This paper presents the design and simulation of a compact rectangular slot patch antenna for dual frequency operation at 2.4 GHz and 5.2 GHz using the inset feed technique. The simulation of the designed antenna was done with the aid of computer simulation technology (CST) microwave studio version 12. Design of Narrow Slotted Rectangular Microstrip Antenna VSWR of the proposed antenna that is Owing to it objective is to design a reduced 1:1.03 at the resonant frequency 8.73 GHz. size wide band microstrip antenna; the Good broadside radiation pattern obtain in design idea was taken from broadband fig. 5. antennas to make the antenna work in a large band of frequencies of the many CONCLUSIONS ...

The end result is that the resonant antenna will efficiently feed a signal into the transmission line only when the source signal's frequency is close to that of the design frequency of the antenna, or one of the resonant multiples. This makes resonant antenna designs inherently narrowband, useful for a small range of frequencies.
Design A Dual-Frequency Rectangular Patch Antenna ... The design graphs are then used to compute the dimensions of a rectangular patch and feed network for a dual-frequency antenna for use at 1.9 and 2.4 GHz. For the feed network, two transmission lines are used to connect the two edge feeds to an open circuit stub to match the antenna at the two frequencies. Design of asymmetric slot antenna with meandered narrow ...

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.
A single narrow slot radiator can also work on frequencies ±5 … ±10% besides its resonance frequency. For array antennas, this is not possible so easily. Such a group antenna is fixed strongly to a single frequency, which is determined by the spacing of exactly λ g , and for which the antenna has been optimized.

ground plane [8]. However, several narrow bandwidth systems have been used for a long time, such as WLAN (5-6GHz) and X-band (7.7-8.5GHz). Therefore, plenty of UWB antennas with band notch antennas have been proposed for reducing the potential interference between UWB and narrow band A Compact Wide slot antenna with dual band-
