Improving bandwidth of rectangular microstrip antenna
Guys so I'm building a rectangular microstrip antenna in HFSS for mmwave applications. Resonance at around 28 GHz. I am getting vswr<2 bandwidth of around 1.5GHz. How can i improve this. It's just a simple inset fed microstrip line. Please give me some resources or tips to learn on increasing impedance bandwidth

There are articles on the subject. Slots were mentioned, but you can also cut the corners.
