To excite circular polarization in a patch we need to do three things: • Split the signal in two equal parts. • Feed one signal to the horizontal radiator (x axis) and the other to the vertical radiator (y axis). Each radiator behaves like a pair of radiating slots in the patch antenna as shown in Figure 5 .
modifying the formulas for reactively loaded patch with slot loading. Broadband antennas provide higher bandwidth at the expense of their high thickness. Dual band microstrip antenna with capacitive loading can be an alternative to large bandwidth antennas, especially when a large bandwidth is required for Microstrip Patch Antennas - EM Lab Microstrip Patch Antennas Slide 19 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. 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 miniaturization by slots loading - IEEE ...
microstrip-antenna IEEE PAPER 2017 - engineering research papers
A dual-frequency compact microstrip patch antenna use the rectangular microstrip patch loaded with one shorting pin. Other dual-frequency antennas with square slot or rectangular slot loading are reported by Chen [1998] and Gaa and Li [1999a]. To satisfy specific requirements of various practical applica- tions, more research results on the dual-frequency microstrip antennas are still required. ENHANCEMENT OF BANDWIDTH AND GAIN OF A RECTANGULAR MICROSTRIP ... In this project, method of moments based IE3D software is used to design a Microstrip Patch Antenna with enhanced gain. The aim of the project is to design a rectangular Microstrip Patch Antenna with enhanced gain and bandwidth and study the effect of antenna dimensions Length (L), Width (W) and substrate parameters relative Dielectric constant ...
