Book excerpt: Technical Report from the year 2013 in the subject Engineering - Communication Technology, grade: A, , course: Electrical Engineering, language: English, abstract: In this report three staircase UWB antennae with WLAN band notch characteristic, each having different ground planes, are presented. These include a Co-Planar Waveguide-fed antenna, a Transmission Line-fed antenna with partial ground plane having a Defected Ground Structure (DGS) and a Transmission Line-fed antenna with slotted ground plane. All the band-notched antennae have rejection characteristics at 5 GHz WLAN band (5.15GHz to 5.35GHz and 5.725GHz to 5.825 GHz) while the antenna with slotted ground plane rejects the 4.9GHZ WLAN band (4.94GHz to 4.99GHz) as well. In all the three antennae the WLAN band is notched by embedding a U-shaped slot in the transmission line. The proposed antennae are carefully designed, simulated and tested in order to fulfill the UWB antennae’s pre-defined criteria. The Simulated and Measured results are found to be in good agreement which show the validity of the suggested designs. Since the commencement of human civilization, humankind attempts to communicate with each other. It is the process of communication, namely the sharing of information, emotions and feelings that has made the mankind the sterling creation of God. It all started with gestures of hands and sounds produced by the vocal cords and gradually evolved into wired and wireless communication now. The orthodox wireless systems were long-range narrowband systems, but in order to use the available spectrum, now, UWB (Ultra-Wideband) short-range systems are being used which consume low power and built using low-priced digital components. The Microstrip Antennae are designed to implement UWB systems, because they show effective results for broadband antennae. Ultra-wideband (UWB) antennae are by far the most essential elements for UWB systems. With the launch of the 3.1GHz to 10.6GHz band, applications for short-range and high-bandwidth portable gadgets are major research areas in UWB systems. Consequently, the acknowledgment of UWB antennas in printed-circuit systems within comparatively small substrate areas is of major significance.

Available in PDF, EPUB and Kindle. Book excerpt: In this dissertation, research and development of a generic band-notching technique that can be applied to any given type of a spiral antenna is presented. A geometrical sub-section of a spiral, strategically placed parallel to the radiating spiral arms, induces spectrally localized impedance mismatch. Initial observation of the phenomenon and the first application of the technique to an equiangular spiral antenna are presented. Detailed parametric study on the structural design parameters that govern the geometry of the stopband structure and the main spiral arms, as wells as substrate properties, is conducted. Through empirical analysis, fundamental concept that explains how band-notching characteristics are induced is theorized within the bounds of a specified problem space. The developed design method is demonstrated and verified with an Archimedean type spiral antenna. Research work on planar spiral antennas with an integrated balun transformer is also presented. Since spiral antennas are fed from the center, it inherently presents a challenge to apply a balun transformer on the same plane as the antenna. By having a three-arm spiral with one of the arms functioning as a balun transformer, coplanar feed to the spiral is established while having a minimal effect on the placement of secondary resonant structures for a stopband response. An UWB equiangular spiral with an integrated balun transformer and the notch filter structure is successfully designed, fabricated and tested. Ultra-wideband spectrum is shared by a number of other wireless standards, which can potentially pose as interference sources in close proximity. A method to target multiple narrowband interferences is discussed. Integration of a multiple number of notch filter structures induces corresponding number of stopband responses. Boundary conditions on design parameters are derived to safely limit the solution space for designers. Successful implementation of the technique is demonstrated through a fabricated UWB antenna with two stopband responses over the 3.4 GHz and 7.4 GHz frequency bands. Higher-order mode filter response using the developed stopband technique is further studied. Integration of a multiple number of notch filter structures at strategic lengths induces corresponding order filter response. Characterization result for higher-order mode filter response and design parameter boundary conditions are presented. Effect on time domain performance parameters is detailed. Successful implementation of the technique is demonstrated through fabricated UWB antennas with the 1st, 3rd, and 5th order stopband responses over the 5.5 GHz frequency bands.
