch Antenna with a cutting ...
