International Journal of Microwave and Wireless Technologies, 2014
This paper presents the work carried out to assess the feasibility of miniature directive antennas. It is based on an analysis of the physical limits of antenna directivity in general and in particular as a function of their compact dimensions. A state of the art is done to identify and classify techniques to increase the directivity of compact ...

7th European Microwave Conference, 1977, 1977
Planar, directive, X band antennas were constructed with wide microstrips printed on phainolic paper substrates. Every microstrip functions as a cavity with loses due to radiation from the slots formed between their wide edjes and the earth plane. A number of approximations, mentioned below, form the theory of their opperation. A way is given to cancel

Detection Probability Estimation of Directional Antennas and Omni-Directional Antennas
Wireless Personal Communications, 2009This paper studies the problem of detection of directional antennas and omni-directional antennas by hostile detection systems. We present a model for calculating the probability of detecting a transmitter at arbitrary location around the transmitter. Our study shows that, if a directional antenna employs the same transmit power as an omni-directional ...
