✦ Synopsis

A new design of a patch antenna with a three-dimensional in¨erted V-shaped patch is proposed and experimentally studied. The three-dimensional in¨erted V-shaped patch is formed by bending a con-¨entional planar rectangular patch at its centerline into an in¨erted V-shape, and it is then supported by nonconducting posts abo¨e a ground plane. The proposed antenna can be excited by using a microstrip feed line through a coupling slot cut in the ground plane of the microstrip line. From the experimental studies, it is found that the proposed antenna can ha¨e an enhanced 3 dB beamwidth compared to con¨entional planar patch antennas when the excitation direction of the in¨erted V-shaped patch is perpendicular to the patch's bent centerline.

Techniques of reducing the oscillator noise of an acti¨e patch antenna are discussed. These include using different depthmetallized ca¨ities, higher dielectric constant substrate, and a low-noise acti¨e de¨ice. Experimental results show that the most effecti¨e method among these is using a deep ca¨i
