A Wideband and High Gain Microstrip Four-slot Antenna Array

A numerical simulation and an experimental implementation of a cross-shaped, microstripline-fed, printed, four-element slot antenna array are presented in this article. The proposed antenna, with a relative permittivity of 4.3 and a thickness of 1.0 mm...
Since microwave communications equipment is low profile and light weight, low profile and light weight antennas are essential. A microstrip antenna has been developed to meet this requirement. Microstrip antennas offer a conformal structure, low cost and ease of integration with solid-state devices, and are low profile and lightweight....

A Low Cost Pencil-beam Microstrip Antenna at 76.5 GHz

This article describes the design of a 76.5 GHz microstrip antenna using a simple waveguide distributor. This type of antenna permits any complicated radiation pattern to be obtained. It can be used as part of the transmit/receive module for a compact ...
The design of a millimeter-wave antenna with a pencil-beam pattern is complicated when using a slotted waveguide and results in unacceptable dissipating losses, as high as 8 to 10 dB for a microstrip (RT duroid or Cu/PTFE substrate) distributor. This is why most submillimeter-wave antenna designers avoid traditional VHF...
