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.
the two slots in-phase with nearly equal antenna currents. Thus, the patch operates as an array of two slots with a free-space separation somewhat less than λ/2. Maximum radiation is normal to the plane of the patch. Polarization is at right angles to the length of the slots, par-allel to the feedline orientation shown in Fig. 1. A Review- Microstrip Patch Antenna Design number of iterations, size of antenna decreases. By providing a number of slots over the patch, bandwidth is improved of patch antenna. Due to presence of multiple slots, Q factor decreases and value of patch inductance increases. By the decrease in Q factor, the bandwidth (BW) of patch antenna is increased accordingly, Bandwidth, BW [9] = 1 √2 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 ...
The antenna's final performance depends not only on the structure of the radiating element, but also on the antenna's location within the laptop, and on other nearby components.

(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 ... How can I study the slots effects on patch antenna performance?

The J-pole antenna, more properly known as the J antenna, [1] was first invented by Hans Beggerow in 1909 for use in Zeppelin airships. [2] Trailed behind the airship, it consisted of a single element, one half wavelength long radiator with … www.ejaet.org ISSN 2394-658X (Ejaet) The effect of slot angle on the resonant frequency, band width and return loss of the antenna is shown in fig.3. Increasing the slot angle increases the resonant frequency as the overall resonating length is decreased. Open Journal Systems
