Orban and G.J.K. Moernaut, ... already “large” ground plane has very little effect on gain. In the antenna in Figure 1, ... (length in the y-axis) of the patch and the width of these slots equals the substrate height. These slots typically have a directivity of 2 to 3 dB compared Broadband Slot Cut Rectangular Microstrip Antenna ... The realized bandwidth in the proposed configuration is more than the bandwidth obtained in equivalent rectangular patch antenna with U-slot or pair of rectangular slot i.e. E-shaped patch antenna. The proposed configuration gives broadside radiation pattern over the bandwidth with a peak broadside gain of more than 8 dBi. Microstrip Patch Antennas - University of Texas at El Paso

Design & Simulation of Double U-Slot Microstrip Patch Antenna ... Design & Simulation of Double U-Slot Microstrip. Patch Antenna for WiMAX Application. Md. Suaibur Rahman 1, Md. Munjure Mowla 2, Md. Mahabub Alam 3. Abstract — This paper presents the numerical simulation of double U-slots microstrip patch antenna for W iMAX application. The proposed antenna is feed by the Transmission line. EFFECTS OF SLOTS ON MICROSTRIP PATCH ANTENNA This paper presents effect of slots on microstrip patch antenna and its parameters. The effect is shown on bandwidth, gain, radiation pattern, return loss, axial ratio and size of an antenna. The slots on the patch or on the ground plane will help to design a antenna with improved bandwidth and effeciency. (PDF) Effects of Slot Loading on Microstrip Patch Antennas The slots of those antennas are loaded in symmetrical with respect to the edge of the patch. However, notch antenna is a form of slot antenna constituted by asymmetrical notching one side of the ...
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 .
Broadband Slot Cut Rectangular Microstrip Antenna ... The realized bandwidth in the proposed configuration is more than the bandwidth obtained in equivalent rectangular patch antenna with U-slot or pair of rectangular slot i.e. E-shaped patch antenna. The proposed configuration gives broadside radiation pattern over the bandwidth with a peak broadside gain of more than 8 dBi. Microstrip Patch Antennas - University of Texas at El Paso 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. A Study on the Effect of a Rectangular Slot on ... In this paper, a study on the effect of rectangular slot in a non-radiating edge of rectangular microstrip patch antenna on the miniaturization of the antenna has been presented. It has been investigated from parametric studies that frequency becomes lower due to the increase of effective electrical path length along the slot dimensions. Using Hilbert Curve Slot for Bandwidth Enhancement of ...
How can I study the slots effects on patch antenna performance? ... By seeing its current distribution you can analyse the effect of slots. Position and size of slots affect antenna performances ...
Microstrip antenna - Wikipedia In telecommunication, a microstrip antenna usually means an antenna fabriciated using .... This is sometimes called a half-patch. The antenna only has a single radiation edge (equivalent slot) which lowers the directivity/gain of the antenna. Novel Design of Microstrip Antenna with Improved Bandwidth - Hindawi Sep 24, 2014 ...
