Abstract:
A patch antenna is presented which has been designed to radiate frequencies in the range 4–9.5 GHz into human breast tissue. The antenna is shown by means of previously unpublished simulation and practical measurements to possess a wide input bandwidth, radiation patterns that remain largely consistent over the band of interest and a good front-to-back ratio. Consideration is also given to the antenna’s ability to radiate a pulse, and in this respect it is also found to be suitable for the proposed application.

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
