Antenna Array 1. The effect of ground location on the microstrip slot antenna Since PIN diodes would be surface-mounted directly on the dielectric material, bias lines and therefore DC ground is inevitable. To investigate the effect of this ground location on the microstrip slot antenna function, ANALYSIS OF SLOT COUPLED MICROSTRIP PATCH ANTENNAS A THESIS ... eliminate the effect of temperature on the resonance frequency of a microstrip antenna if a proper material is selected, [1]. Different feeding techniques of microstrip patch antennas are shown in Figure 1.1. Microstrip line and coaxial probe feed methods, shown in Figure 1.1.a and Figure An Introduction of Aperture Coupled Microstrip Slot Antenna An aperture-coupled design is proposed for Microstrip slot antenna to improve its radiation pattern as well as bandwidth. It is based on coupling of an aperture between the patch antenna and Microstrip slot line. The first aperture coupled microstrip antenna was introduced in 1985 by D M Pozar (4) Figure1: Aperture coupled microstrip slot antenna Antenna Theory Slot - Tutorials Point

Before one explains what the question asks, for let us compare the solitary dipole antenna with the slot antenna, each of the same length. One may look at the dipole as a length of conductive material equal to half a wavelength, placed and surrounded by a large sheet of insulating space, if one considers one plane in which the dipole is placed. How does a slot effect an antenna’s bandwidth? - Quora Slots are basically used for Bandwidth enhancement and for compactness of antenna. The antenna is designed at some particular resonating frequency which gives some bandwidth then addition of slot overlaps the fundamental mode of antenna and create... An improved broadband E patch microstrip antenna for wireless ... et al. [1997] investigated probe-fed microstrip antennas with U slots and achieved bandwidths of 18% and 30%, respectively. A circular microstrip antenna with an embedded reactive loading is presented by Wong and Jan [1998], whereas a flower-shaped microstrip antenna patch, semicircle fed, is reported by Ooi and Ang [2005].
