effect of the superstrate used on the patch antenna to provide protection from heat and environmental hazards etc., results in change of important parameters like impedance, bandwidth (frequency range for SWR ≤ 2), gain, resonant frequency etc. This geometry of microstrip patch with dielectric superstrate can form part of a specific
In the present paper, the analysis of a slot-loaded rectangular microstrip patch antenna using equivalent circuit concept is presented. The slot is taken as a capacitive reactance on the patch. Design And Analysis Of Compact U Slot Microstrip Patch ... Design And Analysis Of Compact U Slot Microstrip Patch Antenna 9 Figure 1: U -Slot loaded rectangular micro strip antenna These properties make FR4_epoxy very attractive to be used as substrates for the Effect of Height on Edge Tapered Rectangular Patch Antenna ... antenna obtained maximum gain of 9.55dB having VSWR is less than 2. Keywords- Microstrip patch antenna, Parasitic stubs, Slot antenna, wideband I. INTRODUCTION The idea of microstrip patch antenna was introduced in 1950’s but it become popular and used in various applications in 1970’s. Microstrip patch antenna are Study of the Dielectric Superstrate Thickness Effects on ... effect of the superstrate used on the patch antenna to provide protection from heat and environmental hazards etc., results in change of important parameters like impedance, bandwidth (frequency range for SWR ≤ 2), gain, resonant frequency etc. This geometry of microstrip patch with dielectric superstrate can form part of a specific
An inverted-F antenna is a type of antenna used in wireless communication. It consists of a monopole antenna running parallel to a ground plane and grounded at one end.
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 ( … Effects of Square- and Rectangular-Shaped Slots Kept Over Jan 26, 2018 · Abstract. This paper clearly explains the slot loading effects of microstrip antenna. The effect of a series of square-shaped slots of different sizes is studied by using parametric analysis, and radiation characteristics are observed. Slot dimensions and position are chosen to get the better results. 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.
