Introduction to Filter
A filter is a network that provides perfect transmission for signal with frequencies in certain passband region and infinite attenuation in the stopband regions. Such ideal characteristics cannot be attained, and the goal of filter design is to approximate the ideal requirements to within an acceptable tolerance. Filters are used in all frequency ranges and are categorized into three main groups:
• Low-pass filter (LPF) that transmit all ....etc

Abstract”
Two major objectives are concerned in this paper. On one hand, a multiplicity of typical methodologies available for achieving dual-frequency operation for microstrip patch antennas are summarized and classified into three categories, based on their intrinsic mechanisms. On the other hand, by employing the dual-frequency solutions, microstrip patch antennas are applied to the mobile handsets of the third-generation IMT-2000 system. Two novel microstrip patch antennas with broadband property and miniaturized size have been prop ....etc

RECONFIGURABLE MICROSTRIP ANTEENA
Microstrip Antenna
 A microstrip patch antenna offers a low profile, i.e. thin, and easy manufacturability, which provides a great advantage over traditional antennas.
 The microstrip technique is a planar technique used to produce lines conveying signals and antennas coupling such lines and radiated waves.
 Microstrip array antennas, i.e., microstrip antennas having an array of microstrips, may be used with applications ....etc

History of Microstrip Patch Antenna
The rapid development of microstrip antenna technology began in the late 1970s. By the early 1980s basic microstrip antenna elements and arrays were fairly well established in terms of design and modeling, and workers were turning their attentions to improving antenna performance features (e.g. bandwid ....etc

Compact Microstrip Antenna¢ The microstrip antenna is a very thin metallic strip, placed a small fraction of a wavelength above a ground plane, separated by a dielectric.¢ Where size, weight, cost, performance, ease of installation, are of primary concern, microstrip antennas are the best solutions. Construction and Geometry ¢ 2.2 < ?r < 12. Low dielectric=>better efficiency, larger B/W.¢ A microstrip patch antenna is a radiating patch on one side of a dielectric substrate, which has a ground plane on the underside. The EM waves fri ....etc

Abstract
This paper present the design of an S-band circular microstrip patch antenna using a conventional coaxial probe feed technique. The antenna is designed to function within the frequency range of 2.0 GHz - 2.5 GHz, S-band. The antenna exhibited a return loss of -16dB and a directivity of 6.07dB. The microstrip patch antenna is designed on FR4 epoxy substrate and is to be feed with a 50 coaxial cable. The design of the antenna is done using MATLAB software and SonnetLite software for the electromagnetic simula ....etc
