any 3d seismic survey can have an acquisition footprint. acquisition footprint is an expression of the surface geometry (most common on land data) that leaves an imprint on the stack of 3d seismic data. often we recognize it as amplitude and phase variations on time slices, which of course display the amplitudes within our data set at a specified two way time (cordsen, 2004). on the other hand,...

The radiation performance of a compact gap-coupled assembly of patches forming the geometry of elliptical patch antenna is simulated using glass epoxy FR4 substrate material. This assembly is achieved by cutting conventional elliptical patch antenna geometry into four independent patches through three narrow slits parallel to the minor axis of elliptical patch. So the elliptical patch is divide...

The triangular geometry of the microstrip patch is one of the most common shapes having a wide range of applications ranging from circuit elements to modern wireless antennas. Recent survey of open literature shows interesting development of this patch as novel circuit elements and antennas. In this paper, a very comprehensive review of the applications and investigations on triangular microstr...

Introduction The microstrip patch antennas are widely used in modern communication system due to low profile, low weight, low cost However, the antennas suffered from narrow bandwidth and low gain.[6 The major need for modern communication devices is to operate at wider band such as to support high speed internet, multimedia communication and similarly many more broadband services, this is achi...

Recently, several designs of single fed circularly polarized microstrip antennas have been studied. Relatively, a few designs for achieving circular polarization using triangular microstrip antenna are available. Typically existing design of single fed circularly polarized triangular microstrip antennas include the use of equilateral triangular patch with a slit or a horizontal slot on the patc...
