Slot antennas are used typically at frequencies between 300 MHz and 24 GHz. The slot antenna is popular because they can be cut out of whatever surface they are to be mounted on, and have radiation patterns that are roughly omnidirectional (similar to a linear wire antenna, as we'll see). The polarization of the slot antenna is linear. The Basics of Patch Antennas, Updated - Orban Microwave The Basics of Patch Antennas, Updated By D. Orban and G.J.K. Moernaut, Orban Microwave Products ... A microstrip or patch antenna is a low-profile antenna that has a number of advantages ... Radiation Pattern A patch antenna radiates power in certain directions and we say that the antenna has Basic Antenna Theory - Wireless • Antenna radiation pattern (antenna pattern): • The power pattern and the field patterns are inter-related for plane wave: normalized field (power) values with respect to the maximum value. –Note: The power pattern and the amplitude field pattern are the same when computed and when plotted in dB. Slot Antenna

accordingly and results of microstrip patch antenna with FSS layer and microstrip patch antenna without substrate later compared on the basis of return loss, directivity, radiation pattern and gain. We used HFSS (high frequency structured simulator) software for simulation of antenna and to find out the results.
The Basics of Patch Antennas, Updated - Orban Microwave • 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 . • Change the phase of one of the signals by 90°. RADIATION PATTERN OF PATCH ANTENNA WITH SLITS The designed Microstrip patch antenna with four slits and a pair of truncated corners are. simulated using CADFEKO for finding the electric far field radiation, gain, directivity, radiation. pattern e.t.c. The electric far field of the Microstrip patch antenna is shown in figure.4.The gain of. the E-far field is 75 mv. Pattern Analysis of “The Rectangular Microstrip Patch Antenna” 43 | Page Figure 26: A general radiation pattern for a Microstrip antenna 2.6.3 Gain & Directivity The gain of the antenna is the quantity which describes the performance of the antenna or the capability to concentrate energy through a direction to give a better picture of the radiation performance.

What is radiation pattern in antenna? - Quora
A slot antenna consists of a metal surface, usually a flat plate, with one or more holes or slots cut out. When the plate is driven as an antenna by a driving frequency, the slot radiates electromagnetic waves in a way similar to a dipole antenna. The shape and size of the slot, as well as the driving frequency, determine the radiation pattern. Often the radio waves are provided by a waveguide, and the antenna consists of slots in the waveguide. Slot antennas are often used at UHF and ...
