U-slot rectangular patch antennas 13,14 —as well as U-shaped parasitic patch antennas 15 with thick foam or substrate—have been found to provide wide bandwidths without enlarging antenna size. In addition, the use of shorting pins or shorting walls on the unequal arms of a U-shaped patch or L-probe feed antennas 16,17 have helped achieve ... Mutual Coupling Reduction between Closely Spaced U-slot Patch ... The U-slot patch antenna is versatile antennas that because of its features like wide bandwidth, multi-band resonance and the ease of achieving different polarizations. This research first investigated the u-slot patch antenna, its features and capabilities. Second a CAD optimization to Microstrip antenna - Wikipedia The half-wave rectangular microstrip antenna has a virtual shorting plane along its center. This may be replaced with a physical shorting plane to create a quarter-wavelength microstrip antenna. 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. Improving bandwidth rectangular patch antenna using different ...

Slots in patch antenna. U-Slot Microstrip Patch Antenna for Wireless Application | Open Access Journals
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. Effect of Capacitive loading on slot loaded Dual Band ... location of the slots with respect to the patch is defined by the quantities w and l which are very small with respect to the dimensions L and W of the patch. The antenna may be fed with either an aperture or a probe feed [1]. Fig 3 top & side view of designed antenna with parallel slots Authors have c probe feeding. On the Use of Slots in the Design of Patch Antennas The methods developed for efficient wideband patch 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 ... The U-slot patch (Huynh and Lee, ...
Effect of Feed Position for Same E-Type Microstrip Patch ...
A patch antenna is literally a patch of metal or other conductor on a flat surface. There may or may not be a ground plane on the other side of the substrate. The directionality, gain, polarization, and impedance are a function of the size and shape, and placement of the feed line. Most GPSs use a patch antenna.

Effect of Feed Position for Same E-Type Microstrip Patch ... slots in the patch which makes an E shape in the patch. E-shaped patch antenna can increases bandwidth above 30% compared to a regular rectangular patch antenna. Comparing both designs, the E-shaped is much simpler to construct by only adjusting length, width and position of slots.[9] Firstly we consider a rectangular patch antenna, than for ... Effect of Height on Edge Tapered Rectangular Patch Antenna ... (a) Simple patch antenna For simple patch effects of height of substrate h=1.57 , 1.59,1.6,2 mm has been shown below it has been found that the height of the substrate is increases their return loss also increases.

(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
For that, a rectangular patch antenna with 16×18×1.6 mm3 dimensions with dual-band characteristics, was designed, fabricated and characterized.
