This paper discusses the design of X-band conical horn antenna with coaxial feeding. The idea of pin feeding position and pin length is explored. The important relation between pin diameter and coaxial connector diameter is reviewed in this paper. An improved technique for bandwidth enhancement is also discussed and results are compared with respect to simple coaxial feeding technique. In simulated results, about 76.6% increase in bandwidth is obtained. Computer simulation technology (CST) software was used to simulate the designed antenna. In this paper, design of coaxial to circular waveguide adapter is described, then flare is attached to circular waveguide which acts as conical horn to achieve minimum beam angle and maximum directivity. Practical set up was build for analyzing radiation pattern in E-plane and H-plane. Using this practical set up we have measured half power beam width and calculate directivity. We have compared simulated efficiency with practical efficiency.

Every Telecom Operator is concerned about availability of Microwave link as they are including availability guarantee of 99.999% in SLA. While achieving availability of 99.999%, installation cost is another major factor in consideration due to severe market competition. Three critical microwave links for availability improvement in plain terrain, hilly terrain and water bodies were considered for observation. First traditional techniques of availability improvement such as space diversity, frequency diversity were tried out but these techniques neither gave expected results nor saved cost. Finally new feature of IP radio i.e. adaptive modulation was used to achieve desired availability of 99.999% without increasing installation cost. Adaptive modulation is responsible for improvement in effective fade margin caused availability improvement of microwave link.

The condition for helical antenna axial mode operation according to the classical design data is the wavelength to helix circumference ratio (Cλ) must be in a range of 0.8 to 1.2. In this paper the C/λ ratio reducer to 0.2 for the wavelength 125mm. It is achieved by loading the helix in a back cavity. The design concept of helical resonator filter is used for design of antenna. If the same helix used with 0.75 λ ground plane it operates in normal mode.

This paper describes the design of the triple band rectangular microstrip antenna using inset feed where three bands are combined with only two dual band patches. The antenna is designed to operate in the ISM band at 2.4 GHz, lower UNII band at 5.2 GHz and WiMAX at 3.6 GHz. The dimensions of each single element of the microstrip antenna, at these operating frequencies are calculated using transmission line model. Each element of inset fed antenna will resonate at two frequencies (Hence Dual band patches). The simulation process is done using IE3D and the results are presented in this paper.
