High Gain Planar Antenna Structures for Ka-band Applications

A shoulder-mounted planar antenna for mobile radio applications

A new planar antenna, suitable for use on a shoulder, has been studied for police and fire service portable radios in the 350-MHz band. This shoulder-mounted antenna, which is a type of planar inverted F antenna (PIFA), features extreme compactness while maintaining a higher gain than that of a conventional whip antenna and small impedance changes in the presence of a human body. The low-profil...

Implementation of Spiraled Planar Inverted–F Antenna for Multiband Applications

A spiraled planar inverted-F Antenna (PIFA) for Multiband frequencies of 2. 65 GHz, 4. 10GHz and 5. 85GHz for wireless local area network (WLAN) applications proposed in this paper. Simulation tool based on the method of moments (IE3D) has been used to analyse and optimize the antenna. The proposed antenna possesses the properties of good performance, compact size (about 50% of a typical PIFA),...

Planar Directional Beam Antenna Design for Beam Switching System Applications

In this paper, a planar directional beam-switchable antenna with four orthogonal beam directions is proposed. The proposed antenna is designed with two crossed active elements and two parasitic elements for each direction. The design methodology is described on the basis of the Yagi-Uda method for the active and parasitic elements, respectively. By adjusting the effective electric lengths of th...

Multiband and Wideband Planar Antenna for WLAN and WiMAX Applications

Abstract—In this paper, the design of a multiband antenna for WLAN and WiMAX applications is proposed. The proposed antenna comprises a circular radiating patch with a pair of rectangular slits and an inverted U-shaped slot. A hexagon-shaped slot is cut on the ground plane. By adjusting the inverted U-shaped slot, a pair of rectangular slits, and a hexagon-shaped slot, three distinct resonance ...
