Abstract
In a guided missile, a microstrip antenna, including a patch radiator with parasitic elements, flush-mounted and conforming to the side of the missile, producing an antenna beam which is tilted in required direction for use as a link or fuse antenna is shown Parasitic elements are used to direct the beam away from the antenna normal to the desired direction

Planar microstrip Yagi antenna array

John Huang
TL;DR: In this paper, a directional microstrip antenna is designed to provide end-fire beam directivity without requiring power dividers or phase shifters, but the phase shift between signals applied to feed points for circularly polarized signals must be greater than the conventionally required 90° and depends upon the antenna configuration.

Wireless antenna for emitting conical radiation

TL;DR: In this article, the authors describe an antenna with a driven patch that is configured to emit radiation in a broadside direction in response to receiving excitation current, where the driven patch has a first radiating edge and a second edge that are approximately parallel to one another.
Patent

Microstrip patch antenna

TL;DR: In this paper, an integrated directional patch antenna using multiple patch radiating elements to control the direction of a beam of radio frequency energy (RF) over a large scan volume was proposed.

Planar microstrip Yagi array antenna

TL;DR: In this article, the authors introduced the Yagi concept for the planar microstrip array and demonstrated that the beam peak can be tilted toward the end-fire direction by mutual coupling.

Electrically end coupled parasitic microstrip antennas

TL;DR: In this article, the phase relationship and amplitude distribution between the excited fed element and the parasitic element(s) were determined by the phase distribution of the electric field generated in the fed element.
Patent

Dipole antenna with parasitic elements

TL;DR: In this article, a dipole antenna system consisting of a driven dipole element and two parallel parasitic dipole elements equally spaced from the driven element is described, and dual polarization can also be achieved by using two such systems arranged orthogonally.
