چکیده
This paper proposes the design and analysis of co-axial continuous transverse stub multiband antenna (CCTS) for multiple high frequency Applications. Coaxial continuous transverse stub antenna is used to operate on multiple frequency bands with small size and low cost. This proposed antenna consists of two stubs, arranged longitudinally to form a waveguide skeleton like structure. The advantages of CCTS antenna are used to produce omnidirectional radiation pattern in the horizontal plane. This antenna can radiate for the frequency range of 24.5 GHz to 35 GHz which is suitable for portion of K band and Ka band wireless applications. This proposed structure produces very good radiation pattern in both vertical and horizontal plane with minimum acceptable return loss. The simulation software used in this design is CST Microwave Studio and MATLAB. Key-Words:Multiband, Stub, Continuous Transverse Stub, Antenna Array, S-parameter, Radiation Pattern, VSWR.

Multiband Slot Loaded Uniplanar CPW-fed Monopole Antenna with Asymmetrical Arms
This paper presents a new approach for the design of a multiband uniplanar CPW-fed monopole antenna. The antenna consists of a fork like monopole strip to which is added an inverted U-shaped strip. The three branch fork like strip can create three resonant bands within the WLAN range while the placement of the inverted U-shaped strip provides a better impedance matching for the lowest resonant ...

Modern microwave and millimeter wave phased array antennas are attractive because of their ability to steer wave beams in space without physically moving the antenna element. A typical phased array antenna may have several thousand elements fed by a phase shifter for every antenna, which can steer the resulting array beam to different directions. Their low loss, low cost and lightweight phase s...
