Milk Jug Patch Antenna

This is not really a “project” in and of itself. Rather it’s a small experiment that me and my buddy Chris ran to investigate two things: Just how well do the figures coming out of the Patch Antenna Calculator that I botched together translate into the real world. How does bending the patch antenna (such as conforming it around a rocket tube) affect its parameters. The antenna itself This antenna was born on a chilly Friday night, in a generic teaching room in Lucy Cavendish College here in Cambridge....

Patch Antenna Calculator

This is a tool I developed to assist us at the Cambridge University Spaceflight Club to design a patch antenna for telemetry. It is intended only as a very crude estimate, as I have absolutely no idea how accurately I selected the underlying formulae. Input Parameters: Dielectric Constant: Dielectric Thickness: mm Target Frequency: Hz kHz MHz GHz Target Impedance: Ω Conductor Thickness: μm Velocity Factor: % Results: Patch Width: Patch Length: Feed Methods: Inset Fed: Inset Length: width length qwt_ Probe Fed: Probe Distance from Center: width length dpf Edge Fed: Edge Impedance: Impedance Required for Quarter Wave Transform: Required Trace Width for Quarter Wave Transform: Required Trace Length for Quarter Wave Transform: 50Ω Impedance Microstrip Transmission Line Width: References Patch Antennas for the impedance formulae Quarter Wave Transformer Microstrip Width Calculator for microstrip formulae DESIGN AND IMPLEMENTATION OF A CONFORMAL OMNIDIRECTIONAL MICROSTRIP ANTENNA ARRAY ON CYLINDRICAL SURFACE Study of a conformal UWB antenna designed on various non-planar surfaces Design and Studies on Non-planar Conformal Patch Antennas for Air-borne Vehicles
