The operating frequency of array is from 12 to 18 GHz. The antenna array has been designed and simulated on FR4 Substrate with dielectric constant of 4.4. This paper presents that, the detail steps of designing and simulating the rectangular patch antenna and rectangular patch antenna Array in Ku-band. Patch Antenna or Microstrip Antenna. A patch antenna or microstrip antenna is a narrowband, wide-beam antenna. It is also-called printed antenna. It has two dimensional physical geometry. The simplest patch antenna uses a patch which is one-half wavelength long, so that the metal surface acts as a resonator similarly to the half-wave dipole.
Microstrip Patch Antenna calculator | Patch Antenna Formula
This Microstrip Patch Antenna calculator calculates patch length and width.This patch antenna calculator uses microstrip dielectric, height and frequency for calculation.
Microstrip line is most popular for antenna designs due to due to its Smaller size, Ease in fabrication andeasier troubleshooting. Hence microstrip patch antenna found its place in mobile phones and other rf circuit designsrequiring constained antenna devices.The patch antenna calculator calculates length and width as outputs and requires inputs such as RFcenter frequency, dielectric constant and height of substrate.

A patch antenna is a type of antenna with a low profile, which can be mounted on a surface. It consists of a planar rectangular, circular, triangular, or any geometrical sheet or 'patch' of metal, mounted over a larger sheet of metal called a ground plane. They are the original type of microstrip antenna described by Howell in 1972;[1] the two metal sheets together form a resonant piece of microstriptransmission line with a length of approximately one-half wavelength of the radio waves. The radiation mechanism arises from fringing fields along the radiating edges.[2] The radiation at the edges causes the antenna to act slightly larger electrically than its physical dimensions, so in order for the antenna to be resonant, a length of microstrip transmission line slightly shorter than one-half the wavelength at the frequency is used. The patch antenna is mainly practical at microwave frequencies, at which wavelengths are short enough that the patches are conveniently small. It is widely used in portable wireless devices because of the ease of fabricating it on printed circuit boards. Multiple patch antennas on the same substrate (see image) called microstrip antennas, can be used to make high gainarray antennas, and phased arrays in which the beam can be electronically steered.
A variant of the patch antenna commonly used in mobile phones is the shorted patch antenna, or planar inverted-F antenna (PIFA). In this antenna, one corner of the patch (or sometimes one edge) is grounded with a ground pin. This variant has better matching than the standard patch.Another variant of patch antenna with the partially etched ground plane, also known as printed monopole antenna, is a very versatile antenna for dual-band operations.[3]
