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.

Variation of E-shaped Microstrip antenna, a broadband rectangular Microstrip antenna cut with three unequal length rectangular slots is proposed. A detail analysis to study the effects of rectangular slots that realizes broader bandwidth is presented. Analysis of slot-loaded rectangular microstrip patch antenna 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. 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 Analysis of slot-loaded rectangular microstrip patch antenna
effect of slots on performance of the microstrip patch antenna
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 ... Effect of Open Stub Slots for Enhancing the Bandwidth of ... Effect of Open Stub Slots for Enhancing the Bandwidth of Rectangular Microstrip Antenna 225 bandwidth of 24.62% when compared to BW6. Hence the use of closed slot at the centre of TSRMA is more useful in enhancing the secondary band i.e. BW8 of antenna. Since the separation between BW7 and BW8 is quite large
