β¦ Synopsis
This paper presents a double slot-lineαmicrostrip transition employing a 90Π cross oΒ¨er them. Using radial stubs at the crossoΒ¨er between the transmission lines, an insertion loss of less than 1.3 dB was ( ) measured 0.65 dB per transition oΒ¨er the 3α15 GHz range. The transition is simulated using a commercial electromagnetic finite-element simulator.

## Abstract A novel wideband design of a microstrip lineβtoβintegrated waveguide (IWG) transition is proposed and demonstrated at the Vβband. The transition is implemented by using a quarter wavelength grounded coplanar waveguide (GCPW) transformer and two shortβcircuited slots. The measurements of

We have verified experimentally that as far as the impedance bandwidth of a /2 patch antenna is concerned, it is better to use a magneto-dielectric substrate as introduced here rather than a dielectric substrate. The measurements indicate that the antenna e
A wideband pentagon-slot microstrip antenna with a semicircle probe feed is proposed. The broadband characteristic is achieved by cutting a pentagon slot at each corners of the patch. The proposed antenna is able to achieve an impedance bandwidth of 68.3% for a VSWR of less than 2. Experimental comp
