This paper presents the design of an ultra-wide band (UWB) circular patch antenna with microstrip line feed and optimization of various antenna parameters. The antenna with dimension of (33 x 30 x 1.5) mm 3 is fabricated on FR-4 epoxy substrate having permittivity constant r =4.3, loss tangent tanδ=0.002. The designed antenna has the capability of operating in the bands (2.7-4) GHz, (6.8-12.5) GHz and (14.6-18) GHz. The antenna performance was modified by inserting a slot in the ground plane to achieve impedance bandwidth (S 11-10dB) in (2.7-20) GHz. The modified antenna was fabricated and tested using the vector network analyzer. The simulated and measured results are presented and compared. The feed line used has characteristic impedance of 50Ω.
Designing the UWB antenna can be one of the most challenging of these issues. UWB antennas must cover an extremely wide band, 3.1 GHz to 10.6 GHz for the indoor and handheld UWB applications, have electrically small size, and hold a reasonable impedance match over the band for high efficiency. One of the printed antennas which has large attention recently is Printed monopole antenna. They offer large band width and are more attractive for wireless communication applications. The large ground plane used for the conventional Printed monopole is the main limitation. However, the move towards the truncated ground plane has made the antenna low profile and suitable for integration into circuit board as terminal antennas. This paper focuses on Printed Circular Monopole antenna design and analysis. Studies have been undertaken covering the microstrip antenna theory. All the types of antenna were simulated and analyzed by using IE3D software. The performance of those antenna are further compared on the basis of parameters like return loss, VSWR, gain etc. From experimental demonstration it is clear that, one can improve the bandwidth of Printed Monopole antenna by inserting the transitions in micro-strip feed line and design can be used as UWB antenna.

There are several challenges in designing of UWB Patch antenna. The first and primary requirement is that the proposed antenna should operate in specified UWB frequency band i.e. 3.1 GHz to 10.6 GHz completely. In addition to this it should have good radiation properties with time domain performance for entire proposed frequency band. The shape and geometry of the radiating patch and ground plane is the major concern for planar UWB antenna designs. Various methods like slotted patch, slotted ground, partial ground, modified feed, truncated corner patch, etc. have been used for increasing the bandwidth of patch antenna There are already several wireless standards which operate in the band of 3.1 to 10.6 GHz. These wireless standards includes WiMax (3.3-3.85 GHz), WLAN (5.15-5.85 GHz) and a portion of X band (8-12 GHz). SIW technology is utilized in microstrip patch antennas to increase gain and to improve the directivity of the structure.
The proposed antenna achieves an impedance bandwidth of 8.9GHz (2.3-11.2GHz) with VSWR< 2 for over the entire bandwidth. Good return loss and radiation pattern characteristics are obtained in the frequency band of interest. The proposed antenna is designed on low cost FR-4 substrate fed by a 50-Ω microstrip line. The simulation was performed in High Frequency Structure Simulator Software (HFSS).

In this paper, coplanar monopole Compact Ultra Wideband (UWB) patch antenna is proposed. It consisted of rectangular shaped patch of Lx = 16mm by Ly = 12:5mm dimensions with two squares profiles into its two corners. Simulated and measured prototype is printed on a partial grounded FR4 epoxy substrate of 30mm by 30mm dimensions. Both of inserted square geometrical shapes provide different electric lengths with variations which are adjusted to enhance the impedance bandwidth and reduce the VSWR between the main resonance frequencies of the rectangular patch. The excitation is launched through a 50Ω microstrip feed line. Design and performances are analysed using Ansoft HFSS electromagnetic simulator based on the finite element method and measured using a vector network analyser where the calibration plane is the SMA connector jack used to connect the antenna. Various prototypes are simulated and measured in order to view the correlation parameter between the impedance bandwidth and the both square geometries.
