Effect of slots on microstrip antenna

antenna design are based on one or more of the following principles: A. Thick substrates of low permittivity are used. B. A scheme is devised to reduce the mismatch problem associated with thick substrates. C. By means of parasitic elements or slots, either new resonances are introduced close to the main resonance or existing Frequency tuning and miniaturization of square microstrip ...

Choudhury, Effect of rectangular ground slot in a microstrip line fed monopole UWB antenna for multiband applications, Microwave and Optical Technology Letters, 56, 8, (1891-1895), (2014).

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. 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.

Performance Enhancement of Pentagonal Patch Microstrip-FED The analysis is performed and results are obtained using Ansoft HFSS. Various parameters which include impedance bandwidth, gain, efficiency, radiation pattern, current distribution of the antenna are studied. Inset Fed Microstrip Patch Antenna – MicrowaveTools

Effect of Feed Position for Same E-Type 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 ... 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 Slot #2 Slot #1 L y z x. The TL model is not accurate and lacks versatility. However, it gives a relatively good physical insight into the nature of the patch antennaand the field distribution for all TM 00 n modes. The slots represent very high-impedance terminations on both sides of the transmission line ( almost an open circuit).
