antenna is from 2.69 to 10.24 GHz, I. INTRODUCTION Microstrip antennas can be divided into two basic types by structure, namely microstrip patch antenna and microstrip slot antenna. The slot antennas can be fed by microstrip line, slot line and CPW. In this paper, we presented the design of slot antenna fed by microstrip line. The designed Tiny Microstrip Antenna Covers WLAN, LTE, and WiMAX ... In this case, adding the U-shaped slot in the patch enhances bandwidth by 33.52%. In ref. 29, a broadband high-gain microstrip patch antenna with a slot was proposed. A dual-band characteristic was obtained by using a double U-slot in the patch. The antenna has a 37% impedance bandwidth. Slot Antenna - an overview | ScienceDirect Topics The slot antenna, consisting of a narrow slit in a ground plane, is a very versatile antenna. With modification, it is amenable to waveguide, coplanar waveguide (CPW), coaxial, slot line, or microstrip feeding schemes and has been used in all aspects of wireless and radar applications. What is the difference between slot antenna and patch ...
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.
respectively. By using the strip and slot, the proposed antenna deals properly with frequency shift for real application when embedded inside a handheld reader. V. CONCLUSION Thus the slot microstrip antenna was designed.The antenna shows good performance at 2.4GHz. Antenna gain, directivity, efficiency and return loss are measured. Effect of slots on microstrip patch antenna characteristics In this paper, a novel design approach of microstrip patch antenna is presented. The antenna consists of slotted conducting patch element with air filled dielectric medium. The antenna is single-feed type and wideband. The proposed design has a reduced antenna size with high gain, low VSWR and good radiation pattern. The proposed antenna is suitable for various modern wireless communication ... Asymmetrical π-Shaped Slot Embedded Microstrip Antenna for ... Abstract. A unique geometry of a square patch antenna with an embedded asymmetrical π-shaped slot for circular polarization is presented. The proposed structure has an aperture coupled feed which is matched over a very wide frequency band. Microstrip Antennas – Part 2 - McMaster University

The antenna has 9.37 dB gain at 8.1 GHz and input match of antenna −17.5 dB. Effect of Slots in Ground Plane and Patch on Microstrip PDF | This paper presents the effect of the slots in ground plane and patch on resonant frequency, impedance bandwidth, gain and side lobe. The microstrip antennas have been designed on ε r = 4.3 Microstrip Patch Antennas - University of Texas at El Paso The transmission-line model represents the microstrip antenna by two slots, separated by a low-impedance transmission line of length L. Looking at a cross section of the antenna (x-y plane), this is effectively a non-homogeneous transmission line. Fringing effects make the microstrip line look wider than it is. Effective dielectric
Slots are basically used for Bandwidth enhancement and for compactness of antenna. The antenna is designed at some particular resonating frequency which gives some bandwidth then addition of slot overlaps the fundamental mode of antenna and creates higher order mode which overlaps the original bandwidth which gradually increases the overall bandwidth of the antenna. What is the difference between slot antenna and patch ... A slot antenna is a slot in a flat piece of metal or other conductor. It can be thought of as sort of the complementary version of a dipole. Rather than a 1/2 wavelength of centerfed wire in free space making up a dipole antenna, a dipole slot antenna is usually a 1/2 wavelength long slot in a large ground plane. It can be fed in a number of ways. Microstrip antenna - Wikipedia Specifications. The radiation from a rectangular microstrip antenna may be understood as a pair of equivalent slots. These slots act as an array and have the highest directivity when the antenna has an air dielectric and decreases as the antenna is loaded by material with increasing relative dielectric constant.
