A helical antenna is an antenna consisting of one or more conducting wires wound in the form of a helix. In most cases, directional helical antennas are mounted over a ground plane, while omnidirectional designs may not be. The feed line is connected between the bottom of the helix and the ground ... For monofilar designs the radiation is linearly polarized parallel to the helix ... Radiation Properties of a Linearly Polarized Radial Line ... - J-Stage This paper presents the design and radiation properties of a linearly polarized radial line microstrip antenna array (RL-MSAA) with U-slot circular microstrip ... On the Near-Field Shaping and Focusing Capability of a Radial Line ...
A T-antenna, T-aerial, flat-top antenna, or top-hat antenna is a capacitively loaded monopole wire radio antenna [1] used in the VLF, LF, MF and shortwave bands. [2] [3] [4] T-antennas are widely used as transmitting antennas for amateur …

A new type of linearly polarized Radial Line Slot Array (RLSA) antenna developed by FR-4 substrate is proposed for outdoor WLAN point to point application. The WLAN is based on the IEEE 802.1 la standard and the operating frequency range is the upper UNII band (5.725-5.875) GHz. The frequency range is use for point to point microwave link.
