Abstract A compact ultra-wideband (UWB) square and circular slot ground plane planar antenna with a modified circular patch for UWB communication is presented. This antenna has a low reflection coefficient and high gain in the range of 8.94 GHz, starting from 2.85 to 11.79 GHz. The proposed antenna demonstrates UWB behavior with electrically small dimensions of 0.18 λ0×0.14 λ0×0.015 λ0 (λ0 is the free-space wavelength at 2.85 GHz). The fractional bandwidth of the antenna is 122.1%, with stable radiations. The antenna's maximum gain stands at 2.79 dBi, and the antenna's peak efficiency stands at 72%, respectively. It is lightweight, compact, and easy to manufacture. Hence, it can be used for the complete range of UWB applications and covers Wi-Max/WLAN/ X-Band and Ku-Band.

Fractal is a fragmented geometry which can be segmented into various parts, each part will be the miniature copy of the whole. The main advantages of fractal antennas are its reduced size and multiband operation. These structures have self-similarity properties and fractional dimensions. The self-similar geometrical nature of fractal facilitates the antenna design to achieve multiband applications. The proposed fractal antenna can be operated in different frequencies and 2 frequency bands. The obtained frequency bands are X- band and Ku- band. The proposed antenna has been designed, simulated and analyzed by using HFSS (High Frequency Structural Simulator) software 15.0.

AbstractA novel triple-band microstrip fed planar monopole antenna is proposed and investigated. A fractal antenna is created by iterating a narrow pulse (NP) generator model at upper side of modified ground plane, which has a rhombic patch, for enhancing the bandwidth and gain. Three iterations are carried out to study the effects of fractal geometry on the antenna performance. The proposed antenna can operate over three frequency ranges viz, 3.34–4.8 GHz, 5.5–10.6 GHz and 13–14.96 GHz suitable for WLAN 5.2/5.8 GHz, WiMAX 3.5/5.5 GHz and X band applications respectively. Simulated and measured results are in good agreements with each others. Results show that antenna provides wide/ultra wide bandwidths, monopole like radiation patterns and very high antenna gains over the operating frequency bands.

The sudden development in in wireless applications has leveled up the use of antennas. Multiband antennas are used to operate at different frequencies for the reliability in various applications. This paper presents design of a novel fractal antenna for multiband applications. Attributes of proposed antenna are simulated using Ansoft HFSS. Due to the homogeneous property in the design of proposed fractal receiving wire it has the various multiband applications. Proposed Antenna design consists of FR4_epoxy material with dielectric constant of 4.4, height 1.6 mm. The operating frequency is taken as 2.4GHz. The antenna is simulated. The proposed antenna resonates at different frequencies. The results are measured and return losses are compared. Here the geometry of fractal antenna is analyzed for the C band resonating at 6.2 GHz, X band resonating at 11.9 GHz and Ku band resonating at 13.8 GHz for S11<-10db.
