Microstrip terminated with load impedance

Using rf toolbox I'd like to model a single port network consisting of a microstrip terminated with an impedance. I have tried lots of things with totally unintelligible error messages. The last, and least plausible attempt was:
MicroStrip_1 = rfckt.microstrip('EpsilonR',2.5,'Height',0.0015,'LineLength',0.1,'Width',0.0045); Network = circuit(); add(Network,[1 2],MicroStrip_1); add(Network,[2 2],resistor(50));

The function circuit() is not to create a network, but to create a circuit that can only contain resistor, capacitor and inductor or other circuits. To create a RF network, look into the constructors that are used to create a network in the below documentation
https://www.mathworks.com/help/rf/ug/rf-circuit-objects.html#bqsq4v_-3
For example, rfckt.series can be used to create a RF network in which the components(or networks) are connected in series.

Thanks Sharan. Despite quite a lot of experience with Matlab, I am finding the RF Toolbox very obscure and difficult to use. If I do as you suggest I end up with a two port network, where I really wanted a single port network. I can combine the 2-port S-parameters to get the S-parameter for a one port network, but I feel like I shouldn't have to do this.
