Collinear Microstrip Patch Antenna - Design of a 869 Mhz Collinear antenna

BiQuad Antenna for 144/440 - This is a vertically polarized Broadside and Collinear Array each Loop is a vertically polarized Broadside Array both the right and the left side of the Loop is a bent 1/2 wave dipole working 180 degrees out of phase with the other one and that gives you 4.15dbi of gain by KE4UYP

BiQuad 144/430 MHz - A vertically polarized broadside and collinear array by KE4UYP

Patch antenna for APT - The patch, or microstrip, antenna has become a common workhorse for the microwave spectrum from about 1 GHz to tens of GHz. This type of antenna consists of two conducting layers separated by a dielectric to form an extended capacitor by WlHDX

Biquad Antenna Construction - This page details the construction of a biquad antenna. The biquad antenna is easy to build, and provides a reliable 11dBi gain, with a fairly wide beamwidth.

SardineCanAntenna - Seattle Wireless  ^updated - Sardine Can Antenna. is a BiQuad or Bi circle - wire length each side (8 x 1/4 waves ) 31 mm

DirectionalBiQuad - Seattle Wireless - A biquad is a fairly powerful antenna which is relatively easy to construct, with impressive performance for their size. A link greater than 5 miles can be made with a pair of these as a stand-alone antenna and a Prism2 100mW card, provided you keep coax short, and your line-of-sight is clear.
