Antenna Performance

This research article gives a detailed insight of the design, simulation of a compact circular shaped microstrip patch antenna that is fed using a coplanar waveguide feed (CPW for practical wireless communication applications). The antenna is typically designed for Ultra wideband (1.46-6GHz), Bluetooth (2.4GHz), ZIGBEE (2.4GHz), WLAN (5.15- 5.35 GHz and 5.725- 5.825), Wi-Fi (2.4-2.485GHz) and HIPERLAN-2(5.15 - 5.35 GHz and 5.470 -5.725GHz) wireless applications with stop band characteristics for the H (partial C band). The proposed antenna has an overall packaged structure dimensions of 78 x75 x1.605 mm3 and is fabricated on FR4 substrate as a circular patch antenna with a coplanar ground .The commercially available laminate FR4 substrate that is used has a dielectric constant of 4.4, height of 1.6mm and a loss tangent of 0.0024.The prospective antenna shows a simulated impedance bandwidth of 4.54 GHz. The coplanar waveguide feeding used with this antenna helps in improving antenna performance in terms of its impedance bandwidth as this geometry helps in creating multiple current loops at the antenna structure, thereby exciting nearby frequencies that merge to show a broadband of operation. The antenna’s operational bandwidth is also improved by the concept of modified ground, in which triangular and rectangular shapes are added symmetrically on both sides of ground plane that provide a better fringing effect and hence an improved bandwidth.

Uwb Communication

In this section, we will discuss the design and implementation of a new coplanar waveguide (CPW) antenna, which is designed for use in ultra-wideband (UWB) communication. Two carved ground planes distinguish the radiator from the rest of the chassis. It is necessary to dig a hole in the ruined ground. Circular radiators with rectangular cutouts are excellent for superheterodyne receivers because they have wider bandwidths than other types of radiators. This antenna operates at a frequency of 7 GHz and has a return loss of less than -10 dB. Its working frequency is 7 GHz. When utilising HFSS12, it is possible to determine S11 and VSWR.

Epoxy Material

A spiral fork shaped hexagonal micro strip patch antenna is designed to operate at different frequencies, which are in ultra-wide band range (3.1-10.6GHz). The newly presented antenna is simulated on a Flame Retardant - 4 (FR4) epoxy material with dielectric constant 4.4and overall size of structure is 28*28mm2 . Coplanar waveguide feeding (CPW) is used in this design for easy simulation. This proposed triband structure resonates at 1.36GHz, 5.74GHz and 8.8GHz. The proposed pentaband antenna resonates at 2.38GHz, 3.64GHz, 6.76GHz, 7.36GHz and 8.98GHz with corresponding impedance bandwidths are 200MHz, 70MHz, 170MHz, 520MHz and 420MHz. The peak gains at their resonant frequencies are 1.77dB, 2.45dB, 3.53dB, 4.54dB and 2.28dB respectively with good radiation characteristics. These antennas are suitable for S - , C - and X - band applications.
